Description
The audit system should have an action setup in the event the internal event queue becomes full so that no data is lost. Information stored in one location is vulnerable to accidental or incidental deletion or alteration.

Check Text (C-274070r1120198_chk)

Verify Amazon Linux 2023 audit system is configured to take an appropriate action when the internal event queue is full: $ sudo grep -i overflow_action /etc/audit/auditd.conf overflow_action = syslog If the value of the "overflow_action" option is not set to "syslog", "single", "halt" or the line is commented out, ask the system administrator (SA) to indicate how the audit logs are off-loaded to a different system or media. If there is no evidence that the transfer of the audit logs being off-loaded to another system or media takes appropriate action if the internal event queue becomes full, this is a finding.

Fix Text (F-78066r1120197_fix)

Configure Amazon Linux 2023 so that the audit system takes an appropriate action when the internal event queue is full. Edit the /etc/audit/auditd.conf file and add or update the "overflow_action" option: overflow_action = syslog The audit daemon must be restarted for changes to take effect.
