Title

The audit records must be off-loaded onto a different system or storage media from the system being audited. (Cat II impact)

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.

Check Content

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.

Fix Text

Configure the audit system to off-load audit records to a different system or storage media from the system being audited. Set the "remote_server" option in "/etc/audisp/audisp-remote.conf" with the IP address of the log server. See the example below. remote_server = 10.0.1.2 In order for the changes to take effect, the audit daemon must be restarted. The audit daemon can be restarted with the following command: # sudo systemctl restart auditd.service
