The <literal>security.apparmor</literal> module,
|
||||
for the <link xlink:href="https://gitlab.com/apparmor/apparmor/-/wikis/Documentation">AppArmor</link>
|
||||
Mandatory Access Control system,
|
||||
has been substantialy improved along with related tools,
|
||||
so that module maintainers can now more easily write AppArmor profiles for NixOS.
|
||||
The most notable change on the user-side is the new option <xref linkend="opt-security.apparmor.policies"/>,
|
||||
replacing the previous <literal>profiles</literal> option
|
||||
to provide a way to disable a profile
|
||||
and to select whether to confine in enforce mode (default)
|
||||
or in complain mode (see <literal>journalctl -b --grep apparmor</literal>).
|
||||
Before enabling this module, either directly
|
||||
or by importing <literal><nixpkgs/nixos/modules/profiles/hardened.nix></literal>,
|
||||
please be sure to read the documentation of <link linkend="opt-security.apparmor.enable">security.apparmor.enable</link>,
|
||||
and especially the part about <xref linkend="opt-security.apparmor.killUnconfinedConfinables"/>.

Also, beware that enabling this module will by default

This will happen when upgrading to a NixOS revision
|

introducing an AppArmor profile for the executable of a running process.
|

This is because enabling an AppArmor profile for an executable
|

can only confine new or already confined processes of that executable,
|
||||
but leaves already running processes unconfined.
