Windows Server is getting new network safety capabilities with DNS over HTTPS

Microsoft has introduced DNS over HTTPS (DoH) on Windows Server 2025, enhancing network security by encrypting DNS traffic for client-to-server communications. This feature, previously available only in Windows client editions, is now part of Microsoft's Zero Trust architecture. DoH routes DNS traffic through HTTPS secured with TLS certificates, preventing eavesdropping and safeguarding DNS data from tampering. It adheres to the IETF DNS over HTTPS standard (RFC 8484) and can integrate with existing infrastructure, allowing organizations to maintain unencrypted DNS traffic if needed. DoH is available for Windows Server 2025 systems updated to the latest Patch Tuesday release, and Microsoft has provided guidance on enabling this feature. However, DNS traffic exchanged between two DNS servers will not be encrypted by DoH.

Windows Server 2025 Adds DNS Over HTTPS for Secure DNS Traffic

Microsoft has rolled out support for DNS over HTTPS (DoH) in Windows DNS Server as part of the Windows Server 2025 update. This feature enhances the security of DNS communications through encryption and server authentication, allowing encrypted client-to-resolver traffic in on-premises DNS environments. DoH encrypts DNS queries and responses using HTTPS, protecting sensitive information from interception or alteration. It also uses digital certificates for DNS server authentication to reduce spoofing and impersonation risks. The feature is compatible with existing Windows DNS Server configurations and supports both encrypted and traditional DNS. DoH support is available on Windows Server 2025 with the June 9, 2026 update or newer. Administrators must configure a trusted TLS certificate and enable DoH in the DNS Server service to deploy this feature. Microsoft plans to extend encryption capabilities to include communication between the Windows DNS Server and upstream DNS resolvers in the future.

ADCS Now Generates Post-Quantum Certificates For Windows

Active Directory Certificate Services (ADCS) now supports the generation of post-quantum certificates, enhancing quantum-safe cryptography within Windows' secure connection protocols. Microsoft has integrated PQ TLS hybrid key exchange into the Windows Transport Layer Security (TLS) stack, providing protection against "Harvest Now, Decrypt Later" attacks. The PQ TLS hybrid key exchange combines traditional cryptographic methods with the NIST ML-KEM algorithm, offering three hybrid combinations: X25519MLKEM768, SecP256r1MLKEM768, and SecP384r1_MLKEM1024. This feature is available in preview via the Windows Insider Program and will be rolled out to Windows 11 and Windows Server. Additionally, Windows cryptography APIs now support composite ML-KEM and ML-DSA algorithms, which are NIST-approved standards for key exchange and digital signatures, enhancing security by requiring multiple components to be compromised. Microsoft emphasizes the importance of establishing new Certification Authorities (CAs) for implementing post-quantum certificate issuance, as existing CAs cannot be upgraded. The introduction of ML-DSA support within ADCS allows organizations to counter HNDL risks associated with long-lived data. Organizations are encouraged to inventory their use of public-key cryptography, prioritize systems protecting sensitive data, and test hybrid and composite approaches in non-production environments to facilitate a smooth transition to quantum-safe cryptography.
