Title

Amazon Linux 2023 must be configured to off-load audit records onto a different system from the system being audited via syslog. (Cat II impact)

Discussion

The auditd service does not include the ability to send audit records to a centralized server for management directly. However, it can use a plug-in for audit event multiplexor (audispd) to pass audit records to the local syslog server.

Fix Text
