1.6.1.2 Ensure AppArmor is enabled in the bootloader configuration - security

Information

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

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

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 apparmor=1 and security=apparmor parameters to the GRUB_CMDLINE_LINUX= line

GRUB_CMDLINE_LINUX='apparmor=1 security=apparmor'

Run the following command to update the grub2 configuration:

# update-grub
