Successful/unsuccessful uses of the shutdown command in RHEL 9 must generate an audit record.

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

To load the rules to the kernel immediately, use the following command:

$ sudo augenrules --load
