Enforce Mode

The default package configuration installs all profiles in complain mode. This is a safety measure to ensure you are not going to break your system on initial installation. Once you have tested it, and it works fine, you can easily switch to enforce mode. The profiles that are not considered stable are kept in complain mode, they can be tracked in the dists/flags directory.

Danger

  • You must test in complain mode first and ensure your system works as expected.
  • You must regularly check AppArmor log with aa-log and report issues first.
  • When reporting an issue, you must ensure the affected profiles are in complain mode.

Configuration

Set the default mode of aa-install to enforce in /etc/apparmor/modes

cat <<-EOF | sudo tee /etc/apparmor/modes
default enforce
EOF

Installation

To apply the change, start aa-install manually:

sudo aa-install
