ℹ️ Check
Verify NixOS is configured to use AppArmor with the following command:
$ sudo systemctl status apparmor.service
apparmor.service - Load AppArmor policies
Loaded: loaded (/etc/systemd/system/apparmor.service; enabled; present: enabled)
Active: active (running) since Sat 2022-06-04 02:51:43 UTC; 13min ago
If the "apparmor.service" is not enabled and active, this is a finding.
✔️ Fix
Configure NixOS to use AppArmor.
Add the following Nix code to the NixOS Configuration, usually located in /etc/nixos/configuration.nix or /etc/nixos/flake.nix:
security.apparmor.enable = true;
Rebuild and switch to the new NixOS configuration:
$ sudo nixos-rebuild switch
A reboot is required for the changes to take effect.
