AppArmor

====================================================================================

AppArmor is a high-level security system, primarily designed for use on Debian-based systems.

AppArmor itself is installed on most new Debian systems, however, to customise the configuration you'll need to ensure that the apparmor-utils package installed.

The primary difference between AppArmor and SELinux is that AppArmor bases its security policies off inode location, whereas SELinux uses a contextual system.
