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. When audit logs are not labeled before they are sent to a central log server, the audit data will not be able to be analyzed and tied back to the correct system. Satisfies: SRG-OS-000039-GPOS-00017, SRG-OS-000342-GPOS-00133, SRG-OS-000479-GPOS-00224

Check Content

Verify that OL 9 Audit Daemon is configured to label all offloaded 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 OL 9 to label all offloaded audit logs before sending them to the central log server.

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.

Restart auditd:
$ sudo service auditd restart
