OL 9 must be configured so that successful/unsuccessful uses of the poweroff command generate an audit record.

Misuse of the poweroff command may cause availability issues for the system.

Verify that OL 9 is configured to audit the execution of the poweroff command with the following command:

$ sudo auditctl -l | grep poweroff -a always,exit -F path=/usr/sbin/poweroff -F perm=x -F auid>=1000 -F auid!=unset -k privileged-poweroff

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

Configure the audit system to generate an audit event for any successful/unsuccessful uses of the poweroff command by adding or updating the following rule in the "/etc/audit/rules.d/audit.rules" file:

-a always,exit -F path=/usr/sbin/poweroff -F perm=x -F auid>=1000 -F auid!=unset -k privileged-poweroff

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

Restart auditd: $ sudo service auditd restart
