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>).
|
||||
Security-minded users may also want to enable <xref linkend="opt-security.apparmor.killUnconfinedConfinables"/>,
|
||||
at the cost of having some of their processes killed
|
||||
when updating to a NixOS version introducing new AppArmor profiles.
