What is SHA- 256?

SHA, which stands for Secure Hash Algorithm, is a family of cryptographic hash functions designed by the National Security Agency (NSA) and published by the National Institute of Standards and Technology (NIST) in the United States. It is part of the larger family of hash functions used for various cryptographic applications.

Introduction of SHA-256

SHA-256, part of the SHA-2 algorithm family, is a Secure Hash Algorithm introduced collaboratively by the NSA and NIST in 2001. It emerged as a robust successor to the SHA-1 family, which faced increasing vulnerabilities to brute force attacks.

The “256” in SHA-256 signifies its fixed hash digest size, always producing a 256-bit value, regardless of the input plaintext or cleartext size. This characteristic ensures consistent and strong cryptographic hashing.

Within the broader SHA family, SHA-256 shares similarities with its counterparts. Its development marked a crucial milestone in cryptography, addressing security concerns prevalent in earlier algorithms like SHA-1.

How does it work?

We want to hash the message “Hello, SHA-256!” using SHA-256. Here are the steps:

Message Padding

The ASCII representation of “Hello, SHA-256!” is converted to binary: 01001000 01100101 01101100 01101100 01101111 00101100 00100000 01010011 01001000 01000001 00101101 00110010 00110011 00110110 00100001. Append a ‘1’ bit to the end of the message: 01001000 01100101 01101100 01101100 01101111 00101100 00100000 01010011 01001000 01000001 00101101 00110010 00110011 00110110 00100001 1.

(Note: The actual padding involves more than adding a ‘1’ bit, including appending the original message length, but this is simplified for illustration.)
Initialization

The initial hash values (eight 32-bit words) are set. These values are defined in the SHA-256 specification.
Processing in Blocks

Divide the padded message into 512-bit blocks. For each block, perform a series of bitwise operations, modular additions, and logical functions using the current hash value and the block.
Compression Function

A compression function is applied to each block, creating a new hash value. This function involves mixing the bits of the current hash value and the message block.
Iteration

Repeat the compression function for each block, using the output of each iteration as input for the next.
Output

The final hash value after processing all blocks becomes the SHA-256 hash of the original message.

In reality, this process involves many complex bitwise operations and transformations. The resulting SHA-256 hash for our simplified example would be a 256-bit hexadecimal string.

Where can it be implemented?

SHA-256, a cryptographic hash function, finds applications in various areas where data integrity and security are crucial. Here are some common implementations:

Digital Signatures

SHA-256 is often used with public-key cryptography to create digital signatures. It allows for the verification of the integrity and authenticity of digital messages or documents.
Blockchain Technology

SHA-256 plays a fundamental role in blockchain technology. It generates the hash values of blocks in a blockchain, ensuring the immutability and integrity of the entire chain.
Password Hashing

In secure password storage, systems store the SHA-256 hash of the password instead of storing the actual password. This enhances security by preventing exposure to plain-text passwords in case of a data breach.
Secure Communication

Hash functions like SHA-256 are used in secure communication protocols to ensure the integrity of transmitted data. For example, in TLS/SSL protocols, hash functions are used with digital signatures to provide secure communication over the Internet.
Certificate Authorities (CAs)

SHA-256 is commonly used to create and verify digital certificates issued by Certificate Authorities. It helps ensure the authenticity and integrity of these certificates.
File Integrity Checking

SHA-256 generates checksums or hash values for files. Users can then verify the integrity of files by comparing the computed and original hash.

Advantages and Disadvantages

Advantages	Disadvantages
SHA-256 ensures data remains unchanged during transmission.	Once data is hashed, it cannot be reversed or decrypted to retrieve the original data.
SHA-256 provides a high level of security, making it practically impossible to derive the original data from its hash value.	Although rare, there is a theoretical possibility of hash collisions, where two different inputs produce the same hash value.
SHA-256 is a cornerstone of blockchain technology, ensuring the integrity and immutability of blocks.	Being deterministic, the same input will always produce the same hash, which may lead to potential vulnerabilities in some scenarios.
SHA-256 computations are relatively fast on modern hardware.	While SHA-256 has a high resistance to collision attacks, its resistance to pre-image attacks is theoretically less than collision resistance.

CI/CD and its Integration with Code Signing

Automated Certificate Lifecycle Solution

CI/CD pipelines are an integral part of modern workflows and the tools that support them further expand their latent capabilities. Team effort is essential in modern workflows where deadlines are not only urgent but regular as well. Every second counts when a customer is waiting on the other end.

Having a big organization that requires multiple steps in the process of developing code can become daunting when faced with manually handling each step of the process. That’s why tools like CI/CD pipelines, such as Jenkins, have become so commonplace now in developer workspaces. The best place to start the discussion on CI/CD therefore is what the tools allow you to accomplish. 

What is a CI/CD Pipeline?

The idea behind a pipeline is that it is a series of processes that drive software development through the steps of building, testing, and deploying code. This is also referred to as CI/CD. CI/CD is a model for a shared, usually locally hosted, build environment. The various platforms bundle implementations of CI/CD with communication and build tools that allow software to go live sooner by streamlining the build and release process.

Historically code is developed by separate teams and tested in personal environments, integration takes time, and feedback on broken code takes longer. This leads to lengthy build cycles and decreases in efficiency. It’s common practice to test a piece of code with some amount of test cases designed before development.

If the final code meets these standards, it should integrate into existing code easily. But as developers, we all know this is far from the only possible outcome even with meticulously designed test cases. As you can tell, CI/CD is the basis of DevOps in general. It focuses on continuous integration, delivery, and deployment.

The integration steps involve building the code itself, running test cases, and merging that code together. The delivery phase automatically releases the code to the specified repository, and the deployment phase, as it suggests, automatically deploys the code to the production environment.

Even though there are many steps through the CI/CD pipeline, one of the most important steps in this process is the ability to test code. CI/CD presents a way to execute test cases at scale, where changes to code can be tested in a single streamlined and automated action.

Code is pushed, received by the pipeline, tested and if all cases pass, the build can be set to go live. It’s amazing what this can do for your organization’s agility. Fixing a bug on a dime is quite possibly the future of development. Except we are missing an important step here. No customer or organization should be running unsigned code. This is where code-signing comes into play.

What is Code-Signing and Why is it Important?

Code-signing is the process of generating a digital signature and attaching it to code, so that an end-user can trust that the code distributed to them is safe to use. The basics of code-signing are as follows:

A developer will decide that they wish to sign their code. This will occur with most developers now, as providing an end-user with unsigned code is unsafe and insecure.
Once a developer decides to sign their code, they must then generate a public-private key pair, and a Certificate Signing Request (CSR). The public-private key pair identifies the developer as themselves and is necessary to create the CSR. The CSR is given to a Certificate Authority, along with the key pair, and is necessary to generate a digital signature for the code.
The public key of the public-private key pair is then sent to the Certificate Authority, or CA, and a code signing certificate is requested.
The CA then verifies the identity of the publisher, authenticates the publisher’s certificate request, and then bundles the identity of the publisher with the public key.
The CA then signs the bundle, thus creating a digital code signing certificate. This certificate allows the developer to generate a digital signature for the code in question, identifying that the code was developed by the software publisher.
Finally, the signing certificate is sent to the software publisher and they can now generate their digital signature and attach it to their code.

The modern release process demands codesigning, a step that depending on your organization’s current process, could greatly reduce the speed and efficiency conferred by CI/CD. Code-signing proves the identity of the developer of the code, as well as ensures the integrity of the code.

When code-signing occurs, any further modifications will invalidate the signature, providing assurance that signed code is free of tampering. This is the central benefit of codesigning that makes it so necessary in the modern world. Regardless of your industry, your products will be unusable in environments from school networks to banks if you do not implement code-signing.

There is also the benefit of mitigating risks for reputational damage. By only distributing signed code, your organization can ensure that users are used to seeing a signature before installing your software. This leaves them less vulnerable to attackers impersonating your organization. 

Integrating Code-Signing with CI/CD pipeline

Code-Signing used to be a separate process while developing. This step was often performed manually leaving room for errors. Integration with a CI/CD pipeline for performing Code-Signing can offer several benefits. The Code-Signing process can easily be automated with this integration which further eliminates the manual work needed to get artifacts signed before deploying it.

There are several CI/CD tools such as Jenkins, Azure DevOps, GitHub Actions, GitLab and others which allow easy integration with Code-Signing tools. Overall, this results in the Code-Signing process being automatic in the present development and deployment workflow.

When we automate our workflows to sign our artifacts we can see many advantages. Automation like this, with the help of a CI/CD pipeline, ensures consistency. All the code released will have the same signing process which ensures reliable deployments. It also saves the time of the deployment team by eliminating the manual signing process.

Overall, this reduces the risk of human error which could occur during manual signing. This integration of CI/CD pipeline with Code-Signing is a win-win situation as it strengthens your security posture by ensuring integrity as well as streamlines the developmental process which leads to faster and more efficient software delivery.

Benefits of Code-Signing in CI/CD

Enhanced Security
When you sign code in the CI/CD pipeline, you always ensure that only the allowed and verified code is deployed in production environments. This method lowers the chances of inserting vulnerabilities. Whenever there is an attempt at tampering with it, the signature will be invalidated, signaling that there may be potential security threats. By doing so, any individual who might want to put malware into the pipeline and conduct supply chain attacks is kept away.
Automated Releases
Once the Code-Signing process within the CI/CD pipeline has been automated, a typical signing process is set up. This automation always takes place no matter the developer and in which environment of development builds occur.

As a result of this step, developers don’t have to sign code manually anymore, thus freeing their time up for other tasks; it also reduces the number of mistakes while signing because everything goes without human interruption. Human errors can be avoided completely since everything goes on without any human intervention. If we include automated signing as one of our pipelines for CI/CD, we will have quicker releases.
Better Development Practices
When CI/CD tools are linked with Code-Signing, signing errors are noted with a failure notification. Such notification allows the developer to notice an error and rectify it early in the development process. The logs on build and deployment activities are always more detailed in CI/CD pipelines. In this case, they keep track of Code-Signing and offer clarity that is needed when adhering to security regulations.

CI/CD and DevSecOps

DevSecOps stands for development, security, and operations. It is a way of moving ahead with development where everyone involved in building software collaborates to ensure the software is secure from the start. DevSecOps relies on automated pipelines for testing, deployment, and monitoring throughout the software development cycle.

Securely signed artifacts flow effortlessly through these automated pipelines of CI/CD, maintaining their integrity and security posture at every stage. The signing process can be automated within the build pipeline, seamlessly adding security to the development workflow. DevSecOps in simple words is DevOps CI/CD but in a secure way. This demonstrates that security is a primary concern that impacts all decisions and steps taken along the development lifecycle.

Integrating a CI/CD Pipeline with an HSM

So, we need code signing, but an automated build system with direct access to keys is a recipe for disaster. Leaks and compromises happen, it’s essential to properly store and protect your codesigning keys in a Hardware Security Module, or HSM. The consequences of not securing codesigning keys with an HSM have already been seen in the last year, with organizations losing access to their codesigning keys that service firmware.

Because they service firmware, these keys cannot be cycled or replaced, and the consequences will haunt the affected companies for potentially years. HSMs are tools not just for code signing, but also for securing Public Key Infrastructure’s and database encryption keys as well. It must be said that HSMs are an essential tool for almost all organizations storing data, encryption keys, or developing code.

Now when we talk about HSMs, some with mild experience may think managing an HSM can be a difficult process. Optimal security means regular updates to firmware and software, regular audits, and properly managing access to keys. In addition, there is the work of actually integrating the HSM into your existing pipeline.

Custom work from a certified HSM engineer is expensive and time-consuming, and if something breaks, having to contact someone outside your company can prove slow and impractical. To solve the issues and complexities presented thus far, Encryption Consulting has developed a competitively priced solution in Code Sign Secure and its integration with any HSM your organization may desire.

Leveraging the capabilities and security of HSMs such as the Thales, Entrust, or Utimaco HSMs, Code Sign Secure will easily integrate into your existing pipelines, streamlining the codesigning process. 

Conclusion

Depending on your current company size, you may already have a data center, likewise, you may not want to invest in a data center as it’s simply impractical for the size of your organization. In either case Code Sign Secure can meet your needs with its on-premises or system-as-a-service solutions.

System-as-a-service offerings save you the headache of owning and maintaining an HSM, however, if your organization already owns an HSM or is concurrently implementing PKI or another HSM-dependent service, the same HSM can support Code Sign Secure. For this reason, the best choice for your organization depends on your security roadmap.

Luckily Encryption Consulting can work with your organization to help plan a path forward, identifying current shortcomings in the security space as well as needs for your organization. We provide audit and consulting services and will employ our team of industry experts to identify the solution ideal for you. 

Navigating the Perils: Risks and Challenges with Compromised Code Signing Certificates

Code signing certificates play a major role in proving the authenticity and integrity of software applications within and outside an organization. It provides a crucial line of defense and assures users and developers about the application they can trust. Once an application is signed, no malicious party can inject malware or other offensive measures as code signing provides integrity to the original application.

However, disasters cannot be nullified. Certificates can be compromised and stolen, and some bad actor can take control of it. The consequences of such a compromise can be diverse, which can present a host of risks and challenges that an organization and the users of the application will face.

Understanding Code Signing Certificates

Before delving into the risks associated with compromised code signing certificates, it’s important to grasp the role of code signing certificates in data protection. Code signing certificates serve as digital signatures, verifying the source and integrity of software code. When developers sign their code with these certificates, users can trust that the software hasn’t been tampered with or altered by malicious entities.

The Risks of Compromised Certificates

Malware Distribution

Perhaps the most immediate risk of compromised code signing certificates is the potential for malware distribution. Attackers who gain access to legitimate certificates can sign malicious codes, effectively bypassing security measures and gaining users’ trust. This can lead to the widespread dissemination of malware, causing significant damage to individuals and organizations.
Phishing Attacks

Compromised code signing certificates can also facilitate sophisticated phishing attacks. By signing phishing emails or fraudulent websites with legitimate certificates, attackers can deceive users into believing that the content is trustworthy. This increases the likelihood of successful phishing attempts, as unsuspecting individuals may be more inclined to divulge sensitive information.
Exploitation of Trusted Relationships

Code signing certificates are built on trust. When these certificates are compromised, it undermines the trust relationship between software developers and users. Malicious actors can exploit this breach of trust to execute various attacks, leveraging the credibility associated with legitimate certificates to infiltrate systems and networks undetected.
Damage to Reputation

For organizations whose code signing certificates are compromised, the damage extends beyond immediate security concerns. A breach of this nature can tarnish their reputation, eroding trust among customers, partners, and stakeholders. Rebuilding trust and restoring confidence in their products and services can be a long and arduous process.

Challenges in Mitigating Compromised Certificates

Addressing the risks posed by compromised code signing certificates presents several challenges:

Detection and Remediation

Identifying compromised certificates amidst the vast sea of digital signatures can be like finding a needle in a haystack. Organizations must invest in robust security measures and monitoring tools capable of detecting unauthorized use of certificates promptly.
Certificate Lifecycle Management

Managing the lifecycle of code signing certificates is essential for preventing compromises. This includes proper issuance, renewal, and revocation procedures. However, maintaining oversight of numerous certificates across diverse environments can be complex and resource intensive.
Regulatory Compliance

Compliance with regulatory frameworks such as the Payment Card Industry Data Security Standard (PCI DSS) or the General Data Protection Regulation (GDPR) adds another layer of complexity to certificate management. Organizations must ensure that their practices align with relevant regulations to avoid penalties and legal repercussions.

Recommendations and Best Practices

Implement Multi-factor Authentication (MFA)

Enforce multi-factor authentication for accessing code signing certificate management systems. This adds an extra layer of security, making it harder for unauthorized individuals to gain access to sensitive resources.
Regularly Rotate Certificates

Implement a regular rotation policy for code signing certificates. By regularly replacing certificates with new ones, organizations can limit the window of opportunity for attackers to exploit compromised certificates.
Monitor Certificate Usage

Utilize monitoring tools to track the usage of code signing certificates across your organization’s infrastructure. This includes monitoring certificate issuance, revocation, and any unusual or unauthorized activity associated with certificate usage.
Encrypt Certificate Storage

Store code signing certificates in encrypted repositories or hardware security modules (HSMs) to protect them from unauthorized access. Encryption adds an additional layer of security, ensuring that even if certificates are compromised, they remain inaccessible to attackers.
Establish Certificate Revocation Policies

Define clear procedures for revoking compromised certificates promptly. Ensure that all stakeholders are aware of these policies and understand their role in initiating certificate revocation when necessary.
Segment Certificate Access

Limit access to code signing certificates based on the principle of least privilege. Only grant access to individuals who require it for their specific roles and responsibilities, and regularly review and update access permissions as needed.
Regular Security Audits and Penetration Testing

Conduct regular security audits and penetration testing to identify vulnerabilities in your code signing certificate management systems and infrastructure. Address any identified weaknesses promptly to mitigate potential risks.
Stay Informed About Threats and Vulnerabilities

Stay abreast of emerging threats and vulnerabilities related to code signing certificates and update security practices accordingly. Engage with industry forums, attend security conferences, and leverage threat intelligence sources to stay informed about the latest trends and developments.

Code Signing Processes: A Guide to Navigating Your Code Signing Progress Journey

In the constantly evolving digital technology world, the significance of code signing has become more apparent. Code signing is a security practice in which software is digitally signed in order to ensure its authenticity and integrity. This method is integral in developing trust, avoiding manipulation, and securing individuals and organizations from unforeseen attacks.

But how secure the process you follow to perform this operation is in question. Are your private keys stored securely in hardware crypto modules such as HSMs, and are those HSMs at least FIPS 140-2 Level 2 or Common Criteria EAL 4+, or are those keys just stored in local machines?

The significance of securely keeping private keys used in code signing cannot be emphasized because these keys form the foundation of the security process. Private keys are sensitive information that should only be accessed by authorized persons.

An attacker can sign and circulate malicious software as genuine code if private keys are compromised. Private keys used in code signing must be securely stored to ensure software trust, integrity, and security. Organizations must establish strong security measures like encryption, access limitations, and frequent audits to protect these keys from unauthorized access and potential compromise.

Maturity Model for Code Signing

How secure or established your code signing process is can be evaluated with the help of a maturity model. Organizations may evaluate, comprehend, and enhance their practices over time using a maturity model, which provides an organized framework. A maturity model’s value in the context of code signing comes from its capacity to direct companies toward a safer and more effective method of developing software.

Maturity models offer a systematic strategy for analyzing the present condition of an organization. Organizations can determine their existing code signing procedures by establishing several maturity levels. A maturity model’s levels correspond to successive phases of development. This gradual approach enables enterprises to concentrate on specific elements of code signing, tackling issues one step at a time. Instead of seeking drastic changes all at once, it offers a feasible and realistic growth route.

One essential element of software security is code signing. A maturity model places a strong emphasis on the creation of policies, ongoing monitoring, and secure key management. By minimizing the possibility of key compromise and unauthorized access, as well as guaranteeing the integrity of signed code, moving up the maturity stages improves security overall.

Code signing maturity models are more than just checklists; they are strategic tools that enable businesses to develop methodically, improve security procedures, and adjust to the always-shifting fields of cybersecurity and software development. The phases listed below can be used to assess the maturity of your present code signing procedure.

Level 1: Initial

Ad hoc Code Signing

There are no established procedures or standards; code signing is carried out on an as-needed basis. Code signed by several teams or individuals may be inconsistent or not signed at all, resulting in software integrity problems and security flaws.
Limited Awareness

Team members may not completely understand the significance of code signing or its wider security implications while having a fundamental understanding of the concept. They may be unaware of safe procedures or the consequences of using the wrong code signature.

Level 2: Managed

Defined Process

During the managed stage, code signing practices are being actively implemented by businesses. Such practices entail creating workflows, recording procedures, and specifying roles and duties for code-signing tasks. Teams may decrease the possibility of mistakes or oversights and guarantee consistency by using well-defined procedures.
Centralized Key Management

Organizations centralize handling of the private keys needed for code signing in order to improve security. By improving control and monitoring over key usage, centralized key management lowers the possibility of misuse or unauthorized access to private keys.

Level 3: Standardized

Consistent Implementation

Code signing procedures are uniformly used in all software releases at the standardized level. All software updates and releases are signed according to the specified procedures and guidelines. This guarantees that, before deployment, all code is subjected to an equal level of security evaluation.
Policy Development

Organizations implement continuous monitoring for code signing activities to detect anomalies or deviations from established norms. These guidelines ensure compliance with security goals and legal requirements by outlining code signing criteria, protocols, and best practices.

Level 4: Optimizing

Automated Workflows

Windows Hello for Business Deployment Models

Windows Hello for Business offers various deployment options that organizations can choose from. Though it may seem complex, most organizations will realize that they have already implemented most of the infrastructure necessary for the deployment.

There are three deployment models available: cloud-only, hybrid, and on-premises.

Cloud-Only Deployment Model

The exclusive reliance on cloud identities characterizes the cloud-only deployment model, tailored for organizations without on-premises resources. These entities connect their devices to the cloud, depending entirely on resources like SharePoint and OneDrive.

Pros

Streamlined Management

Cloud-only deployments simplify management by utilizing cloud-based services for configuration, monitoring, and updates, alleviating the workload on IT administrators.
Scalability

Cloud solutions offer enhanced scalability, enabling organizations to effortlessly accommodate increasing numbers of users or devices without substantial infrastructure investments.
Flexibility

Cloud-only deployments afford flexibility in terms of device location and user access, allowing authentication from any location with an internet connection—particularly advantageous in remote or distributed work environments.

Cons

Dependency on Internet Connection

Cloud-only deployments heavily rely on internet connectivity, making users’ ability to authenticate vulnerable to disruptions in workflow during internet issues.
Security Concerns

Some organizations express apprehensions about relying solely on the cloud for sensitive authentication data, despite robust security measures employed by Microsoft.
Data Privacy and Compliance

Concerns about data privacy and compliance may arise, especially for organizations handling biometric data stored in the cloud.

On-Premises Deployment Model

Exclusively designed for enterprises utilizing on-premises Active Directory, the on-premises deployment model does not involve cloud identities or applications hosted in Microsoft Entra ID.

Pros

Local Control

On-premises deployments provide direct control over the entire Windows Hello for Business infrastructure, a crucial aspect for organizations with specific security and compliance requirements.
Data Residency

Some organizations prefer keeping authentication data within their own data centers for regulatory reasons, ensuring control over data residency.
Reduced Dependency on Internet Connectivity

On-premises deployments mitigate reliance on constant Internet connectivity, allowing authentication processes to continue even during temporary disruptions in Internet access.

Cons

Limited Remote Access

Challenges may arise for remote access scenarios, with users outside the organization’s network experiencing limitations, necessitating additional solutions for remote workforce scenarios.
Complexity of Maintenance

Managing on-premises infrastructure demands dedicated resources for maintenance, updates, and troubleshooting, introducing complexity and requiring skilled IT staff.
Scalability Challenges

Scaling on-premises infrastructure for a growing user base may involve significant upfront investments and planning compared to cloud-based solutions.

Hybrid Deployment Model

Tailored for organizations federated with Microsoft Entra ID, the hybrid deployment model involves synchronized identities and applications hosted in Microsoft Entra ID. It aims to provide a unified single sign-on user experience for both on-premises and Microsoft Entra resources.

Pros

Flexibility

Hybrid deployments strike a balance between on-premises control and cloud flexibility, suitable for organizations integrating modern authentication methods with existing on-premises infrastructure.
Local Control

On-premises components grant local control over specific authentication aspects, such as device registration, certificate authorities, and key storage—crucial for organizations with specific security and compliance requirements.
Compliance Options

Organizations can address compliance and data residency concerns by carefully managing where certain authentication data is stored and processed, whether on-premises or in the cloud.

Cons

Complexity of Configuration

Setting up and configuring a hybrid deployment can be more intricate than opting for a purely on-premises or cloud-based solution, requiring meticulous planning for optimal functionality and seamless integration.
Dependency on Internet Connectivity

Similar to cloud-only deployments, a Windows Hello hybrid model relies on Internet connectivity for specific authentication processes, making the user experience susceptible to connectivity issues.
Management Overhead

Managing a hybrid deployment necessitates expertise in both on-premises and cloud technologies, adding to the complexity as IT administrators monitor and maintain components in both environments.

Trust Models

The trust model plays a pivotal role in determining the user authentication method for the on-premises Active Directory. Three trust models are supported in a hybrid environment: Key Trust, Certificate Trust, and Cloud Kerberos Trust. On-premises deployment models support Key Trust and Certificate Trust only.

Key Trust Model

The key trust type eliminates the need to issue authentication certificates to end users. Users authenticate using a hardware-bound key generated during the built-in provisioning experience.
Certificate Trust Model

The certificate trust type involves issuing authentication certificates to end users. Users request a certificate using a hardware-bound key created during the built-in provisioning experience for authentication.
Cloud Kerberos Trust Model

The Windows Hello for Business cloud Kerberos trust employs Microsoft Entra Kerberos, streamlining deployment in comparison to the key trust model.

Comparison between the trust models

The table below highlights the key differences between the Cloud Kerberos Trust Model, Certificate Trust Model and the Key Trust Model.

Criteria	Cloud Kerberos Trust Model	Certificate Trust Model	Key Trust Model
User Authentication	Using Microsoft Entra Kerberos, users request a Ticket Granting Ticket from Microsoft Entra ID for authentication.	Users require a certificate, requested using a device-bound key, for authentication.	Users use a device-bound key for authentication.
Deployment model	Supported by Hybrid deployment model only	Supported by Hybrid and on-premises deployment model	Supported by Hybrid and on-premises deployment model
PKI requirement	PKI is not required	PKI is required	PKI is required

Comparison between the deployment models

This table provides a comparison of key features across the three Windows Hello deployment models. Organizations should carefully evaluate their requirements to determine the most suitable deployment approach.

Feature	On-Premises Deployment	Cloud-Only Deployment	Hybrid Deployment
Control and Management	Local control over infrastructure and data.	Managed through cloud-based services.	Balance between on-premises control and cloud flexibility.
