Vulnerability 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, 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

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
