Discussion

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.

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.
