OL 9 must label all offloaded audit logs before sending them to the central log server.

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

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.

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
