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.
Note:
This recommendation is designed around the grub bootloader, if LILO or another bootloader is in use in your environment enact equivalent settings.
Fix:
edit /etc/default/grub and add 'apparmor=1' and 'security=apparmor' parameters to the GRUB_CMDLINE_LINUX
Parameter:
[yes/no]
Technical Mechanism:
edit /etc/default/grub and add apparmor=1 and security=apparmor parameters to the GRUB_CMDLINE_LINUX
