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. One method of off-loading audit logs in Oracle Linux is with the use of the audisp-remote dameon. 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-000342-GPOS-00133, SRG-OS-000479-GPOS-00224

ℹ️ Check
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, ask the System Administrator to indicate how the audit logs are off-loaded to a different system or storage media, and to indicate if the logs are labeled appropriately. If there is no evidence that the system is configured to off-load audit logs to a different system or storage media, or if the configuration does not appropriately label logs before they are off-loaded, this is a finding.

✔️ 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
