AppArmor Policy Violation Detected

Identifies events where the AppArmor security module blocked or restricted an operation due to a policy violation. AppArmor enforces mandatory access control policies that limit how processes interact with system resources such as files, network sockets, and capabilities. When a process attempts an action that is not permitted by the active profile, the kernel generates a policy violation event. While these events can occur during normal operation or misconfiguration, they may also indicate attempted privilege escalation, restricted file access, or malicious activity being prevented by the system's security policy.
