Verify Amazon Linux 2023 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-78096r1120287_fix)
Configure Amazon Linux 2023 so that the audit system generates 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
