Assessment Procedure

Check Text

To determine if the system is configured to audit changes to its SELinux configuration files, run the following command:

$ sudo grep -w "/etc/selinux" /etc/audit/audit.rules

If the system is configured to watch for changes to its SELinux configuration, a line should be returned (including "-p wa" indicating permissions that are watched).

If the system is not configured to audit attempts to change the MAC policy, this is a finding.

Implementation Procedure

Fix Text

Add the following to "/etc/audit/audit.rules": 

-w /etc/selinux/ -p wa -k MAC-policy
