Microsoft has introduced new features in Windows 11 (24H2) and Windows Server 2025 aimed at enhancing both security and functionality. Among these updates is the controversial Recall feature, which was announced as an opt-in after users raised significant privacy and security concerns. Recall allows users to take snapshots of their actions on their machines, requiring advanced Neural Processing Units (NPUs) for functionality. Although it’s designed to create a searchable archive of user activities, its use raises potential issues surrounding data accessibility and privacy.
Organizations should seriously consider blocking Recall if it conflicts with their privacy policies, especially concerning independent or temporary workers accessing sensitive information. Past iterations of Recall have faced criticism for lacking encryption and being inadequately protected from unauthorized access.
Another technological advance is the hotpatching feature, allowing updates to be deployed without necessitating a system reboot. This feature is limited to Windows 11 Enterprise and requires specific licensing. Not every update qualifies for hotpatching; Microsoft has provided a schedule indicating which updates require restarts and which do not. Companies should reassess their security policies to accommodate hotpatching, especially if their current practices mandate frequent reboots.
Furthermore, security teams must evaluate their configurations regarding Entra ID logins, which should be prioritized over consumer Microsoft account authentication. Microsoft has recommended turning off certain user features like Recall and Copilot proactively and establishing policies to manage their functionalities.
On the Server 2025 front, new recommendations include implementing stricter account lockout settings, limiting login attempts to just three, and introducing policies that allow for better management of Local Administrator passwords.
Additionally, Microsoft is pushing for the gradual phasing out of NTLM authentication, known for its vulnerabilities. Two new policies aim to either block NTLM or create exceptions for specific servers. Organizations are encouraged to start evaluating their use of legacy authentication methods, as the landscape of security threats continues to evolve.
In summary, as organizations transition to Windows 11 24H2 and Server 2025, it’s crucial to review and update security policies, authentication processes, and configurations to embrace new technologies while safeguarding sensitive information. Organizations must strike a delicate balance between utilizing innovative features and maintaining a secure environment.
