1.6.2.1 Ensure AppArmor is not disabled in bootloader configuration

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 /boot/grub/menu.lst and remove all instances of apparmor=0 on all kernel lines.

Additional Information:

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