Check Text ( C-61955r926627_chk )
Verify that RHEL 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-61879r926628_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.
