Description
Misuse of the reboot command may cause availability issues for the system.

ℹ️ Check
Verify that OL 9 is configured to audit the execution of the reboot command with the following command: $ sudo auditctl -l \| grep reboot -a always,exit -F path=/usr/sbin/reboot -F perm=x -F auid>=1000 -F auid!=unset -k privileged-reboot If the command does not return a line or the line is commented out, this is a finding.

✔️ Fix
Configure the audit system to generate an audit event for any successful/unsuccessful uses of the reboot command by adding or updating the following rule in the "/etc/audit/rules.d/audit.rules" file: -a always,exit -F path=/usr/sbin/reboot -F perm=x -F auid>=1000 -F auid!=unset -k privileged-reboot The audit daemon must be restarted for the changes to take effect. Restart auditd: $ sudo service auditd restart
