You can change the status of AppArmor by enabling or disabling it. Enabling AppArmor protects your system from potential program exploitation. Disabling AppArmor, even if your profiles have been set up, removes protection from your system. You can determine how and when you are notified when system security events occur.
NOTE: For event notification to work, you must set up a mail server on your system that can send outgoing mail using the single mail transfer protocol (SMTP), such as postfix or exim.

AppArmor can apply profiles in two different modes. In complain or learning mode, violations of AppArmor profile rules, such as the profiled program accessing files not permitted by the profile, are detected. The violations are permitted, but also logged. This mode is convenient for developing profiles and is used by the AppArmor tools for generating profiles. Loading a profile in enforce mode enforces the policy defined in the profile and reports policy violation attempts to syslogd.

This feature is useful for determining the status of your system during profile development. During the course of systemic profiling (see
