    Microsoft has announced the release of the June 2025 revision of its security baseline package for Windows Server 2025 (v2506), it is now available to download from the Microsoft Security Compliance Toolkit. After downloading it, you can test the recommended configurations in your environment and customize or implement them as you see fit.

     

    To deal with the evolving threat landscape, new Windows features, and community feedback, Microsoft is planning to revise the Windows Server baseline more frequently in the future. Windows Server security baselines are a collection of Microsoft-recommended configuration settings that help administrators establish secure and consistent Windows Server environments.

     

    This is the first security baseline update for Windows Server 2025 since January, a summary of the changes is presented in this table:

     

    Security Policy

    Change Summary

    Deny log on through Remote Desktop Services

    Allow remote logon for non-admin local accounts on MS and add “BUILTIN\Guests” to both DC and MS.

    WDigest Authentication

    Remove from the baseline

    Allow Windows Ink Workspace

    Remove from the baseline

    Audit Authorization Policy Change

    Set to “Success” in both DC and MS

    Include command line in process creation events

    Enable in both DC and MS

    Control whether exclusions are visible to local users

    Moved to Not Configured as it is overridden by the parent setting.

     

    Of these changes, the removal of WDigest Authentication and the addition of Include command line in process creation events are significant.

     

    Microsoft said it removed WDigest Authentication from the security baseline because it is no longer necessary for Windows Server 2025. The policy was originally enforced so that WDigest couldn’t store plaintext passwords in memory, which was a significant theft risk. Since the 24H2 update in Windows Server 2022, the policy has been deprecated, so there’s no need to enforce this setting.

     

    The update also adds Include command line in process creation events to improve the visibility of how processes are executed across the system. By capturing the command-line arguments, it makes it easier to detect and investigate malicious activity that may otherwise seem legitimate.

     

    If you want to learn more about the other changes in a bit more depth, refer to Microsoft’s announcement of this security baseline update.
