AZLX-23-002220 - Amazon Linux 2023 must off-load audit records onto a different system in the event the audit storage volume is full.

Information

Information stored in one location is vulnerable to accidental or incidental deletion or alteration.

Off-loading is a common process in information systems with limited audit storage capacity.

Solution

Configure Amazon Linux 2023 to off-load audit logs in the event the audit storage volume becomes full.

Add or update the following line (depending on configuration "disk_full_action" can be set to "SYSLOG" or "SINGLE" depending on configuration) in "/etc/audit/auditd.conf" file:

disk_full_action = SYSLOG
