AZLX-23-002185 - Amazon Linux 2023 must audit all uses of the shutdown command.

Information

Misuse of the shutdown command may cause availability issues for the system.

Solution

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
