Verify that OL 9 is configured to audit the execution of the shutdown command with the following command:
$ sudo auditctl -l | grep shutdown
-a always,exit -F path=/usr/sbin/shutdown -F perm=x -F auid>=1000 -F auid!=unset -k privileged-shutdown
If the command does not return a line or the line is commented out, this is a finding.
Fix Text (F-75533r1092569_fix)
Configure the audit system to generate an audit event for any successful/unsuccessful uses of the shutdown command by adding or updating the following rule in the "/etc/audit/rules.d/audit.rules" file:
-a always,exit -F path=/usr/sbin/shutdown -F perm=x -F auid>=1000 -F auid!=unset -k privileged-shutdown
The audit daemon must be restarted for the changes to take effect.
Restart auditd:
$ sudo service auditd restart
