The Red Hat Enterprise Linux operating system must label all off-loaded audit logs before sending them to the central log server.

Description

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. 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.

Check Text ( C-80737r1_chk )
Verify the audisp daemon is configured to label all off-loaded audit logs: # grep "name_format" /etc/audisp/audispd.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 (F-87855r2_fix)
Edit the /etc/audisp/audispd.conf file and add or update the "name_format" option: name_format = hostname The audit daemon must be restarted for changes to take effect: # service auditd restart
