A Debian 7.0 (Wheezy) or newer GNU/Linux system is required.

Install software

Install AppArmor userspace tools and some contributed profiles:

$ sudo apt-get install apparmor apparmor-profiles apparmor-utils

Enable AppArmor

Enable the AppArmor LSM:

$ sudo perl -pi -e 's,GRUB_CMDLINE_LINUX="(.*)"$,GRUB_CMDLINE_LINUX="$1 apparmor=1 security=apparmor",' /etc/default/grub
$ sudo update-grub
$ sudo reboot

Inspect the current state

See what running executables are currently confined by an AppArmor profile:

$ ps auxZ | grep -v '^unconfined'

Enable / install more profiles

Find more profiles:

Once you've dropped the new profile into /etc/apparmor.d/, use apparmor_parser(8) to insert it into the kernel.

AppArmor audit logs can be found in /var/log/kern.log.
