PKI Reading Time: 10 minutes

Windows 2012 R2 EOS – Is your PKI running on Windows 2012 R2? Are you prepared to Migrate?

In the world of information technology, change is constant. Technology evolves rapidly, so businesses must adapt to keep up with the latest advancements. One area that often requires attention is the management of digital certificates, which play a vital role in ensuring secure communications and data integrity. If your organization’s Microsoft Certificate Authority (CA) runs on Windows Server 2012 and 2012 R2, it’s time to start thinking about a migration strategy as soon as possible.

Microsoft will stop supporting windows server 2012 and 2012 R2 on 10th Oct 2023. Microsoft will discontinue offering bug fixing, technical support, or any new problem that can affect the reliability or usability of servers.

How Serious Is the Risk?

Using Windows Server 2012 and 2012 R2 comes with several risks due to the operating systems reaching the end of their supported lifecycle. These risks can have serious implications for organizations, as this risk leads to being subject to compliance issues and cyber attacks. The environment using unsupported servers will be the prime target for the bad guys. Without an upgrade strategy, the organization’s IT parties and management will be responsible for the jeopardy posed by unsupported servers.

Here are some of the key risks associated with using Windows 2012 and 2012 R2:

  • Security vulnerabilities

    As operating systems age, security vulnerabilities are discovered, and cybercriminals actively exploit them. Over time, the risk of security breaches and unauthorized access to your systems increases significantly. Without regular security updates and patches from Microsoft, any newly discovered vulnerabilities will remain unaddressed, exposing your system to potential attacks.

  • Lack of support

    When an operating system reaches its end of support, Microsoft no longer provides technical support or assistance for issues related to that version. This lack of support means that if you encounter any problems or face challenges with your Windows 2012 or 2012 R2 servers; you won’t be able to rely on Microsoft for help. This can lead to prolonged downtime, increased costs, and difficulty resolving critical issues.

  • Compliance violations

    Many industry regulations and standards, such as PCI DSS, HIPAA, and GDPR, require organizations to use supported software and regularly apply security updates. By running unsupported operating systems, you risk non-compliance with these regulations, which can result in penalties, legal liabilities, and damage to your organization’s reputation.

  • Limited feature enhancements

    With the end of support, there will be no new feature updates or enhancements for Windows 2012 and 2012 R2. This means you won’t benefit from the latest functionalities, improvements, or performance optimizations available in newer operating systems. Staying on outdated platforms can hinder your ability to leverage modern technologies and advancements that can drive efficiency and productivity.

  • Incompatibility with new software and hardware

    As software and hardware vendors release updates and new products, they increasingly focus on compatibility with the latest operating systems. Over time, you may encounter compatibility issues when installing or running newer software or hardware on Windows 2012 or 2012 R2. This can limit your ability to adopt new technologies and take advantage of the latest features and capabilities. For Example: Integration of Windows Hello.

The seriousness of these risks should not be underestimated. Running an unsupported operating system puts your organization’s security, stability, and compliance at significant risk. As time progresses, the risks associated with using Windows 2012 and 2012 R2 will only increase as cyber threats evolve and unsupported systems become more susceptible to attacks.

Planning and executing a migration to a supported operating system version on time is essential to mitigate these risks. This ensures that you can continue to receive security updates, access technical support, and maintain compliance with industry standards, while also taking advantage of the latest features and improvements offered by modern operating systems.

Is this the right time to assess your PKI needs?

Since we are at a forced decision point, it may be the right time for you to assess the current PKI environment and strategies to enhance your overall PKI infrastructure. Asking the right questions will help you understand your PKI environment’s as-it-is and as-to-be state

To understand your organization’s approach to PKI (Public Key Infrastructure), it’s essential to ask the right questions. These questions will help you assess your current PKI architecture and make informed decisions about its future. Consider the following inquiries:

  1. Is it advisable to retain your existing PKI architecture, or would it be more beneficial to migrate?
  2. Have there been any changes in business use cases since the initial deployment of your PKI?
  3. Does your Microsoft PKI adequately support the evolving demands of PKI use cases?
  4. Are you familiar with your PKI architecture’s specific components and state, including its infrastructure, certificates, and dependencies
  5. Should you explore the adoption of cloud-based PKI or PKI-as-a-Service solutions?
  6. Have you conducted thorough testing of your migration plan?
  7. Have you developed a contingency plan in the event of issues during the migration process?

By asking these pertinent questions, you’ll gain insights into your organization’s PKI landscape, identify areas for improvement, and make informed decisions regarding the future of your PKI architecture.

Steps to prepare for the migration:

To ensure your organization’s continued security and compliance, it’s crucial to migrate your Microsoft CA from Windows Server 2012 R2 to a supported platform. Here are some steps you can take to prepare for the migration:

  1. Assess your current environment

    Begin by evaluating your existing CA infrastructure. Understand the scale of your certificate operations, including the number of certificates issued and the dependencies on the current CA. Identify any custom configurations or integrations that may need to be considered during the migration.

  2. Select a target platform

    Determine which version of Windows Server you plan to migrate to. Windows Server 2019 or the latest version available during migration are recommended choices. Evaluate each version’s features, compatibility, and support lifecycle to make an informed decision.

  3. Plan the migration process

    Develop a detailed migration plan outlining the steps, potential risks, and timelines. Consider factors such as downtime requirements, certificate validity periods, and communication with stakeholders. To ensure a smooth transition, engage key stakeholders, including IT personnel, security teams, and application owners.

  4. Test the migration in a lab environment

    Before performing the actual migration, set up a test environment to simulate the migration process. This allows you to identify and address any potential issues or conflicts before migrating your production CA.

  5. Perform the migration

    Once you’ve completed thorough testing, execute the migration plan in your production environment. Follow best practices provided by Microsoft or seek assistance from qualified professionals to ensure a successful migration.

  6. Validate and monitor

    After the migration, validate the functionality of your new CA infrastructure. Test certificate issuance, revocation, and renewal processes to ensure everything is functioning.
