Fix Recommendation

-e 2

The audit daemon must be restarted for the changes to take effect.

$ sudo service auditd restart

Check Contents

Verify that OL 9 audit system configuration prevents unauthorized changes with the following command:

$ sudo grep "^\s*[^#]" /etc/audit/audit.rules | tail -1
-e 2

If the audit system is not set to be immutable by adding the "-e 2" option to the end of "/etc/audit/audit.rules", this is a finding.
