mandatory access control

Mandatory access control (MAC) is a security model that restricts how subjects can access objects based on system-enforced policies rather than user discretion. On WindowsForum.com, discussions about MAC often reference AppArmor, a Linux mandatory access control framework that enforces task-centered policies. For example, a thread on CVE-2026-23406 highlights a kernel bug in AppArmor's match_char macro that could lead to incorrect policy handling and denial-of-service conditions. This illustrates how flaws in MAC implementations can have security implications even when the root cause appears minor. While Windows uses its own MAC mechanisms like Mandatory Integrity Control, the tag covers cross-platform topics where mandatory access control is relevant to system security and policy enforcement.
