Fix Recommendation

Configure OL 9 to generate audit records for all account creations, modifications, disabling, and termination events that affect "/etc/sudoers".

Add or update the following file system rule to "/etc/audit/rules.d/audit.rules":

-w /etc/sudoers -p wa -k identity

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

Restart auditd:
$ sudo service auditd restart

Check Contents

Verify that OL 9 generates audit records for all account creations, modifications, disabling, and termination events that affect "/etc/sudoers" with the following command:

$ sudo auditctl -l | grep /etc/sudoers
-w /etc/sudoers -p wa -k identity
-w /etc/sudoers.d -p wa -k identity

If the command does not return a line or the line is commented out, this is a finding.
