SV-26524r1_rule The audit system must be configured to audit the loading and unloading of dynamic kernel modules.

Vulnerability discussion

Actions concerning dynamic kernel modules must be recorded as they are substantial events. Dynamic kernel modules can increase the attack surface of a system. A malicious kernel module can be used to substantially alter the functioning of a system, often with the purpose of hiding a compromise from the SA.

Check content

Check /etc/security/audit_control file. # grep flags /etc/security/audit_control If the as element is missing from the flags line, this is a finding.

Fix text

Edit /etc/security/audit_control and add the as flag to the flag parameter.

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.
