Title

Amazon Linux 2023 must label all off-loaded audit logs before sending them to the central log server. (Cat II impact)

Discussion

Enriched logging is needed to determine who, what, and when events occur on a system. Without this, determining root cause of an event will be much more difficult.

Check Content

Verify Amazon Linux 2023 is configured so that the Audit Daemon labels all off-loaded audit logs with the following command: $ sudo grep name_format /etc/audit/auditd.conf name_format = hostname If the "name_format" option is not "hostname", "fqd", or "numeric", or the line is commented out, this is a finding.

Fix Text

Configure Amazon Linux 2023 to be configured so that the Audit Daemon labels all off-loaded audit logs. Edit the /etc/audit/auditd.conf file and add or update the "name_format" option: name_format = hostname The audit daemon must be restarted for changes to take effect.
