1.6.2.1 Ensure AppArmor is enabled in the bootloader configuration - security=apparmor

Information

Configure AppArmor to be enabled at boot time and verify that it has not been overwritten by the bootloader boot parameters.

Rationale:

AppArmor must be enabled at boot time in your bootloader configuration to ensure that the controls it provides are not overridden.

Solution

edit /etc/default/grub and add the appermor=1 and security=apparmor parameters to the GRUB_CMDLINE_LINUX= line

GRUB_CMDLINE_LINUX='apparmor=1 security=apparmor'

update the grub configuration

# update-grub

Notes:

This recommendation is designed around the grub bootloader, if LILO or another bootloader is in use in your environment enact equivalent settings.
