asr wdac

The asr wdac tag covers discussions about Attack Surface Reduction (ASR) rules and Windows Defender Application Control (WDAC) as security controls in Microsoft 365. A recent thread highlights Microsoft's retirement of Microsoft Defender Application Guard (MDAG) for Office, with documents shifting to Protected View. Administrators are advised to rely on ASR rules and WDAC to maintain security after MDAG removal, which begins in early 2026 and completes by December 2027. The tag focuses on enterprise IT security, Windows Defender features, and Microsoft 365 policy changes.
