Amazon Linux 2023 must generate audit records for all account creations, modifications, disabling, and termination events that affect /var/log/lastlog.

GROUP ID: V-274097RULE ID: SV-274097r1120279

Without generating audit records specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.
