Title

The audit event multiplexor must be configured to off-load audit logs 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 event multiplexor is configured to off-load 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 active /etc/audisp/plugins.d/au-remote.conf active = yes If "active" is not set to "yes", 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. If there is no evidence that the system is configured to off-load audit logs to a different system or storage media, this is a finding.

Fix Text

Configure the audit event multiplexor to off-load audit records to a different system or storage media from the system being audited. Set the "active" option in "/etc/audisp/plugins.d/au-remote.conf" to "yes": active = yes 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
