Meeting Code Signing Compliance and Enhancing Security with Code Signing Solution

Securing software is extremely important in the interconnected world in which our industries operate. Every organization today needs to protect each and every piece of software inside their organization from rising digital threats and increasing incidents of software tampering.

This is where code signing comes into play. Code signing is the process of attaching a digital signature to software that confirms the source of the code and guarantees that this code hasn’t been tampered with after signing, which helps build trust. This security measure has become mandatory to maintain the integrity of software and build trust with users or customers.

Now, let’s go over exactly what happens in the code signing process. A cryptographic hash is generated to attach the identity of the publisher to the software. This hash is encrypted with the publisher’s private key, and the users verify the authenticity of the software using the corresponding public key.

If this software had been tampered with after signing, the digital signature attached to it would break, which would alert users to potential issues. This process uses several key steps, adding more and more security by enhancing the integrity of the complete software distribution process.

How does Code Signing work

It’s important to understand each step to ensure the complete process works efficiently and effectively to meet all compliance requirements. These are the following core steps of code-signing: 

  • Generating a cryptographic hash

    A function that is used to generate a unique hash value of the software code. This hash acts as a digital fingerprint that is unique to your software.

  • Encrypting the hash

    This hash is then encrypted using the publisher’s private key to create a digital signature. The signature, along with the public key, is included in the software package.

  • Distributing the software

    The signed software, along with the digital signature, is distributed to the users or customers. The public key is also provided so the users can verify this signature to check the software’s authenticity.

  • Verifying the signature

    When a user receives this software, their system uses the public key to decrypt the digital signature to obtain the original hash. Their system then generates a new hash of the software and compares it with the original hash.

Our code signing product, called CodeSign Secure, helps organizations like yours with the authenticity and integrity of software by effectively following the above process of secure code-signing. We support a client-side hashing technique, which benefits you by giving you faster and more secure data transfer to the server and then creating a unique digital fingerprint.

Later, a digital signature is generated using a FIPS 140-2 level 3 HSM on the server side, and this signature, along with the public key, is attached to the software package on the client side. Now, this signing operation can be done using signing tools like MS signtool Oracle’s JarSigner and by integrating with CI/CD pipelines like Jenkins, Azure DevOps, GitLab Cli, etc. Users can verify the software’s authenticity using the public key attached to the signature.

Compliance Regulatory Requirements 

With digital threats becoming more and more sophisticated and supply chain attacks becoming increasingly common in the industry, stricter compliance requirements are being introduced by regulatory bodies worldwide to protect software integrity. These regulations and standards have made the use of code signing a mandatory security measure for maintaining software integrity and authenticity. Let’s look at these regulatory frameworks and how code signing contributes to these compliances.

Federal Information Processing Standards (FIPS)

In the United States of America, the National Institute of Standards and Technology (NIST) developed the FIPS compliance, which specifies the security requirements for cryptographic modules.  

  1. FIPS 140-2

    This standard is mainly concerned with the security requirements for cryptographic modules within federal systems. It specifies the need for secure key management, integrity verification, and encryption algorithms.

    • Code Signing Applications: Software developers must use FIPS 140-2 compliant cryptographic modules for code signing to ensure that the digital signatures meet federal security standards. Our platform, CodeSign Secure, actively follows FIPS 140-2 compliance and uses the appropriate cryptographic module of Hardware Security Modules (HSMs) for storing the cryptographic keys inside it.

  2. FIPS 186-4

    This standard specifies the Digital Signature Algorithm (DSA) for generating and verifying digital signatures.

    • DSA in Code Signing: DSA for code signing ensures that the signatures are secure, reliable, and meet the federal requirements for software integrity. Our CodeSign Secure ensures the digital signature that has been attached meets these standards or not to build the trust chain.

General Data Protection Regulation (GDPR)

The General Data Protection Regulation is a very detailed data protection law approved by the European Union to protect the privacy and personal data of European citizens or of companies that want to operate out of Europe. Although GDPR focuses mainly on data protection, it is important to ensure the integrity and security of software that handles personal data. 

  • Data Security

    GDPR has made it mandatory for organizations to implement appropriate organizational and technical measures to secure personal data. This means that organizations need to prevent unauthorized access, accidental loss, or any kind of damage to the data. Our solution, CodeSign Secure, has a robust RBAC system that helps to ensure that only authorized developers can access the code signing portal, and we support AD authentication coupled with MFA to allow only authenticated users to onboard.

  • Software Integrity

    Due to code signing, organizations can ensure that the applications handling personal data haven’t been tampered with. By signing software, organizations can ensure that the code is authentic. The digital signature generated by our CodeSign Secure addresses this issue so that the integrity of the software remains intact.

  • Compliance Demonstration

    Using code signing as part of the data protection strategy can help organizations demonstrate compliance with GDPR’s security principles during audits and inspections.

Health Insurance Portability and Accountability Act (HIPAA) 

The Health Insurance Portability and Accountability Act (HIPAA) sets strict standards for the protection of sensitive patient data in the healthcare industry.

  1. Security Rule

    HIPAA’s Security Rule mandates administrative, physical, and technical security to ensure the Confidentiality, Integrity, and Availability (CIA) of electronic protected health information (ePHI).

    • Code Signing Role: By signing healthcare software, organizations can ensure that applications that handle ePHI are secure and have not been tampered with, which also maintains data integrity. You can use our CodeSign Secure to digitally sign ePHI, as we have strong security measures incorporated into our server. No data can be tampered with, and confidential data always remains secure.

  2. Compliance Assurance

    Code Signing can be part of the technical security requirements by HIPAA. During compliance audits, organizations can demonstrate that their software applications are secure and meet the standards. Our CodeSign Secure has extensive logging and audit trails for detailed records of transactions that occur during the code signing process. This ensures that we take all the necessary steps to meet the HIPAA compliance.

Sarbanes-Oxley Act (SOX)

The Sarbanes-Oxley Act (SOX) was created to protect investors by improving the accuracy and reliability of corporate disclosures, mainly financial reporting.

  1. Section 404

    This section requires the management and auditors to establish and report on the internal controls over financial reporting (ICFR).

    • Software Integrity Controls: Code Signing can be used as a control mechanism to ensure that financial reporting software is secure and has not been altered, which helps in maintaining the integrity of financial data.

  2. Audit Trail

    Using code-signing, organizations can create a detailed audit trail for their software applications that demonstrates that robust controls over the software systems are created as required by SOX.

Payment Card Industry Data Security Standard (PCI DSS)

The Payment Card Industry Data Security (PCI DSS) sets security standards for organizations that handle credit card information to protect against data breaches and fraud. 

  1. Secure Software Development

    PCI DSS requires organizations to follow secure software development practices to prevent vulnerabilities in payment applications.

    • Code Signing Requirement: By signing these payment applications, developers can ensure the authenticity of their software, thereby protecting it against malicious code insertion. Our CodeSign Secure only allows authorized personnel to perform code signing operations to make sure your information is always secure and can’t fall into the hands of inappropriate users.

  2. Compliance Validation

    During the PCI DSS compliance assessments, organizations can show that their payment applications are secure and meet the required standards by showing their code signing practices.

Implementing Code Signing Practices

Implementing code signing practices within an organization is extremely important to ensure the integrity and authenticity of the software. This involves several important steps that must be followed to achieve the highest levels of security. Below are the detailed guides for all the steps: 

  1. Obtaining a Code Signing Certificate

    The first step to be implemented in code signing is to acquire a code signing certificate from a trusted Certificate Authority (CA). This certificate acts as a digital identity for the software publisher and is crucial for establishing trust with end-users.

    • Choosing a CA: We strongly recommend that organizations select a reputable CA that is widely recognized and trusted by operating systems and browsers.

    • Certificate Types: You should decide the type of certificate that is needed. Although standard code signing certificates are suitable for most applications, Extended Validation (EV) certificates offer enhanced security and fewer warnings to the end-users.

    • Issuance and Installation: Once the identity of the organization has been verified by the CA, they will issue the code signing certificate to the organization. This certificate must be installed on the system where the code signing will take place.

  2. Integrating Code Signing into the Development Process

    By integrating your code signing into the Software Development Lifecycle (SDLC), you can make sure that all the software builds have been signed before distribution. This integration helps you to maintain regular and consistent security practices throughout your development process.

    • Defining Policies: You need to establish clear policies and procedures for code signing within the development team. This includes which types of software and files will be signed and who will have the authority to sign the code, like a robust RBAC (Role Based Access Control).

      Our CodeSign Secure has a robust RBAC in which we have separate roles defined with specific permissions to perform code signing operations. This will help your organization to keep track of who signs and what they sign.

    • Development Tools Integration: Integrate code signing into your development tools and environment to automatically sign code during the build process, like Jenkins, Azure DevOps, GitLab, and so on. Our CodeSign Secure supports all the different CI/CD pipelines to automate the code signing process. This not only saves you time but also makes the process less prone to human errors.

    • Version Control Systems: You need to ensure that code signing is properly integrated with your version control system (VCS) like GitHub. This helps maintain a history of signed code versions and allows for tracking changes and updates. Our CodeSign Secure supports a build verification feature integrated with GitHub to ensure the code we support in the server is not malicious, and this step helps us avoid one of the most famous cyber security attacks – Solaris attacks.

  3. Securing the Private Key

    The private key used for code signing must be stored securely to prevent unauthorized access to it. If this private key is compromised, it can lead to attackers tampering and then signing code, which in turn undermines the trust in the software.

    • Hardware Security Modules (HSMs): Organizations should use HSMs to store private keys securely. HSMs are physical devices designed to safeguard private keys and perform cryptographic operations in a secure environment. The private keys are stored in a FIPS 140-2 Level 3 HSM in our CodeSign Secure. We ensure the private key doesn’t leave the HSM at any cost, which makes it less prone to tampering.

    • Access Controls: You should restrict access to the private keys to authorized personnel only. It is a good approach to implement RBAC and multi-factor authentication (MFA) to enhance security.

    • Key Rotation and Revocation: You should periodically rotate private keys to reduce the risk of compromise. Also, a backup plan should be in place for revoking and replacing keys in case of a security breach.

  4. Automating Code Signing Process

    By automating code signing processes, you can streamline operations, reduce the risk of human error and ensure consistency. This process is generally important for organizations with frequent software releases.

    • Continuous Integration/Continuous Development (CI/CD): Integrate code signing into your CI/CD pipelines. Tools like Jenkins, GitLab, Azure DevOps, and so on allow for automated code signing as part of the build and development process.

    • Scheduled Tasks: Set up scheduled tasks to sign code automatically at specific intervals or upon certain events.

  5. Testing Signed Code

    Before releasing this signed code, thorough testing is important to ensure that the signing process does not introduce any issues and the code behaves in the desired outcome.

    • Functional Testing: Verify that the signed code functions correctly and that no errors are introduced during the signing process.

    • Signature Validation: Test the signature verification process on different platforms and environments to ensure compatibility and that the signature is trusted.

    • User Acceptance Training (UAT): Perform UAT to ensure that the end-users are able to successfully install and run the signed software without facing any security warnings or issues.

Best Practices for Code Signing

To maximize the benefits of code signing and ensure the security and integrity of software, organizations should stick to the following best practices: 

  1. Use Strong Cryptographic Algorithms

    • Modern Algorithms: We suggest you utilize only modern cryptographic algorithms such as SHA-256 for hashing and RSA or ECC for encryption. These algorithms provide strong security against the latest threats. Our CodeSign Secure supports only the latest algorithms for key generation and hashing methods.

    • Avoid Outdated Algorithms: You should refrain from using outdated algorithms like SHA-1 or MD5, which are susceptible to collision attacks and other vulnerabilities.

    • Regular updates: Your organization and developers should stay updated with the latest recommendations from cryptographic communities and standard organizations to ensure your algorithms remain secure.

  2. Implement Time Stamping

    • Validity Extension: Time stamping ensures that the digital signature remains valid even after the code signing certificate expires. This is essential for maintaining long-term software authenticity. So, we at Encryption Consulting suggest you use only the trusted time-stamping servers when performing the code signing operations.

    • Trusted Time-Stamping Authorities (TSAs): You should use timestamps from trusted TSAs to ensure the integrity and authenticity of the time stamps themselves. Our code signing process only works with the most trusted and industry-specialized time-stamping authorities during signature packaging time.

    • Regulatory Compliance: Many regulatory frameworks require time stamping to demonstrate when the software was signed, ensuring compliance with legal and industry standards.

  3. Regularly Rotate Keys

    • Key Rotation Policies: Your organization needs to establish and enforce key rotation policies to minimize the risk of key compromise. Regularly rotating keys ensures that even if a key is compromised, its impact is less.

    • Automatic Key Rotation: Automated systems are used to handle key rotation, reducing the risk of human error and ensuring timely updates. Our CodeSign Secure has the features of auto key-renewal and key-rotation policies during key generation. This way, we ensure that automated processes are followed, but this feature is optional, so the user can decide whichever option they want to opt for.

    • Secure Key Storage: We encourage the developers to store keys securely using Hardware Security Modules (HSMs) or other secure key management systems to protect them from unauthorized access.

  4. Monitor and Audit Signed Code

    • Continuous Monitoring: You should implement continuous monitoring systems to track the integrity of signed code. This helps identify unauthorized modifications or tampering.

    • Logging and Alerts: Developers should set up logging mechanisms to record all code signing activities. Configure alerting systems to notify security teams of any anomalies or suspicious activities. Our CodeSign Secure has an extensive logging system, which helps in tracking all the code signing activities.

    • Regular Audits: Your organization should conduct regular audits of signed code to ensure compliance with security policies and identify potential vulnerabilities or unauthorized changes.

Your Guide To Do A PKI Health Check

PKI health check is a thorough review of your current Public Key Infrastructure (PKI) to ensure it is working properly, securely, and efficiently. It helps in discovering areas that need to be improved and vulnerabilities and inefficiencies that may exist thereby making sure your PKI aligns with the present-day security requirements and best practices.

Key Areas of PKI Health Check

  1. Review of Architecture

    We should review all the architecture and designs to ensure that they are strong and efficient. We should also check for faults or redundancies and ascertain high availability to maintain seamless operations.

  2. Certification Policies & Procedures

    We should thoroughly examine certification policies and procedures to verify if they are strong enough. Furthermore, check certificate issuance, renewal, and revocation processes.

  3. Security Assessments

    We should ensure that the credibility of the PKI is checked by conducting security assessments on different PKI components such as CAs, RAs, and HSMs. This process involves scanning systems for vulnerabilities and applying necessary patches to sustain the security posture.

  4. Certificate Management

    To ensure PKI security and dependability, effective certificate management must be achieved. Therefore, there is a need for a complete inventory of certificates with periodic checks to ensure their status and completeness. This prevents unauthorized access while protecting the identity of the PKI.

  5. Operational Procedures

    Assessing the effectiveness of operational procedures and incident response plans is important for clarity and effectiveness. The importance of regular testing, backup, and disaster recovery plans cannot be overstated; this ensures that operations can be restored swiftly if there is an outage or other major failure. Additionally, keeping staff abreast with necessary PKI management knowledge, as well as training them in related skills, will always guarantee smooth operation flows.

  6. Compliance and Auditing

    Complying with legal requirements like HIPAA and GDPR is significant for the PKI’s legal and regulatory status. Regular examination of the internal controls that guarantee compliance with these standards is essential. The audits help identify opportunities for more improvements so that PKI operations remain compliant and secure.

Ways to do PKI Health Check

  1. Preparation

    Preparation starts by defining the scope and aim of the PKI health check so that a focused and effective evaluation is ensured. This entails collecting all necessary papers and details about the current PKI installation. It is also important to identify the main stakeholders or staff who are involved in running the organization’s PKI for an inclusive assessment.

  2. Assessment

    In this stage, inputs from stakeholders through interviews are collected to appreciate their perspectives and concerns. For instance, individual components and processes within the PKI can be examined in detail to identify any issues or inefficiencies. In addition, tools and scripts can be used in automating some parts of the assessment process hence improving accuracy as well as efficiency.

  3. Analysis

    Upon reaching the analysis phase, findings from assessments will be reviewed. Consequently, strength areas such as performance excellence can be identified, while weaknesses like system failures are pinpointed in this step. Risk-based prioritization helps to select items for remediation activities.

  4. Reporting

    It is important to write an inclusive report of all findings to document the outcomes of the assessment. This report should also have recommendations for rectifying each identified problem. When the stakeholders are given this report, they will discuss what to do next and hence every other person will be on board.

  5. Remediation

    To remediate means taking measures aimed at implementing recommended corrections for stated mistakes. Any changes made must be tested first. The concerned documents and procedures should, therefore, be updated accordingly with these alterations and developments.

  6. Continuous Monitoring

    A regular schedule for checking PKI’s health is necessary in order to keep it secure and efficient. In addition, continuous monitoring of PKI infrastructure helps in early detection and mitigation of any new problems that may occur within it.

    Proper risk management must be achieved by identifying and dealing with potential risks. This will entail ensuring proper incident response and disaster recovery planning measures and proper implementation of effective risk management strategies. Good risk management safeguards the PKI infrastructure from attacks and ensures business continuity is always met.

Best practices 

It is very important to maintain the health of your Public Key Infrastructure (PKI) to ensure its safety, dependability, and efficiency. Here are some best practices to help you maintain a robust PKI infrastructure. 

  • Regular Audits and Assessments

    Regular audits and assessments help in maintaining a secure and compliant PKI. Plan for periodic internal audits to assess PKI policies and procedures to ensure configurations follow the standards and regulations. This should be combined with external auditors who will perform independent assessments and provide unbiased views on the health of your PKI. There should be regular risk assessments conducted to identify possible threats as well as vulnerabilities.

  • Certificate Lifecycle Management

    Effective management of the certificate lifecycle is vital to minimize disruption and uphold trustworthiness. Use automated tools for certificate issuance, renewal, and revocation that reduce human errors, thus improving efficiency. Keep an accurate inventory of all certificates including their expiry dates. Implement alerts or notifications for upcoming certificate expirations to ensure timely renewals.

  • Key Management

    Security of cryptographic keys requires proper key management practices. Use hardware security modules (HSMs) to store and manage keys securely. Regularly rotate cryptographic keys to minimize the risk of compromise. Have strong backup and recovery procedures for the keys to ensure continuous services when they are lost or damaged.

  • Access Control and Security

    It is crucial to implement strict access control and security measures to protect PKI components and sensitive information. Use role-based access control (RBAC) on PKI components to allow only authorized individuals to access them. Ensure multi-factor authentication (MFA) is enabled for PKI system access and critical operations performed on PKI systems. Physical security of the PKI hardware and data centers should be ensured against unauthorized access and tampering.

  • Monitoring and Logging

    PKI health and security is reliant on continuous monitoring coupled with detailed logging. Implement real-time monitoring tools that track the health and performance of the various PKI components, and looking out for anomalies or potential security breaches occurring during this process is imperative. Enable comprehensive logging of all activities related to your PKIs and keep logs for a reasonable period suitable for audit purposes or forensic analysis purposes. Create alerts for significant events such as certificate expirations, key compromises, system failures, etc.

  • Incident Response

    An incident response plan that focuses on incidents related to PKI must be built and maintained to ensure an immediate and appropriate response when a problem occurs. The plan should be well known by all employees so that they understand their respective roles. After any incident, conducting post-incident reviews allows the organization to identify lessons learned and improve incident response procedures, thereby enhancing the overall resilience of the PKI infrastructure.

  • Compliance and Policy Management

    To maintain a secure PKI environment that is compliant, it is important to keep up with regulatory changes and industry standards. Changes in technology, regulations, or organizational needs necessitate regular review of PKI policies. A complete reference for all PKI management requirements should be prepared in form of documented policies, procedures and configurations that can be easily accessed by authorized personnel.

  • Continuous Improvement

    In order to drive continuous improvement of PKI management, it is critical to create feedback loops that can gather insights from audits, incidents, and daily activities. Through informed adjustments made using this feedback, organizations may become proactive in preventing possible issues and improving their PKI processes. Moreover, staying up to date with PKI best practices, integrating them into organizational procedures and engaging with the wider PKI community contribute to an improved and adaptable PKI infrastructure.

  • Disaster Recovery and Business Continuity

    High availability and reduced downtime during failure cases are achieved by implementing redundancy and failover mechanisms for key components of a public key infrastructure. In addition, the development of a disaster recovery plan that is periodically tested is necessary for quick restoration in case of major incidents.

Identity Governance: The Key to Secure and Efficient Access Management  

In the digital environment, being in possession of authentic user credentials is like being granted a VIP pass to an organization’s assets. This is because the use of such credentials does not alert the security systems and mechanisms in place. 

Suppose there is a big organization with thousands of employees, contractors, and business partners who interact with hundreds of applications daily. Every access point is a threat that can be exploited by an unauthorized person. Hackers, in turn, require only one vulnerable spot among these millions of potential threats.

With one single set of valid user credentials, they can easily get into the system through phishing or malware, or through a simple user error. This highlights the critical need for strong identity governance to protect against unauthorized access and secure the organization’s assets. 

Due to the fact that identities are such desirable targets for attackers, their protection is crucial. Identity governance is the foundation of protection that needs to be implemented to enhance the security of the systems.  

Defining Identity Governance

Identity governance can be defined as the set of policies, processes, and tools that are employed in the administration of access to information systems. It helps in making sure that the correct people get the correct kind of access to the technology resources at the right times for the correct reasons. 

Identity Governance vs. General IAM 

Identity governance is a part of Identity and Access Management (IAM). While IAM is the overall framework for managing digital identities and controlling access to resources, identity governance is the governance part which means management, compliance and risk of identities. 

IAM includes the technical infrastructure and processes to create, manage and authenticate digital identities and authorize access to resources. Identity governance is the policies and oversight mechanisms to ensure identities and access rights are managed in a way that complies to regulations and organizational policies and risks are mitigated. 

Why is Identity Governance Important?

Enhances Security  

In today’s world, security breaches are a big deal. Unauthorized access to sensitive info can mean data breaches, financial loss, and reputational damage. Identity governance stops this from happening by ensuring only the right people have access to the right resources.  

  1. Proactive Threat Detection

    By monitoring user behavior and access patterns, identity governance can detect unusual activity that may be a security threat. This proactive approach means you can fix vulnerabilities before they’re exploited. 

  2. Reduces Human Error

    Human error is a common cause of security breaches. Clear policies and automated processes in identity governance reduce the chance of mistakes like over-privileging or not revoking access when it’s no longer needed.

  3. Fine- Grained Access

    Identity governance lets you control access down to the level of individual resources, so users only have access to what they need for their role. 

Ensures Compliance  

Many industries have strict regulations around data and access control. Identity governance helps you comply with those regulations by providing a framework for user access and audit trails.  

  1. Audit Readiness

    Detailed logs and reports of user activity are key to passing audits. Identity governance ensures those logs are complete and easily found. 

  2. Policy Enforcement

    Consistent enforcement of access policies across all systems and applications means regulatory compliance. Identity governance ensures all access controls align with regulation.

  3. Data Regulation

    GDPR, HIPAA, and SOX require access controls over sensitive data. Identity governance helps you implement and manage those controls.

Reduces Risk

By having robust identity governance in place, you reduce the risk of insider threats and external attacks. Identity governance minimizes the chance of unauthorized access and helps you detect and respond to security incidents faster.  

  1. Insider Threat Mitigation

    Identity governance also helps in monitoring the users and their activity within the organization to prevent insider threats. This is especially so because access reviews and audits, which are usually conducted on a regular basis, can reveal such activities that might point to an insider threat. 

  2. Rapid Response

    In the event of a security incident, identity governance allows organizations to easily identify the particular accounts that have been compromised and shut them down before they can cause significant harm or before the response time to the incident is too long. 

  3. Third-Party Risk Management

    Controlling and monitoring third-party access is key because external vendors and partners can introduce vulnerabilities. Identity governance ensures third-party access is monitored and controlled tightly, reducing the risk of unauthorized access through these external connections.

Improves Operational Efficiency

Identity governance simplifies the management of user identities and access. Automated workflows and self-service reduce the workload on IT.  

  1. Automated Provisioning

    Identity governance provisions user accounts and access rights based on role and policy. This means IT staff no longer have to manually set up and adjust access permissions. Automation also eliminates errors as access rights are assigned consistently and correctly, not manually.

  2. Self-Service Portals

    Self-service portals allow users to request access to resources and reset passwords without IT.

  3. Consistency and Accuracy

    Automated processes ensure access rights are assigned consistently and accurately, reduce errors, and increase efficiency.

  4. Resource Utilization

    By reducing manual effort in identity management, organizations can utilize their IT resources better, so staff can focus on strategic initiatives and drive more innovation and productivity.

Enhances Accountability and Transparency  

  1. Clear Accountability

    Identity governance provides clear accountability by tracking who has access to what and why. This visibility helps in identifying responsible person in case of security breach and ensures access is granted for business need. 

  2. Visibility

    Identity governance gives you visibility into access patterns and anomalies which is key to a secure and compliant environment. You can see who has access to what and why so you can identify the person responsible in case of a breach. Additionally, visibility into access patterns helps organizations ensure access is granted for legitimate business needs, enhancing accountability and transparency in access management practices.

Supports Business Growth

  1. Scalability

    As the organization grows, managing identities and access rights can get complex. Identity governance practices are designed to scale with the organization, so access management remains efficient and secure as the user base grows.

  2. Mergers and Acquisitions

    During mergers and acquisitions, integrating systems and managing access can be tough. Identity governance simplifies these processes by providing a single framework to manage identities across multiple systems.

By securing, complying, reducing risk, increasing productivity, and supporting business growth, identity governance is an essential part of modern management. Implementing identity governance practices not only protects sensitive information but also enables organizations to run better.

Main Elements of Identity Governance

Identity governance is a core organizational framework for ensuring that user identities and access are properly managed and controlled. The main elements of an identity governance framework include:  

Identity Lifecycle Management

Identity lifecycle management covers the entire lifecycle of a digital identity for each user from creation to deactivation. Identity lifecycle management includes: 

  1. Provisioning

    Granting access to new users based on their roles and responsibilities within the organization. Provisioning creates new accounts and assigns the relevant access to each. New employees, contractors and partners can get access to the resources they need to get up and running quickly.

  2. Updating

    Users roles and responsibilities within the organization change. Their access rights must change too. Updating ensures users have the correct access rights for their current job functions and assignments. Users should not have too much or too little access.

  3. De-provisioning

    Users who leave the organization or no longer need some of their access rights must have their accounts deactivated or modified as soon as possible. De-provisioning ensures former employees, contractors or partners can’t log in to organization systems and reduces the risk of unauthorized access.

Role-Based Access Control (RBAC)

RBAC is an access control mechanism that limits access to a system based on individual users’ roles within a business organization. Access is determined by specific user roles in which permissions are assigned to users who belong to particular roles.  

  1. Defining Roles

    Defining roles clearly within the business organization is the initial process of applying RBAC. Every role corresponds to particular job functions and duties. Users’ access should not be more than the minimal required to perform their job responsibilities.

  2. Assigning Access

    Access should be assigned after determining the roles. With this approach, access rights become easier to manage and monitor since changing users’ access only requires altering their roles instead of modifying their individual permissions.

  3. Preventing Unwanted Access

    RBAC limits access to information and systems that users need to do their job. This is called the principle of least privilege. The principle of least privilege means users have only what they need to do their job and no more. By following this principle RBAC prevents users from having too many privileges that would allow them to access data and systems they shouldn’t and reduces the risk of data breaches and other security threats.

Policy Management

Sound identity governance requires strong policies in place that define the rules for how identities are to be managed, and what access rights users should have to resources. Policies need to be documented, reviewed, and updated as changes arise within the organization, or as new regulatory requirements need to be addressed.  

  1. Policy Documentation

    Policies should be well documented and available to all relevant stakeholders. This documentation serves as a reference point for how identities and access rights should be managed throughout the organization.

  2. Regular Reviews

    Policies should be reviewed and updated as changes arise within the organization, such as new business processes that need to be supported, new regulatory requirements that must be addressed, or new security threats that pose a danger to the organization. Reviews should occur with regularity to ensure policies are relevant and effective.

Access Reviews and Certification

Performing regular access reviews and certification is vital to uphold efficient identity governance. Access reviews consist of periodically reviewing and ensuring users’ access rights are valid for their assigned roles.  

  1. Periodic Reviews

    It’s essential to conduct access reviews periodically, e.g., every three or twelve months, to ensure the access rights are valid for the allotted roles. When performing access reviews, supervisors and business owners review and attest that users have the right access to the jobs they perform.

  2. Certification

    Certification involves formally verifying and documenting that access rights are appropriate and comply with organizational policies. This process helps identify and remediate any discrepancies or potential security risks.

  3. Remediation

    Any gaps identified during the access review should be remediated as soon as possible. This may include removing excessive access permissions, refreshing role definitions, or changing user roles to reflect the latest business rules.

Audit and Reporting

Identity governance requires the retention of granular logs of users and their access. These access logs are critical for auditing the access and actions of users in the system.  

  1. Granular Logs

    Granular logs of all user activities, including access requests, approvals, and denials. This data captures who accessed what and when. This data is critical in investigating security breaches and in demonstrating compliance.

  2. Periodic Reporting

    Periodic reporting of trends, anomalies, and overall improvements in the organization’s security posture. These reports need to be viewed by appropriate stakeholders to ensure that user activities and access rights align with organizational norms.

  3. Demonstration of Compliance

    Granular audit logs and reports are required to demonstrate compliance with regulatory guidelines. During regulatory audits, this data serves as proof that the organization is practicing proper identity governance and is compliant with relevant regulations.

Organizations that focus on these critical elements can establish a strong identity governance foundation that helps strengthen security, maintain compliance, mitigate risk, and support operational efficiency. Effective identity governance can help protect sensitive and critical organizational assets as well as support the organization’s broader objectives and goals.  

Good Identity Governance Practices

Engage Stakeholders  

Identity governance is not just an IT task. Engage stakeholders from all areas of the business, including HR, legal and compliance, to bring a comprehensive approach to identity governance.  

Create a Security Culture

Create a security culture by offering regular training and awareness sessions to employees. Encourage users to adhere to identity and access management best practices and to report suspicious behavior.  

Employ Automation

Automation offers tremendous opportunities to improve identity governance efficiency and effectiveness. Employ automated tasks for provisioning, updating, and de-provisioning user access. Use automated access review certification to minimize manual effort and increase accuracy.  

Review and Update Policies

Review and update your identity governance policies on a regular basis to account for changes in organizational structure, regulatory requirements and threat vectors. Ensure that policies are still valid and address areas that could increase risk.  

Perform Regular Audits

Performing regular audits ensures compliance and uncovers potential security concerns. Audit user access and behavior periodically to ensure appropriate access rights and that no unauthorized behavior has taken place.

How to Improve Security Using Centralized Multi-Factor Authentication (MFA)?

Data breaches are happening more frequently than ever before, making organizations’ security defenses weaker and requiring continuous updates in their strategic planning and security measures to keep the constantly advancing threats at bay. In just 2023, there were an estimated 2,814 incidents of data breaches, according to IT Governance. A study by the Harvard Business Review shows that these incidents of data breaches increased by 20% from 2022 to 2023.

Several vulnerabilities in the contemporary authentication infrastructure have resulted in a large number of cases of exploits. The several instances pointed out were the Cloud Misconfiguration, like improperly secured S3 buckets exposing sensitive data, evolved ransomware attacks like Ryuk ransomware attacks targeting healthcare institutions, and increased exploitation of vendor systems such as SolarWinds supply chain attacks compromising widely used software.

In most cases, the reasons behind these malicious actions involved an absence of a strong authentication layer, which resulted in vulnerabilities that were easy to exploit. The lack of proper monitoring only makes the situation worse by causing the organizations’ security defenses to become weaker leading to compromised systems staying undetected for far too long. These incidents highlight the critical need for a strong and secure authentication process that can protect organizations from even the most sophisticated attacks.

Why is Traditional Single-Factor Authentication Falling Short?

As we know, the traditional authentication system uses single-factor username and password matching. This was reliable for a very long time, but with the rapid advancement of technologies, there has been an unprecedented need for organizations to do more to protect their data. In recent decades, we have seen significant breakthroughs in computational power and technologies, including artificial intelligence (AI) and high-performance computational units such as GPUs, DPUs, and more.

These advancements have made single-factor systems increasingly vulnerable to various exploit strategies, including GPU-accelerated Brute-force attacks, credential stuffing by AI-powered bots, and social engineering or phishing attacks. This leads to an increased likelihood of attackers succeeding in cracking a password, giving them complete access to all accounts for which the user has reused the credentials. And the recent news highlights the dangers that organizations are facing:

  • In June 2024, cloud vendor Snowflake reported a cyber threat targeting customers who relied on single-factor authentication. While the exact details are still emerging, it is clear that organizations need stronger authentication measures to prevent compromise.  
  • CISA (Cybersecurity and Infrastructure Security Agency) in the US added single-factor authentication to its list of “Bad Practices” in August 2021. It clearly highlights the growing consensus among security experts that single-factor authentication is no longer sufficient for online security. 

Why is Multi-Factor Authentication (MFA) Essential? 

Multi-factor authentication (MFA) serves as a security measure that emphasizes user identity verification through more than one authentication method. These extra methods include a fingerprint or a one-time code sent to the user’s phone to log in to an account or system. The idea fundamentally focuses on identifying the user from multiple authenticated sources before giving them access to the resource they are trying to log into. 

Two factor authentication workflow

In a simple single-factor authentication, there is only a single criterion for authentication, but MFA adds multiple layers of security to the authentication, making it an ideal choice for organizations. However, the important question is how organizations can secure their resources with MFA. To answer this, we can take the example of these situations: 

  • We all know of scenarios in our organizations where sometimes employees leave on less-than-amicable terms. With a single password authentication system, a discontented ex-employee could potentially wreak havoc on the organization’s systems if they still possess the login credentials.

    MFA throws up a roadblock to this issue, requiring an extra verification step (like a machine identity or geo-location matching). Now, even if the credentials are leaked, they still won’t have access to the company’s sensitive data.

  • Another scenario involves, if a corporate system or device is compromised, the company’s sensitive files, services, and resources are exposed to outside threats. A simple authentication method will fail in cases where the password is saved. But, for an MFA-enabled system, logging into the resources would need more than just one authentication, making it a lot more difficult to gain access to the compromised system.

There are several reasons why we consider MFA as the most powerful solution that organizations currently require to prevent attackers from gaining unauthorized access to the systems, even if the credentials are forged. So, what are the considerations to integrate a centralized MFA into an organization’s Access Management? Let’s find out next.

How to Integrate a centralized MFA to Organization Access? 

Well, it can be a challenging task to identify the correct MFA design and criteria. If we have a proper understanding of requirements and planning, integration of MFA with organizational access management becomes easy. We will be discovering the key steps and strategies that you need to follow for the seamless integration of MFA: 

Step 1: Understanding Your Security Posture

Firstly, it is important to know what you are working with and that starts with evaluating your current systems. Here we are looking for potential vulnerabilities in existing login protocols and overall security posture. This assessment will help you to identify areas where stronger authentication measures like MFA can be most beneficial.

Step 2: Choosing the Right MFA Method

There are various MFA methods available, each with its advantages and considerations.

  • Two-Factor Authentication (2FA): The system requires the user to enter their password and one additional form of identification, such as a verification code sent to their phone or email. 
  • Third-Party Authenticator App: Instead of the system itself, a third-party application (authenticator app) verifies the user’s identity by generating a passcode that the user has to enter to confirm the identity of the system. 
  • Biometric Authentication: Biometric Information, such as scanning a fingerprint, retina, or other unique physiological features, serves as the system’s authentication. 
  • Device Recognition: The system prompts for multiple authentications only when accessing it for the first time on a new device. Subsequent access from recognized devices requires only the user’s password, as the system remembers the device’s identity.

We recommend that you consider several parameters while opting for an MFA option, including ease of use, security strength, and compatibility with the existing organization’s infrastructure. Based on the identified security requirements, multiple MFA options can also be a good decision.

Step 3: Identity Management System Integration

After the MFA solution option is selected, it needs to be integrated with the existing identity management system (e.g., Active Directory, Azure AD). It is better to have centralized user management from a single point of control. It enables consistent enforcement of MFA policies across the organization.

Step 4: Testing and Refinement

Additionally, it should also be necessary to conduct thorough testing of the MFA implementation to identify and address any potential issues with the deployment.

Is just a Centralized MFA integration enough?

Unquestionably, a centralized multi-factor authentication system offers robust security for the organization’s priceless assets. It simplifies the user management procedure and has many benefits while implementing uniform security guidelines across the entire company. However, a number of restrictions need extra security precautions into account: 

  • Conditions for Static Authentication

    Typically, pre-established authentication factors like one-time passcodes sent by SMS or authenticator apps are used by Centralized MFA solutions. Although these techniques are a big improvement over using passwords alone, they are not flexible enough to counteract advanced security threats.

    A stronger MFA element, like a hardware token or biometric verification, is necessary for a higher-risk login attempt, such as one made from an unusual place, time, or device, while low-risk logins, such as a regular user coming in from their typical office network, don’t.

  • Limited Access Control Granularity

    We recommend against using a one-size-fits-all MFA policy that applies to all organization units, as this ignores the differences in access requirements between departments or user roles. We can use privileged users who manage extremely sensitive data, such as bank records or intellectual property, as an example.

    When it comes to regular internal programs like email or collaboration tools, they ought to demand more stringent authentication procedures than those associated with basic user logins.

  • Human Element Vulnerability

    Although multi-factor authentication (MFA) methods are supposed to provide robust security, users who are not sufficiently taught in security best practices may fall prey to social engineering and phishing schemes. Users may fall victim to a deceptive email that poses as a reliable source (such as a manager or IT help) and deceive them into disclosing their MFA credentials or clicking on a malicious link that compromises their machine.

These restrictions allow room for development even though they do not directly present a serious security hazard. We will examine ways to close these holes and improve our company’s security posture in the following part. 

How to improve the MFA’s strengths and management? 

We’ve already talked about the drawbacks of MFA-enforced security solutions. We will investigate many cutting-edge approaches that go beyond static criteria and offer a granular and risk-based strategy to address such difficulties. Let’s examine these tactics and the situations in which they are applied: 

  • Adaptive Authentication

    Using contextual data that is updated in real time, an adaptive authentication system dynamically modifies the MFA requirements.

  • Risk-Based Authentication

    This technique assesses the possible danger involved in every attempt to log in.

  • Biometric Authentication

    A strong layer of security is provided by biometric authentication techniques, such as fingerprint, iris scan, or facial recognition, especially for privileged user accounts or access to extremely sensitive data. Each person possesses these distinct biometric characteristics, which greatly lessen the likelihood of password theft or token abuse.

    By using facial recognition software or fingerprint scanners for biometric authentication, the dangers associated with popular attacks like credential stuffing and password spraying are reduced. Numerous businesses, like as Suprema and HID Global, offer biometric solutions to businesses.

    Regulating biometric authentication varies by region, and it’s crucial to recognize that biometric data collection and storage present privacy concerns. It is advisable that you thoroughly evaluate the ethical and legal ramifications prior to implementing biometric authentication systems.

  • Security Awareness Training

    An effective security awareness program can have a long-term positive impact on the firm by teaching staff members about cybersecurity best practices. It is advisable for firms to conduct employee training and awareness campaigns regarding the best practices and functionalities of secure MFA login procedures.

  • Geo-fencing

    A user’s usual geo-location, such as their home or office, is tracked by the system. Attempts to log in from outside this zone use more robust MFA, such as a hardware token or fingerprint scan, than logins from known locations made during regular business hours. For this, you can use tools like Azure Active Directory Geofencing with Azure Maps or Google Maps Platform.

  • Device Recognition

    Attempts to log in from known devices, such as a business laptop or a personal phone, are recognized and trusted by the system. Additional verification steps are necessary for logins from unidentified devices, such as a public computer or a new phone. Device management and identification are aided by mobile device management (MDM) programs such as VMware Workspace ONE and Microsoft Intune.

  • Time-based Factors

    Repeated attempts to log in by a single person in a short amount of time, particularly unsuccessful attempts, point to suspicious activity and need to prompt more robust multi-factor authentication.

  • Historical Behavior

    Repeated attempts to log in by a single person in a short amount of time, particularly unsuccessful attempts, point to suspicious activity and need to prompt more robust multi-factor authentication.

  • Monitoring

    An ongoing method for monitoring the MFA system needs to be implemented. This will help expose usage and examine login attempts for unusual activity. The information obtained by this approach will help generate reports identifying possible security breaches and areas for improvement.

  • Threat Intelligence Feeds

    Real-time information on new threats and attack vectors is available through services like Palo Alto Networks Threat Intelligence and Cisco Talos. In order to dynamically modify authentication requirements based on the most recent threats, this data can be connected with MFA regulations.

  • Anomaly Detection

    Login attempts originating from suspicious locations, known malware sources, or involving unusual access times are flagged as high-risk and trigger additional MFA steps. Security Information and Event Management (SIEM) systems, like Splunk, Palo Alto Cortex, or Elastic SIEM, can analyze security logs from various sources (firewalls, endpoints, MFA systems) to identify unusual patterns.

  • Identify Phishing Attempts

    Phishing emails frequently aim to deceive recipients into disclosing login information or clicking on harmful links. Users can spot warning signs such as generic greetings, dubious sender addresses, or misspelled URLs with the aid of appropriate education and awareness.

  • Maintain Strong Password Hygiene

    Users can drastically lower the risk of password compromise by creating complex passwords (using a combination of capital and lowercase letters, numbers, and symbols) and not reusing them across platforms. Tools for managing passwords, such as 1Password or LastPass, are beneficial.

  • Avoid Social Engineering Tactics

    Social engineering involves manipulating users into giving away sensitive information or taking actions that compromise security. Training can help employees identify these tactics and avoid falling victim to them.

  • Report Suspicious Activity

    Procedures for managing anticipated security breaches involving compromised MFA credentials should be clearly outlined in an incident response plan. It is advisable to motivate staff members to swiftly notify the IT security team of any questionable activities, including phishing scams or odd attempts at login.

  • Compliance Management

    Organizations should be required to guarantee that the MFA solution they have installed complies with all applicable security legislation and compliance standards, such as PCI DSS and HIPAA.

Creating a Multi-Layered Authentication Framework 

Even while legacy MFA provides an essential security layer, not all risks can be addressed by it. Even the more traditional multi-factor authentication (MFA) methods need to be strengthened against more complex cyberattacks. We’re going to learn how to integrate the current centralized MFA system with a multi-layered authentication framework:

  • Integration with Security Information and Event Management (SIEM) systems

    Important insights into possible threats and suspicious activities may be gained via a centralized procedure for the logging and analysis of authentication events from many sources (MFA logs, firewall logs, and endpoint security logs).

    SIEM systems provide the ability to detect abnormalities, correlate login attempts with other network activity, and send out notifications for any security problems.

  • Endpoint Security Integration

    Organizations can improve authentication by integrating multi-factor authentication (MFA) with endpoint security solutions such as Microsoft Defender for Endpoint or CrowdStrike Falcon. This allows for the verification of access attempts based not only on user credentials but also on the security posture of the device. Before providing access, this entails assessing elements, including device health, the availability of security software upgrades, and compliance with corporate security rules.

  • Contextual Authentication Policies

    To customize MFA requirements depending on certain factors like user roles, the sensitivity of the data being accessed, or the location from which access is sought, we suggest enterprises create contextual authentication rules. With less user friction in everyday circumstances, our modular approach guarantees that stronger authentication mechanisms are deployed when they are most needed.

  • Continuous Monitoring and Response

    In order to identify suspicious activity (such as repeated unsuccessful login attempts from a banned IP address) or abnormalities during the authentication process in real-time, continuous monitoring capabilities must be used. Automatic countermeasures can also be initiated to mitigate any security breaches quickly. These could include tightening authentication requirements or preventing access until more verification is received.

  • Advanced Threat Intelligence Integration

    We also recommend taking into account feed services for advanced threat intelligence. Giving real-time information about new risks and attack pathways improves MFA security. Organizations may respond dynamically to sophisticated security risks by adjusting their authentication tactics through the integration of threat intelligence with MFA rules.

  • Regular Security Audits and Penetration Testing

    To find weaknesses in the authentication infrastructure, regular security audits and penetration testing must be carried out. By simulating actual cyberattacks, these vulnerability evaluations find flaws and holes and confirm that MFA rules and processes are effective. Organizations may effectively enhance their authentication procedures against more sophisticated and hazardous potential attacks by conducting regular audits.

Balancing Security and User Experience to avoid the MFA Fatigue 

We have spoken about how crucial MFA is to obtaining organizational resources. Additionally, we now know the approaches and procedures for putting robust authentication into practice. Prioritizing the authorization process’s user experience to make it simpler for employees to utilize is equally critical as maintaining security standards. Users that experience MFA fatigue due to the excessive steps needed to access the resources they need can be caused by an overly complicated authentication workflow.

MFA fatigue has a negative impact on output and the completion time of tasks that require urgency. Choosing weaker passwords or breaking security procedures are two dangerous behaviors that frequently result from this dissatisfaction. We can think about the following suggestions to avoid such problems in the future: 

  • Balancing Security and Usability

    We think it’s critical to strike a balance between robust security and an easy-to-use interface. Context-aware authentication, in which the MFA technique adjusts according to risk factors, can be used to do this. Routine login attempts from known devices or networks, for example, require less complex authentication techniques, but suspicious activity necessitates more thorough verification procedures.

  • Usability Testing

    To detect and reduce any friction points or complications in the authentication process, we also suggest regular usability testing as a way to help you prevent MFA fatigue. User input is a key component of this approach. By improving workflows, organizations can optimize authentication procedures and improve user experience and security at the same time. By using an iterative process, security protections are maintained without sacrificing usability.

  • Education and Awareness

    Users must always be made aware of the dangers of compromising security for convenience, as well as the significance of using strong authentication procedures. It is imperative for organizations to prioritize raising knowledge of the advantages of a centralized multi-factor authentication system, discussing potential risks, and offering unambiguous guidance on navigating authentication procedures.

Conclusion 

Centralized MFA is an important security measure, but we recommend that it should not be your only line of defense. Companies need to take a multi-layered approach and acknowledge its limitations.  Always keep in mind that maintaining security is a continuous process. We can establish a more robust security environment for our organizations by combining the layered authentication approach with security awareness training and continuous threat monitoring.

Detailed Guide To Meeting NIST SP 1800-16 Compliance

NIST SP͏ 1800-16 has recently released their new ͏͏guidelines for managing TLS certificates. The core emphasis has been put on preventing, detecting and recovering from certificate-related incidents that are becoming increasing commonly these days. These guidelines help organizations to navigate a secure roadmap for implementing effective TLS certificate management programs to avoid risks and maintain a secure and strong cybersecurity posture. By following these guidelines, you will enhance your organization’s ability to authenticate and secure online communications and prevent the looming threats from impacting your organization.

We will also provide with the best practices recommended by NIST when it comes to certificate issuance, renewal, and revo͏cation ensuring ongoing security and compliance with the industry best practices and standards. With advanced happening in our industry at an unprecedented pace, these guidelines are important for maintaining the integrity and trustworthiness of your organization’s digital communications.

Understanding th͏e guideli͏n͏es of NI͏ST ͏͏SP 18͏00-16 ͏is crucial. Ho͏wever, to f͏ully grasp thes͏e guidelines, it is essential͏ to have a clear un͏derstanding of what a TLS certificate is͏ and it͏s importance.

Importance of TLS cert͏ificat͏es

Ev͏erything on th͏͏e Internet is just a ͏click awa͏y, be it exch͏anging billions of ͏dollars or highly confidential info͏rma͏͏tion ͏that is worth millions. When a person uses͏ t͏he Internet as a client a͏nd is a͏bout to fill out th͏eir pers͏͏onal, va͏luable͏ information, they know͏ that the sit͏e is safe to use beca͏use of these ͏TLS certificate͏s in place. This is al͏l driven by trust i͏n secure Internet connections. At͏ the heart of this trust is T͏ransport Layer S͏ec͏ur͏͏i͏ty (TLS), a cryptog͏͏ra͏phic͏ protocol th͏at ensures secure communication͏s and pro͏vides͏ ͏a s͏ense ͏of reassurance and con͏fidence to the billions of users across the world. 

A TL͏S certificate pl͏ays many roles and some of them are: 

  • Provi͏ding a laye͏r ͏of authen͏tication between the client and server systems, ͏building trust ͏in the in͏ternet connection, and ensuring the securi͏ty and authentication of online transac͏tions͏.  
  • This is a significant responsibility, ͏as͏ a TL͏S͏ ce͏rtificate provide͏s a͏ uni͏͏que identity ͏to each system, allowing anyone connectin͏g͏ to it to veri͏fy ͏they are communicating͏ with the in͏tended entity. 
  • It establishes a secure connection͏ that p͏re͏v͏en͏ts eavesdroppi͏ng, ensuring data inte͏grit͏y an͏d confidentiality. 

TLS certificates are all around us and every organization irrespective of their size use these certificates to secure communication both internally and externally. And as the organization grows, so does the demand for these digital certificates. This implies that the medium and large-scale enterprises are using thousands and thousands of TLS certificates, and each certificate is crucial for securing different servers.  

Consi͏dering a ͏Scenario (challenges of TL͏S certific͏ate) 

An͏ enter͏prise m͏an͏agin͏g thousa͏nds of TLS͏ server certificat͏es acros͏s numerous͏ w͏eb servers and netw͏ork devices f͏aces increasing challenges as͏ web tra͏nsactions grow. T͏o u͏nder͏sta͏nd and analyze t͏hese diff͏iculties, c͏onsider the fol͏lowing scena͏rios: 

Scenario Challenge Impact 
Expired ͏Certificates leading to Application Outage Keeping track of certificate expiry dates becomes daunting due to failures in proper installation or updating, lack of expiry notifications, or improper updates across load-balanced servers. Unnoticed expired Certificates leads to sudden application outages that cause users to lose access to essential services. For example, an e-commerce platform going offline could result in lost sales and damage to the company’s reputation. 
Security Risks from Improper Certificate Management Expired or improperly revoked certificates create security vulnerabilities. Malicious attackers can exploit these certificates to create counterfeit websites or intercept communications, which can lead to data theft, unauthorized access, and compromised data integrity. 
Delayed Responses to Security Incidents Decentralized certificate management hinders rapid updates in response to cryptographic vulnerabilities or CA compromises. Delays in updating compromised certificates increase organizational vulnerability and expose critical systems and data for longer periods. 
Complexity and Lack of Unified Policies Coordinating certificate management among multiple stakeholders and departments leads to inconsistent practices. Fragmented approaches result in uneven adherence to security protocols, increasing the risk of vulnerabilities and mismanagement. 
Underutilization of Automation and Technology Reliance on manual processes despite advancements in automation tools. Manual tracking of certificate expirations and deployments increases the risk of human error and inefficiency, limiting the organization’s capacity to scale its security measures effectively. 

Wit͏h͏ ͏a͏n understanding of TLS certifica͏tes,͏ their importance, and the associated challenges, now we will explore the best practices recommended by NIST that you can follow to enhance your certificate management process in your organization.

B͏est P͏ractices of NIST͏ SP 1800-16͏ 

We recomend organizations to esta͏͏blish a form͏al T͏LS͏ certificate mana͏gement prog͏ram that is supported by͏ executive leaderships, ͏and follow ͏with clear guidance and policies to a͏ddress these c͏hallenges head on. These key best practices include:

Establish Clear Policie͏s and Respo͏nsibilities

  1. Define ͏Roles ͏and Responsibil͏ities

    • Ce͏͏rtificate Owner: T͏he͏se are the individuals or teams responsi͏ble for the servers ͏and s͏ys͏t͏ems where ͏T͏͏LS certificates are installed. Often, these own͏ers might not be well-ver͏sed in the be͏st practices ͏for m͏anagin͏g TL͏S certific͏ate͏͏͏ te͏st. Therefore͏,͏͏ providi͏ng͏ them ͏with cle͏ar and specific requirem͏ent͏s is essential, and these should͏ be en͏forced ͏as orga͏nizatio͏nal policies. This helps ensure they understand their role in maintai͏ning th͏e security a͏nd function͏ality of the certifica͏tes while having all necessary tools and information to keep the certificate management process running as smoothly and as efficiently as possible.

      For Example͏: In the case of server’s certificate expiration, the certificate owner should have the necessary knowledge to know the steps to renew the certificate in a timeline prevent to make sure that there are no service interruptions or any security vulnerabilities that can negatively impact the organization in the long run.

    • Certificate Se͏rvices Team:͏ This team typically operat͏es ͏a͏t a cen͏tral le͏vel within͏ the organ͏ization and is responsible for issuing͏,͏͏ ren͏ew͏ing, and revocatin͏g TLS ͏c͏ertif͏icates. They provide ongoi͏͏ng support and e͏ns͏ure tha͏t all c͏ertificate manageme͏nt processes ͏are c͏onsistent an͏d secure.

      For Example: When the ͏certificat͏e se͏rvices team might͏ ͏͏implements automated ͏tools to monitor certificate expiration d͏͏ate͏s and initiate renewals automati͏͏cally, they minimize the biggest risk of human errors that leads to certificate expirations that reduces the risk of expired certificates that have catastrophic impact.

  2. Ow͏ner͏ship R͏equirements

    • We suggest assigning contact information to the functional groups in the organization. C͏ontact details for ce͏rtificate owners ͏should be assigned to functional groups, su͏ch as A͏ct͏ive Directory ͏(AD)͏͏ g͏rou͏ps. This helps to make sure that there͏ is al͏ways a designated͏ contact ͏person͏ or ͏͏team responsible ͏for the ͏ce͏͏rtificates.

      For Example: If ͏a ce͏rtificate o͏͏wne͏r l͏eaves th͏e org͏an͏iz͏ation or cha͏nges rol͏es, the͏ AD group sho͏ul͏d be u͏pda͏ted within͏ 30 business days to reflect the new ͏responsible͏ pe͏rson. Th͏is prevents any lapse in certificate manag͏ement duties due to personnel ch͏͏anges.

    • Update ͏Contact Informat͏ion Pro͏mptly:͏ The cont͏ent of the functional groups sh͏ould be updated promptly within 3͏0 bus͏iness days whenev͏er there is a r͏ol͏e͏ reassignment o͏r the termination o͏f an individual me͏m͏b͏er͏. This e͏nsures that t͏he͏ re͏͏sp͏o͏nsibility for ma͏͏nagin͏g TLS cert͏ificat͏es is always cl͏early assigned and up to d͏͏a͏te.

      For Example: When ͏an employee ͏r͏esponsible for certain certif͏ica͏tes leaves ͏the͏ company, the͏ir re͏placement͏’͏s contact inf͏orma͏tion should be updated to mai͏nt͏ain continuity in ce͏rtificate manag͏ement.

  3. C͏ertificate Validity an͏d Key Length

    • Set Maximu͏m Validity ͏P͏eriod: Certi͏ficates should have a maximu͏m v͏alidity per͏iod of one year o͏r le͏ss. This policy ͏ensu͏res that cer͏tif͏ic͏ates are reg͏ula͏rly updated, reducing the risk of being com͏promised over time.

      For Exam͏ple: S͏͏horter validity periods force regular͏ review and renew͏a͏l of certificates, ensuring they u͏se th͏e latest securit͏y standards and reduc͏ing the likelihood ͏of using outdated or vulnerable ͏certificates.

    • Ensure C͏ompliance with Key͏ Length Standards:͏ Certificates must use key lengths that͏ comply͏ with NIST ͏SP standards, such ͏as RSA with a minimum of 2048 bits and ͏ECDSA ͏with a minimum ͏of͏ 224 ͏b͏its. These standard͏s are set to ensure the cryptographic strength of the certificates.

      For Example: Using AES-256-b͏it k͏eys provides a considerably higher level of security͏ against brute forc͏e that are essential͏ for protect͏in͏g sensitive data transmitt͏ed over the network.

  4. Approved Signi͏ng Alg͏orithm

    • Use Approve͏d ͏Algorith͏ms and Has͏h Func͏t͏ion͏͏s: A͏l͏l certificates should be signed usi͏n͏g app͏rove͏d algorithms and hash functions, such as ͏SHA-256, as͏ specified by NIS͏T guidelines.

      F͏or Examp͏le: ͏S͏HA-256 is a widely acc͏epted hash function th͏at provides str͏ong crypto͏graphic security͏. Usi͏ng approve͏d alg͏o͏rithms ͏ensures that the certif͏i͏cates ar͏e against common attack vectors.

Auto͏mate Certificate Management

  1. Ma͏naging Cert͏ificate Invento͏ry

    • Imple͏ment a centr͏al certificate͏ m͏anagement service that includes automating the entire certificate lifecycle, such as issua͏nc͏e, renewal, and r͏evocati͏on. This s͏erv͏ice ͏should cover certificat͏e ͏discovery, inventory management, ͏report͏ing, monitoring, enrollm͏ent͏, insta͏llation͏, and renewal.

      For ͏Example: An or͏ganization uses a centra͏lized sy͏stem to auto͏ma͏tically issue and renew TLS certifica͏tes f͏or ͏all its web servers, ensuring cert͏i͏ficates͏ ar͏e always up-to-͏date an͏d reducing manual ͏management tasks͏.

    • System Integration:͏ Integrate the central certificate management service with͏ other enterp͏rise systems,͏ includin͏g identity and access mana͏gem͏ent, ͏ticketing systems, con͏figuration managemen͏t d͏atabases, ema͏il, work͏flow system͏s, and logging͏/a͏uditing tools.

      F͏or Exa͏mple: An organizati͏on that integra͏tes its certificate management system͏ with its identity and͏ access m͏͏an͏agement ͏s͏ystem can automati͏cally ͏issue ce͏rtificates͏ ͏for new app͏lications and track the͏m through͏ the ticketing system͏ for any ͏issues.

  2. Regularly Audit and Update Cer͏tifica͏te I͏nventory

    • Regular audits of t͏he certific͏ate inventory are essentia͏l to i͏dentify and address any discr͏epancies or issue͏s. This involves verifying the v͏alid͏ity a͏nd appropriateness of ͏each certif͏ic͏at͏e, ensur͏ing that all cert͏ific͏ates are c͏urren͏t͏͏, and identifying͏ any nearing expiration. Regular updates to the inventory help ͏mai͏ntain ͏its ͏accuracy and relevance, which i͏s c͏ritical for maintaining securi͏ty.

      F͏or Example: If an organization͏ find͏s e͏xpired certificates during a͏n a͏udit͏, it can quickly renew them to p͏reve͏nt͏ securit͏͏y breaches and ensure continuous protection.

De͏fine Terms of S͏ervice

  1. Serv͏ice Description

    • Outli͏ne͏ t͏he services p͏rovi͏ded, such as netwo͏rk͏͏ discovery, mo͏nitor͏ing enrollmen͏t, and automation.

      For Example: ͏An or͏ganization that off͏ers services lik͏e͏͏ a͏utomat͏ic netwo͏rk d͏͏iscovery, automated cert͏ifica͏te issuanc͏e a͏n͏d renewal, and continuous certi͏ficate m͏onitoring ensures ͏compliance͏ an͏d ͏maintains sec͏urity.͏ Detailed docume͏nta͏tion ͏is provided to outline eac͏h of the services fo͏r internal users.

  2. Responsibilit͏ies

    • Sp͏ecify the responsi͏bilities of bo͏th certific͏ate ow͏ner͏s and ͏the Certi͏ficate Services team, ensuring ͏clear expectations͏ a͏nd coop͏eration.

      For Exam͏ple: The Cert͏ificate͏ Services team handles the iss͏uance and renewal͏ of certificat͏es, while individ͏ual business units mus͏t ensure the͏ir͏ system͏s are acc͏essible and that updated c͏ontact infor͏m͏a͏tion is maintai͏ned.

  3. Service Level Agreements͏ (SLAs)

    • Define expected ͏service ͏levels a͏nd SLA respo͏nse times to se͏t clear expectat͏ions for service delivery.

      For Exam͏ple: An͏ organization͏ ͏͏guarantees ͏a 24-hour͏ turnarou͏nd for i͏ssuing new certi͏ficates,͏ 48 hour͏s for renewals,͏ ͏and ale͏rts within 1 hour for ce͏rtificate i͏s͏s͏ue͏s, ensuri͏ng timel͏y͏ and͏ r͏e͏liable service.

Conduct Regular Audits

  1. Period͏i͏c Reviews

    • P͏erf͏orm regu͏lar audits of TLS certi͏ficate͏ managemen͏t practices to en͏sure ͏pol͏icy compliance. ͏Verify that all certificate owner͏s maintain a current ͏i͏nventory of͏ th͏ei͏r certificate͏s a͏nd ͏follow the necessar͏͏y steps to include͏ a͏l͏l c͏erti͏fy͏͏cates͏ in the͏ inv͏entory.͏

      For Exam͏ple: Organizations that pe͏rf͏orm quarterly au͏dits benefit from maintaining accurate inventory of their TL͏S certificates that in terms helps to adhe͏r͏e͏ to͏ t͏he organizatio͏n’s ce͏rtificate mana͏gement policies͏.

  2. C͏ompliance Ve͏rificatio͏n

    • Auditors should confirm that the Certifi͏cat͏e servi͏c͏es tea͏m provides the ne͏cessary suppo͏rt fo͏r certificate owners to c͏omply with policies. Regular audits ͏͏help prevent unexpected operational outa͏ges and s͏ecurity bre͏aches by ide͏ntifying ͏a͏nd addressing latent risks͏͏ associated with T͏LS certificates.

      For͏ exam͏ple, During annual͏͏ ͏audi͏ts, a͏n a͏uditor͏ ͏verifies tha͏t the Certificate servi͏ce͏s͏ team effectively͏ supports certificate owne͏rs, ensuring c͏omplian͏ce wit͏h security protocols ͏and pr͏ev͏enti͏ng pot͏ential operational͏ disruptions or security͏ breaches.

By ͏following͏ these best prac͏tices, o͏rganizations can est͏ablish a secure͏ and efficient TLS cert͏i͏fi͏cate management program, ͏en͏suring their c͏ert͏ifica͏t͏e͏s rema͏in͏ a ͏security asset rather th͏an a li͏ability.

How to Automate F5 Certificate Management with CertSecure Manager

Whether you’re running a small business website, a complex enterprise application, or a cloud-based service, your users expect seamless, uninterrupted access. This is where load balancers come into play, and among the most trusted names in this domain is F5 Networks.

But manual certificate management on an F5 device can be pretty hectic considering the lifespans of SSL/TLS certificates were a couple of years long, until recently. The SSL/TLS certificate life is getting shorter and shorter. With the CA/Browser Forum mandating certificate lifecycles of just 47 days, organizations must adapt to this dramatically accelerated renewal cycle to maintain continuous security and compliance. The burden of this drastic change on manual management is substantial. Consider the amount of effort an IT team would have to do to manage hundreds of certificates that are quickly coming up for expiration. Missed renewals run the ongoing risk of causing additional disruptions.

The Hidden Risks of Expired Certificate Revocation Lists (CRL)

Digital certificates play a crucial role in web security and public key infrastructure, ensuring secure internet communication. These certificates act like digital identifications that verify a website’s legitimacy. Now, consider a scenario where you try to access a website, but unknown to you, the certificate validating this site has been compromised. This oversight opens a back door for hackers to intercept your sensitive information.

To address such risks, every certificate has a finite validity period during which it is considered as trusted. However, during this time, situations may arise where the owner or the Certification authority that issued the certificate may declare it as untrusted. For example, if the private key of the certificate is compromised or if the owner of the certificate no longer controls the domain for which the certificate was issued, then the certificate becomes a liability. 

In such case the untrusted certificate is revoked and the certificate users are informed about the revocation. This is done by adding the given certificate to a Certificate Revocation List. A CRL is simply a blacklist managed by the CA that lists the certificates which should not be trusted and are no longer valid.  Although these CRLs maintain trust in the PKI infrastructure, an expired CRL can present us with hidden risks and challenges that can undermine this trust. 

Working of CRL

CRL is the only way for the PKI to know whether a certificate has been revoked before its expiry. While PKI provides a list of trusted users through issued certificates, it is also very important to know the ones who are no longer trustworthy. CRL serves this very purpose by listing the certificates revoked before expiry. 

Steps involved in CRL are as follows: 

  • Request Initiation

    The entity that has been issued the certificate, detects that the certificate needs to be revoked that could be due to compromise, misuse, etc. sends a revocation request to the issuing CA. This request typically includes the certificate serial number and the reason for revocation.

  • Revocation Request Process

    Then, the CA verifies the authenticity of that revocation request and once the request is validated, it marks the certificate as revoked in its internal records.

  • List Updating and Signing

    After that, the CA adds the revoked certificates to the list and updates the CRL. The integrity of the revised CRL is then verified by having the CA’s private key sign it.

  • CRL Publication

    The signed CRL is published and made available to the public and other entities that rely on the certificates issued by the CA. This is done through various methods, like publishing on a web server, distributing via LDAP.

  • CRL Distribution

    Browsers, servers verify the status of certificates by periodically downloading the CRL from the specified location.

  • CRL Usage

    Now when any browser or server encounters a certificate it checks its serial number against the downloaded CRL. In case the certificate is found in the CRL it is considered as revoked.

How to View the Certificate’s Revocation Status 

The Certificate revocation list is made available by the Certification Authority at a specific distribution point, also available with the certificates. 

If you have the digital certificate downloaded then you can open it or if it’s the certificate with a website then click on the PADLOCK icon next to the URL and follow the given steps: 

  1. Click on connection is Secure and then Certificate is valid button.
  2. Go to the details section and scroll down to CRL Distribution Points (CDP).
  3. You will see one or more URLs pointing to the location where the CRLs are published.
  4. In the field value, copy the URL and paste it into the search bar.
  5. The browser will download the CRL file. You can access it to check the revocation list info.

Risks Of an Expired CRL

Security Risks: Accepting a Revoked Certificate 

If a CRL is outdated or expired, systems that are relying on it may not be aware about the recent revocation updates. This would mean that a compromised or an invalid certificate could be accepted by the systems trusting it and would lead to a vulnerability waiting to be exploited by hackers. 

Operational Risks: Service and Compliance Issues 

Many of the applications and servers are hardened to always check for the CRL before accepting the certificate. Now if the CRL is expired, these machines, might just reject the certificates automatically, leading to outages and interruptions. Regulatory standard often mandate to use an up-to-date CRL. Non-compliance to the standards might lead to financial losses to the organization. 

Trust and Revenue Risks

If a server is unable to reliably verify the status of a digital certificate, it risks the trust in digital communication and leads to revenue losses for the organization as users and systems can no longer be completely sure about the integrity of certificates. 

Mitigating the Risks with CertSecure Manager

To mitigate and monitor these risks, CertSecure Manger offers PKI health view to pre detect and monitor such failures. Following is the detailed explanation on how CertSecure Manager helps in resolving these complications: 

CertSecure performs a detailed check of all the Certification authority components and showcases all the CDP, AIA along with the remaining days for the Certificate revocation list. If a failure is detected, the solution automatically alerts the admins about the issue.

  • Detailed Check: CertSecure verifies all the certification authority’s components and provides a centralized view for the PKI health.
  • CDP, AIA points: It identifies the Certificate Distribution Point (CDP) and Authority Information Access (AIA) points for locating the CRL.

Your Guide For The 90 Day Digital Certificate Shift

SSL/TLS certificates are essential for establishing trust and securing internet communications. An SSL/TLS certificate confirms the identity of the website you are visiting. It confirms that you’re actually connecting to the intended website and not a fraudulent one designed to steal your information. 

When a user visits a website secured with a valid certificate, their browser can verify the website’s identity. This verification assures users that they are on a legitimate website, not a fake one designed to steal their information (phishing). These certificates act as a security lock on your website, and just like any other lock, they don’t last forever.

These have an expiry date and require a regular check and monitoring system. Expired certificates trigger browser warnings, harming user trust and potentially impacting SEO rankings, user abandonment, data breaches, and reputational damage. 

In the past, managing SSL/TLS certificates was a very hectic and time-consuming process, which included using spreadsheets and calendar reminders. Lately, there’s been a buzz around reducing the lifespan of these certificates from the usual year (398 days) or so to just 90 days. This blog will help you understand the 90-day certificate, why they’re being considered, and what it means to you and your organization. 

Journey Towards Shorter Validity Period  

The validity period of SSL/TLS certificates has undergone a significant transformation, driven by the evolution of cybersecurity threats and the ongoing quest for stronger web security. 

In the early days of the internet, certificates had lifetimes as long as ten years and obtaining a certificate may have actually required an in-person visit to the Certificate Authority’s premises! Then as internet practices grew, the CA/Browser Forum (CAB Forum) was established to standardize certificate practices and enhance web security.

Their overall mission is to work on the best practices of issuing and managing digital certificates together and one of their key efforts in this regard has been to continuously reduce the maximum validity period for certificates. 

By the year 2016, the maximum validity period was reduced to 3 years, and by 2018, it was reduced to 2 years (730 days). It wasn’t until 2019 that an attempt was made to shorten the validity period to 1 year (398 days) by Apple. Apple’s proposal highlighted the growing concern about the risks associated with longer validity periods of these certificates and pushed the CA/Browser Forum to re-evaluate existing standards of shorter validity periods.

This proposal was not passed by the Forum but in 2020, Apple shifted to 398-day SSL validity certificates in the Safari Browser and in the late 2020, this validity period of 398 days was officially enforced. 

Early in 2023, Google announced plans to potentially require websites to use SSL/TLS certificates valid for only 90 days. While this proposal has not yet been accepted, just like Apple, Google could also mandate the use of 90-day certificates for its Chrome browser, and as it covers 62% of the market share, such implications could lead to set industry standards and regulations in the future. 

Why is 90 days considered the ideal number for SSL/TLS certificates?

There has not been a definite answer to the appropriate validity period for SSL/TLS certificates, but a key advantage of shorter lifespans is the reduced window of vulnerability if a certificate is compromised. If a hacker gains access to a certificate with a 90-day validity, they have a much smaller window to exploit it before it expires and becomes useless. 

The 90-day proposal represents a middle ground between robust security and a manageable workload, as it provides sufficient time for renewal with a perfect validity period for a certificate. While shorter validity periods like 30 days offer even stronger security, 90 days or three months is the sweet spot, as anything less could become a hassle, especially for businesses and people who are not using a certificate lifecycle management solution and managing hundreds of websites.

For instance, during a sales season, if an e-commerce website uses 1-month certificates, they would need to start the renewal process every 30 days or less along with managing huge customer demand, and if they miss or forget the renewal date for any certificate, it will cause them huge losses during peak season. 

In practice though, the actual time of renewal of a certificate will be considered to be 60 days due to the buffer time if 90 days were to be official, meaning replacing your certificate 6 times every 12 months. Hence, 90 days allows for frequent updates without overwhelming website owners, particularly those with smaller setups. 

How can a Shorter Validity Period help your Organisation? 

The industry’s push towards 90-day TLS certificates is driven by a compelling combination of factors, all focused on enhancing online security. Around 60-70% of digital certificates have a validity period of more than 90 days, and automated systems have also supported quick renewal of these certificates.  

  1. Reduced Damage from Key Compromise

    Reduction in the validity period of the certificate will help in preventing cyber threats. If a private key is compromised, attackers will have limited time to impersonate your website and intercept your organization’s sensitive data. For instance, an e-commerce website experiences a data breach, potentially compromising its private key.

    With a 90-day certificate validity, the damage from stolen customer information is limited as the attacker only has three months to exploit it before the certificate expires. This allows the website to revoke the compromised certificate and issue a new one much faster, further mitigating the risk.

  2. Faster Adoption of Stronger Cryptography

    Shorter validity periods necessitate more frequent key generation, which will allow your organizations to adopt new and stronger cryptographic algorithms as they become available, enhancing overall security. Frequent key generation ensures that even if an attacker manages to crack a specific key, they’ll only be able to access a limited amount of data for a shorter period.

    For instance, if a new, more secure cryptographic algorithm is developed, an organization using 1-year certificate validity might wait until the next renewal to adopt the new algorithm. However, shorter validity periods necessitate more frequent renewals, prompting a faster adoption of stronger cryptography as new certificates are issued.

Impact on Businesses when manually managing 90-day certificates 

With the proposed shift towards 90-day certificates, managing security is about to get even more critical. Businesses are increasingly migrating to cloud-based platforms and applications, which necessitates a growing number of certificates for secure communication channels. Now that the internet is rapidly expanding, billions of smart devices connecting to the internet often require their own unique TLS/SSL certificate to ensure secure communication. 

While some organizations may be tempted to stick with traditional, manual methods for certificate lifecycle management (CLM), this approach carries significant risks that can substantially impact businesses when handling 90-day certificates. A manual certificate lifecycle leads to possible outages, leaving your businesses vulnerable and scrambling to recover.

These outrages can cause huge financial losses for your organization and affect your image in the eyes of your users. According to an article published by Pingdom, nearly all businesses (98%) report that even a single hour of website outage can cost them more than $100,000.  

In the IT industry, every minute a system is down translates to a significant financial loss. While the average cost is $5,600 per minute, companies can lose anywhere from $145,000 to $450,000 per hour, depending on their size. For instance, if we consider 3 outrages per year on average and an average downtime of 4 hours with a $5,600 per minute cost, the annual cost to the business can reach around $4 million.

Impact on Businesses when using Automated Certificate Lifecycle Management Solutions for 90-day certificates 

As traditional and manual practices seem easy, integrating an automated Certificate Lifecycle Management (CLM) solution for the 90-day certificate can offer significant business benefits. To eliminate human error, missing documentation, or any such practices that could result in catastrophic outcomes, organizations require a strong automated solution to administer their SSL/TLS certificates. 

According to a report by Verified Market Research, the Certificate Lifecycle Management (CLM) software industry is experiencing rapid expansion, fuelled by the rising number of TLS/SSL certificates organizations need to manage. The market size in 2023 was estimated at 3.5 billion US dollars. By 2030, this figure is expected to reach a staggering 9.5 billion US dollars, reflecting a compound annual growth rate (CAGR) of 21.58%. 

The exponential growth of certificates due to 90-day lifespans puts a strain on manual methods. A CLM solution such as CertSecure Manager will provide automated renewals to minimize the window of vulnerability where attackers can exploit gaps in encryption while streamlined revocation processes allow businesses to quickly address security threats and minimize potential damage. By automating tedious tasks and centralizing management, businesses gain improved efficiency, allowing IT staff to focus on more strategic initiatives. 

Automating the certificate lifecycle for a 90-day certificate also helps to curb expenses for manual management, including costs due to labor and the possible financial repercussions from outages and security breaches.

These solutions also aid in compliance with industry standards, avoiding liabilities and fines, and can scale to cater to the new demand of hundreds if not thousands more 90-day certificates that could come about from the increasing digitization of more services and devices. The exponential growth volume places a strain on vulnerabilities of manual management systems, making security a lousy technique to fight exposing your organization. 

Best Practices for managing 90-day certificates using Automated CLM

The answer to this time-consuming problem of manual certificate management of 90-day certificates, of course, is a Certificate Lifecycle Management (CLM) solution, which provides an efficient way to automate certificate workflows using powerful machine-driven capabilities, etc.

If you want to get the most from these, then best practices are key to realizing the full potential automation can offer. Consider these strategies to maximize the automation of CLMs to achieve efficiency and security benefits. 

  1. Policy

    Ensuring that TLS/SSL certificates have a 90-day lifecycle than the default allows the industry standard to improve security; consequently, lowering the risk of exposure can be leveraged is a good practice. A good policy consists of regulations that describe how to request, approve, or rotate the 90-day certs in different ways (need to keep this automated to reduce human failure).

    It should also define ownership for managing the 90-day certificates and bring accountability as well-regulated adherence. The exception-handling steps and escalation process should also be straightforward for any variances from the norm.

    For instance, an e-commerce website that processes sensitive customer data, such as credit card information, should prioritize strong security. Any exceptions to the 90-day lifecycle, such as a critical certificate for a legacy application, would require documented justification and approval from senior management.

  2. Reports

    An automated CLM system for a 90-day certificate should be able to output a report detailing crucial information for your organization’s existing TLS/SSL certificate. Regularly maintaining and updating this report means that you can stay informed and know if any expiration actions are required so that you do not miss out on renewals and, therefore, will stop being exposed to the latest security risks to your organization.

    For instance, an organization’s CLM report on a 90-day certificate might generate information such as Certificate Name, Issued By, Issued Date, Expiry Date, Days Remaining, and respective Domain.

  3. Provision

    In order to deal with the more frequent renewals that come with the shorter certificate life, such as 90 days, some automatic provisioning is necessary. Use an automation system wherever possible to manage your 90-day certificates and integrate them with the Certificate Authority (CA) through protocols such as ACME (Automated Certificate Management Environment).

    Reducing the chance of you having an expired certificate is a win, streamlining your deployment process is a win, and making sure that the same practice is in place across all systems wins the prize. This also liberates IT resources to devote energy to more strategic work, increasing the overall efficiency and security of the internet.

  4. Find

    To ensure that you have taken the necessary steps, your first step should be to discover and inventory all TLS/SSL certificates throughout the entire organization. Run automated discovery tools across your network and discover every single cert in use.

    This comprehensive inventory should be stored in a central certificate management system to form the single source of truth for every digital certificate throughout an organization. Maintenance allows you to check those certificates often, so none expires without anyone noticing.

    For instance, a hospital network with public-facing web servers for patient portals and internal servers for electronic health records (EHR) systems might require its own TLS/SSL certificate to secure communication. An automated discovery tool can be deployed to scan the network and uncover all active certificates on these domains.

  5. Monitor

    Automatically monitor your 90-day TLS/SSL certificates to ensure they remain secure and compliant as part of your continuous monitoring workflows. Use monitoring that generates real-time alerts if any of these issues are detected, for example, impending expiration or revocation of a 90-day certificate and/or an incorrect configuration.

    Also, a dashboard providing an organization-wide overview of certificate health status can give administrators immediate feedback to quickly identify and resolve issues. Scheduled reporting and alerts mean problems can be dealt with before they impact the quality and security of your network.

    For example, a cloud-based e-commerce platform relies on numerous 90-day TLS/SSL certificates to secure communication across various services, such as the customer portal, payment processing systems, and internal APIs. A robust monitoring solution can be configured to provide real-time alerts for critical events, including certificate expirations, revocation, and configuration issues.

  6. Control

    The certificate lifecycle is a process ranging from ordering the digital 90-day certificate issuance, installation & activation upon its delivery, and then finally, when it expires, undergoing renewal again.

    Restricting the service that can request, issue, and manage these 90-day certificates protects against mismanagement by limiting changes to those permitted only and authorized personnel performing specific tasks using role-based access. RBAC can be used to enforce separation of duties, where different individuals are responsible for requesting, approving, and issuing certificates.

    Regulations should be reviewed and taken into consideration in case of a change in the organizational structure and/or security policies. Regular audits and feedback in the certificate management process reinforce compliance, leading to ongoing improvement and best practices alignment for these 90-day certificates.

By following these best practices, you can effectively organize a 90-day TLS/SSL certificate, enhancing your security status and reducing the risk of certificate-related incidents. 

What happens if you use Expired Certificates? 

SSL/TLS Certificates protect website integrity and securely transmit information. So, what do you suppose occurs when a certificate slips your mind, or even worse, one falls off the radar with an expiry date well past, especially in the case of 90-day certificates? The results could be annoying users seeing giant block-based error messages to uncountable entry points that can lead to security issues.

In the year 2017, Equifax faced a massive data breach exposing the sensitive information of over 147 million Americans. One contributing factor to the breach was an expired digital certificate that prevented Equifax from inspecting its traffic for suspicious activity. This lapse in security allowed hackers to remain undetected within the network for an extended period, ultimately leading to data theft.

  1. Data Breaches

    A Legitimate SSL/TLS authentication provides the safe route to preserve exclusive statistics like your login credentials, credit card information, and a person’s related content from being considered by someone else.

    When this certificate loses its integrity, the tunnel collapses and provides an opening for hackers to step in and intercept your data as it moves on another side. Picture a hacker listening in on your online banking session — an unexpired certificate could allow this, which might end up in huge financial losses and identity theft.

  2. Reputation Damage

    An expired SSL certificate says to your users “We don’t care about security”. Negligence like this can often ruin a marketing budget or damage a corporate name. Just imagine how much trust this would break with you users when a website has to admit that it allowed for such an embarrassing security vulnerability to happen.

  3. Search Engine Penalties

    Search engines such as Google are sensitive to protecting users and reward higher rankings for using SSL/TLS certificates. Sites using outdated certificates get marked as unsafe, which can see their ranking on search go way down. This reduced visibility means less traffic, leading to lower web visits and, eventually lesser brand reach.

  4. Service Interruption

    Since the certificate has expired, browsers recognize this and display warning messages, preventing your users from having access to your website.

    For e-commerce businesses, that can be a loss of sales; for your users, it can lead to an unsatisfying experience; and for anyone who tries to access your site, this just adds frustration. Therefore, downtime due to Service Interruption can be a real problem and have a significant impact, especially for businesses that rely on online traffic and audience.

How can the CertSecure Manager solution help in managing these certificates?

If you only had a few SSL/TLS certificates in the past, it didn’t seem too difficult to manage using spreadsheets and manual renewals with calendar alerts. However, in the changing phases of the virtual world, websites are rapidly replaced with a large set of certificates, especially for different applications and subdomains. 

Trying to negotiate our way through countless dead certificates, lost renewals, and mistakes by humans is a nerve-jangling act. And that is when modern Certificate Lifecycle Management (CLM) solutions come to the rescue.

CertSecure Manager solution adheres to the required industry standards and regulations, which provides you certificate visibility & discovery in one centralized system, manages large-scale certificates, and helps your organization to save time & resources.

  1. Automated Renewal

    CertSecure Manager automates the whole renewal process -from generating renewal requests to ordering it from the Certificate Authority (CA) and installing the renewed certificate. It removes manual work, saving the IT team a lot of time and resources.

    All the time-consuming procedures that cause headaches have been eliminated, thereby facilitating your organization’s multiple renewals in short intervals, like 90 days. Studies note that 83% have had issues with certificates at least once in the past 12 months, and more than half (50%) reported incidents of compromised SSL/TLS certs.

    The system allows automatic replacement of certificates for applications such as IIS, Apache, and Tomcat webservers, as well as load balancers like F5, to make the turnover process quick and smooth.

  2. Discovery and Inventory Management

    CertSecure Manager performs a full scan of your IT infrastructure and handles all SSL/TLS, which removes the blind spots that can result in renewals being overlooked and perhaps enabling security vulnerabilities.

    You have a central place to manage all your SSL/TLS certificates and see the status, dates of validity, and ownership behind it all. This central point of knowledge allows for an educated route to be taken with regard to certificate management strategies.

  3. Alerts and Reporting

    CertSecure Manager doesn’t wait for certificates to expire before taking action. It generates proactive alerts notifying IT teams of upcoming renewals, allowing them to plan and prioritize tasks effectively. This allows it to generate detailed certificate health reports, upcoming renewals, and potential security risks, especially with 90-day certificates.

    These reports provide IT professionals with the information needed to improve certificate management practices and drive decisions based on data. It has an alerting system that sends notifications when a certificate is getting close to expiring or any other need-to-know update.

  4. Integration with DevOps

    It works with popular Certificate Authorities, DevOps tools, and automation frameworks and can be easily integrated into any deployment pipeline. This simplifies not only the certificate lifecycle management process for your existing IT ecosystem but also reduces the effort to transfer data between different systems.

    It simplifies operations, reduces errors, and supports an optimized management flow of certificates. CertSecure Manager integrates with your DevOps tools of choice within your organization, enabling certificate deployments during your CI/CD pipeline. This will automate the process of provisioning certificates on new environments.

With CertSecure Manager, you can effortlessly manage and secure your digital certificates, ensuring that your organization’s sensitive information remains protected while complying with regulatory standards. 

Conclusion 

The proposed move by Google towards shorter 90-day validity periods for SSL/TLS certificates presents a unique opportunity. While the proposal has not yet been accepted but it may necessitate adjustments, which underscores the importance of robust certificate management practices.

This includes adopting best practices for automation using a CLM solution such as Encryption Consulting’s CertSecure Manager to help organizations not only manage this shift comfortably but, in turn, capitalize on the many advantages that are going to come because of this change in shorter validity periods. 

CertSecure Manager provides full automation of the certificate lifecycle from discovery and inventory through issuance, renewal, and revocation. This simplifies the workflow, reduces mistakes, and ensures that always all available certificates are renewed, even with shorter validity periods.

While shortening certificate lifespans can be tricky and requires careful handling to avoid issues, the benefits, like stronger security, better compliance, and increased adaptability, outweigh the challenges. Therefore, given the need for automated certificate management, CertSecure Manager allows you to confidently lead the future of online security and can thus deliver real business benefits from a secure, centralized certificate management system. 

What is Certificate Lifecycle Management

Organizations need a strong foundation for the WPA2-Enterprise network, and to achieve that, deploying digital certificates should include a Certificate Lifecycle Management solution. Certificate Lifecycle Management systems, also known as Certificate Management Systems (CMS), provide support for using X.509 digital certificates for authentications. CMS allows admins to properly manage and control every part of an individual certificate by maintaining a broader perspective on the network state.

Certificate Authority

CA is one of the most important pillar of PKI. CA is a highly trusted entity which has been given this responsibility of signing and generating digital certificates. We’ll talk about digital certificates in the upcoming part. Also the CA undergoes a set of rules to ensure the integrity of certificates. Before issuing a certificate, CA first examine the records and documentation from official sources to ensure that the business is authentic, after that only it issues a digital certificate. A certificate authority performs three major tasks:

  • Issues certificates
  • Certifies the identity of the certificate owner
  • Proves the validity of the certificate
CA Hierarchy

As you can see in the above diagram, there is a proper hierarchy of CAs, while each has it’s unique role and importance in PKI architecture. There are generally 3 types of hierarchies: one-tier, two-tier, and three-tier.

Let’s discuss about each entity involved in the above diagram:

Root CA

Root CA is at the topmost level of the hierarchy. It is responsible for issuing and signing certificates for intermediate or subordinate CAs, which eventually can issue certificates for end entities like computers, users or services as seen in the above diagram. Due to its importance in the PKI infrastructure, the private key of the Root CA is kept highly secure in any organization, most of the times offline to protect against compromise. They usually have long lifespan, often 20 years or more. However they need regular renewal before they expire to maintain the trust chain.

Subordinate CA

Subordinate CA lies between Root CA and End-Entity Certificates and act as intermediate between them. What we mean by this statement is, they receive their own certificates from the Root CA and can issue certificates to user, devices or other entities. All the certificates issued by this Subordinate CA form a chain of trust that ultimately links back to the Root CA. Now this trust of chain has importance because while validating a certificate, this chain is checked only to ensure that the certificate is valid and trusted.

End-Entity Certificates

As already discussed in the Subordinate CA, these are the final issued certificates from CA. They do not issue certificates to other entities and therefore lies at the bottom of the certificate hierarchy. These certificates are installed on servers, machines and other devices. It’s simple use case can be SSL/TLS Certificate which is used to establish  a secure connection between the user and browser, ensuring data privacy and integrity.

How Does a Certificate Authority Work?

The process for getting a certificate authority to issue a signed certificate is explained below:

  1. The requestor or client creates a key pair (public and private key) and submits a request known as a certificate signing request (CSR) to a trusted certificate authority. The CSR contains the public key of the client and all the information about the requestor.
  2. The CA validates whether the information on the CSR is true. If so, it issues and signs a certificate using the CA’s private key and then gives it to the requestor to use.
  3. The requester can use the signed certificate for the appropriate security protocol.

Digital certificate

Digital certificate is a type of file or some electronic password that is used to prove the authenticity of a system using techniques of cryptography and PKI. It helps organizations to ensure that only trusted devices or users can connect to the network. Another use is to confirm a website’s authenticity to a web server, known as a Secure Socket Layer (SSL) certificate.

A digital certificate contains credentials like the user’s name, company, and a device’s Internet Protocol (IP) address or serial number. It includes a copy of the Public Key from certificate holders, which must be matched to a private key to compare and verify its authenticity. A Public Key certificate is then issued by Certificate Authorities (CAs) to sign the certificates and verify the credentials of the requested device. The information contained in a certificate is:

  • Subject

    Provides the name of the computer, user, network device, or service that the CA issues the certificate to.

  • Serial Number

    Provides a unique identifier for each certificate that a CA issues.

  • Issuer

    Provides a distinguished name for the CA that issued the certificate.

  • Valid From

    Provides the date and time when the certificate becomes valid.

  • Valid To

    Provides the date and time when the certificate is no longer considered valid.

  • Public Key

    Contains the public key of the key pair that is associated with the certificate.

  • Signature Algorithm

    The algorithm used to sign the certificate.

  • Signature Value

    Bit string containing the digital signature.

Importance of Digital Certification

Digital Certificates can be requested by organizations, individuals, and websites. A public key is provided through a signing request to validate the information. Upon Validation by a trusted CA, the data is signed by that CA with a key that offers a chain of trust to the certificate. This process enables the certificate to verify the authenticity of a document, authentication, or provide proof of a website’s credentials. 

Types of Digital Certificate

Digital certificates can be of different types, and those are:

  • Transport Layer Security (TLS/SSL) certificate

    A TLS/SSL certificate is used on a server to ensure that the communication with its client remains encrypted and private by providing authentication for the web server to send and receive encrypted messages to clients. TLS/SSL certificate comes in three forms:

    • Domain Validated

      This is a quick validation method acceptable by any website, cheap to obtain, and can be issued within a minute.

    • Organization Validated

      This helps provide light business authentication and is best choice for organizations selling products online.

    • Extended Validation

      This offers full business authentication to deal with large organizations’ sensitive and private information. It is generally used by businesses in the financial industry to offer authentication, trust, and security.

  • Code Signing Certificate

    It is mainly used to confirm the authenticity of internet downloaded files or software. Mainly used by developers to provide software available on third-party sites and have these files or software is not tampered with. The developer or publishers need to sign so that users know this software is genuine and can be downloaded.

  • Client Certificate

    This certificate is used to identify an individual user to a different user or machine or one machine to another. In an email, a sender signs a communication digitally while the recipient verifies its signature. This can also be used to help access protected databases

Benefits of Digital Certificate

Digital certificates are essential as cyber attacks continue to increase in volume and sophistication. A few crucial benefits of Digital certificates are:

  1. Security

    Digital certificates are responsible for encrypting internal and external communications to prevent attackers from stealing or intercepting sensitive data. For example, a TLS/SSL certificate helps encrypt data between a web browser and a web server to ensure that an attacker cannot intercept website visitors’ data.

  2. Scalability

    Digital certificates give businesses of all shapes and sizes with the same quality encryption. These are highly scalable, meaning that they can be easily revoked, issued, and renewed to secure user devices and are then managed through a centralized platform.

  3. Authenticity

    Digital certificates are vital to ensure online communication’s authenticity to prevent cyber attacks in this age. These ensure that a user’s messages are always sent and reach the intended recipient. A few use cases are document-signing certificates for digital document signing, TLS/SSL certificates encrypting websites, and Secure/Multipurpose Internet Mail Extensions (S/MIME) encrypt mail communication.

  4. Public Trust

    Using a digital certificate ensures that a website is authenticated and genuine and that documents and emails are adequately authenticated. It also reflects public trust by assuring clients that they are dealing with a genuine company concerned with security and privacy.

  5. Reliability

    Only those CAs can issue digital certificates which are publicly trusted. One needs rigorous vetting to ensure that attackers cannot trick victims that use a digital certificate.

What is the difference between Digital Certificate and a Digital Signature?

A digital certificate is a file that is used to verify the identity of a user or a device and enables connections that are encrypted in nature. At the same time, a digital signature is a hashing approach that uses numeric strings to validate identity and provide authenticity. A cryptographic key is used to fix a digital signature to a document or an email, this signature is hashed, and when the recipient receives it, the same hash function is performed for decrypting the message.

Why is Certificate Lifecycle Management important?

Digital certificates are built using public key cryptography, a type of asymmetric cryptography where both parties (sender and receiver) have half of a public-private key pair. Each side uses its half to encrypt the communications, which the holder of the second half can decrypt. This type of cryptography is better than hash cryptography, which is generally used in credential-based systems but requires more steps.

Due to its asymmetrical nature, it requires two parties to establish secure communications to provision the public-private key pair. This usually happens through the mutual trust of a CA. A robust Certificate Management System (CMS) is an essential tool for managing the lifecycle of a certificate. This CMS allows a user to view, manage and customize all process aspects.

The Stages of a Certificate Life Cycle

Digital certificates are issued and confirmed by a CA to authenticate an identity. Passwords rely on phrases or words created by a human, the user. But certificates utilize public-private key encryption to encrypt information and are authenticated using Extensible Authentication Protocol TLS (EAP-TLS), one of the most secure authentication protocols. EAP-TLS is defined in RFC 3748, which provides support for multiple authentication works.

Certificates offer more advantages because these are easier to use and more secure than credential-based authentications. Most IT security firms (almost 55%) prefer a method of protecting accounts and authenticating them without involving passwords. However, certificates have an expiry, too, and are not valid forever, and their lifecycle is based on an organization’s preferences.

The stages of a certificate are:

  • Certificate Enrolment
  • Certificate Distribution
  • Certificate Validation
  • Certificate Revocation
  • Certificate Renewal
  • Certificate Destruction
  • Certificate Auditing

Certificate Enrolment

Certificate Enrolment is the first phase of the certificate cycle, which typically begins with a user or a device requesting a certificate from a CA. This request consists of a public key and other enrolment information. Upon receiving a request for the certificate, the CA verifies information based on the advanced set of rules. If the information gets authenticated and is legitimate, the CA creates the certificate and another certificate for requesting party to identify it. There are four steps required for certificate enrolment:

  • Request a Certificate

    A certificate enrolment process starts when a user requests a certificate enrolment with a CA. This request should consist of enough information to enable the CA to verify the user’s identity. The information needed is domain name, business telephone number, which is obtainable via public sources, and three contacts – authorization, technical, and billing. The CA can also ask for additional information depending on the type of certificate requested.

  • Add required Characteristics

    Before submission of the relevant information (in the above step) is completed, the user also needs to submit other details like sending over their public key for the CA’s signature, the hashing algorithm, and the digital signature to create the digital signature using it. This public key, along with a private key, is created by Cryptographic Service Provider (CSP) after receiving the certificate request and passing it to the CA.

  • CA validates request

    After receiving the enrolment request, the CA uses a public key to decrypt the digital signature, calculates a hash, and verifies the hash in the decrypted signature. It also uses all the given verification information for validation purposes. If Validation is successful, the CA digitally signs the public key and sends this completed certificate to the user.

  • Install the certificate on the user’s machine

    After verification is completed, the user needs to install it on the server and take note of its destination. Users should also copy the file received from the Certification and store the certificate’s relevant keys in a secure location. After these, users should publicize copies of their certificates to websites and web browsers for authentication.

Certificate Distribution

Certificate Distribution happens when the CA distributes the certificate to the user. This is a separate process because it requires management intervention from the CA. The CA sets policies that affect the use of the certificate in this stage.

Although CA Client Automation does not provide any automated certificate distribution technology, it comes with default certificates for each CA Client Automation node and application-specific certificates. To migrate from the default certificates after an install which was the default, the certificates should be distributed in the following ways:

  • Create a new root certificate and ensure the root name differs from the existing CA Client Automation root certificate.
  • Schedule the distribution of this new root DER encoded certificate within CA Client Automation infrastructure’s all nodes.
  • Create new security profiles in the CA Client Automation management database to replace existing profiles of an application-specific certificate.
  • Schedule the distribution of new certificates to all CA Client Automation nodes.
  • After successfully distributing the certificate, the previous CA Client Automation certificates must be deleted.
  • Delete the old security profiles used for the application-specific certificates.

Certificate Validation

When a certificate is used, the current status of a certificate is checked to verify whether it is still valid or not. There can be certain circumstances like compromise of private key or CA, security policy violations etc. which may cause a certificate to become invalid or get revoke before its natural expiration. Here what CRL plays an important role because Certificate Revocation List (CRL) is the list of certificates revoked by the CA that were previously issued and set to expire.

Without CRL, PKI would never able to identify whether a certificate has been revoked before it’s expiration. The Certificate Revocation List (CRL) is checked by RADIUS on the server during this process. A RADIUS server only rejects a connection request if the device’s certificate serial number is already present in the CRL. This feature is beneficial if a device gets stolen, an employee’s permissions change, or something like that.

Certificate Revocation

Certificate Revocation is the last stage of a certificate lifecycle. This phase comes when a certificate expires or when CA revokes the certificate just before the expiry date. CA automatically adds a certificate to the CRL when it is revoked and thus instructing RADIUS to no longer authenticate it.

CRLs can be exhaustive, and the client which conducts these checks must parse through the whole list to find the requested site’s certificate, whether it is present or not. Another method to check revocation status of a digital certificate is Online Certificate Status Protocol (OCSP). It is simple and faster as compared to CRLs because the certificate check is done by CA rather than PKI in CRLs.

In this method, instead of downloading and parsing the entire CRL, the client can send the selected certificate to the CA, upon which the CA returns the status of the certificate like – “Good,” “Revoked,” “Unknown,” or so on. It involves far less overhead than the CRL method.

Certificate Renewal

If a certificate policy allows a certificate that has already reached its expiration date, it is renewed either automatically or by the user’s intervention. When a renewal process is to be started, the user needs to choose whether to generate new public and private keys or reuse the existing ones. Generating new key pairs provides a new level of security which helps mitigating the risk of compromise of key over the time.

Renewal process also includes generating a Certificate Signing Request (CSR). This CSR will include the necessary information for the CA to issue the renewed certificate, such as the public key, organization details and domain name. The CSR is then submitted to the CA which basically validates the request based on its policies and procedures. After CA completes the validation, it issues the renewed certificate.

Certificate Destruction

When a certificate has no more uses, that certificate and all its backup copies or archives need to be destroyed along with the associated private key. This helps in ensuring that the certificate is not compromised and used. This is typically done through secure digital shredding methods or physical destruction of storage devices, ensuring that no remnants of the certificate can be recovered.

The process should be meticulously documented and integrated with Key Management Systems (KMS) to maintain audit logs, ensuring compliance with organizational policies and regulatory requirements, thereby safeguarding against any unauthorized use of the certificate.

Certificate Auditing

Certificate auditing tracks the creation, expiration, and revocation of certificates. In certain instances, it is also used for tracking the successful use of a certificate. This comprehensive process includes maintaining detailed records of certificate issuance, such as the issuer, date of issuance, and the purpose of the certificate, which helps in tracking its lifecycle and ensuring accountability.

Monitoring expiration dates is crucial for enabling timely renewals, thereby preventing disruptions in service and maintaining continuous security coverage. Logging revocations is essential to prevent the use of compromised or obsolete certificates; this involves updating Certificate Revocation Lists (CRLs) and ensuring that systems recognize and reject revoked certificates to mitigate security risks.

Certificate Lifecycle Management for SSL/TLS Certificate

Certificate Lifecycle Management is one of the essential things in proper PKI management. Apple has decided unilaterally to only trust 398 days of valid SSL and TLS certificates, despite the industry consensus to reject the proposal. This regulation came into effect starting 1st September 2020 and impacted only newly issued certificates as existing certificates were grandfathered in. The average validity period for all the certificates, including SSL/TLS, decreased from 2 to 5 years. This industry trend of shorter certificate lifecycles proved beneficial as it is more secure to replace certificates more frequently, whether necessary or not. This was still an improvement from the 90-day password replacement policies.

Conclusion

At the core of an effective certificate lifecycle management system lies a strict management program for an organization. Organizations without proper certificate lifecycle management are prone to face security and management issues, and certificates may get lost in the system, expire, and cause a loss in revenue. For a certificate lifecycle management to be effective, all the certificates it generates must be consolidated into a single machine identity management system.
