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/audit/audit_site.conf file to determine if syscalls handling kernel modules are audited. # egrep -i "admin|modload|moduload|modpath" /etc/audit/audit_site.conf All of the above syscalls must be defined in the file, otherwise this is a finding.

Fix text

Edit /etc/audit/audit_site.conf and add the admin, modload, moduload, and modpath syscalls to the list of events to be audited.

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.
