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.
