Verify the audit system off-loads audit records to a different system or storage media from the system being audited. Check that the records are being off-loaded to a remote server with the following command: # sudo grep -i remote_server /etc/audisp/audisp-remote.conf remote_server = 10.0.1.2 If "remote_server" is not configured, or the line is commented out, this is a finding.
