Misuse of the "reboot" command may cause system availability issues.

Check

Verify RHEL 10 is configured to audit the execution of the "reboot" command with the following command:

$ sudo auditctl -l | grep reboot
-a always,exit -S all -F path=/usr/sbin/reboot -F perm=x -F auid>=1000 -F auid!=-1 -F key=privileged-reboot

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

Fix

Configure RHEL 10 to generate audit records upon successful and 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

Restart the audit daemon with the following command for the changes to take effect:

$ sudo service auditd restart
