Vulnerability discussion

To prevent unauthorized access or manipulation of system audit logs, the tools for manipulating those logs must be protected.

Check content

Verify the audit tool executables are group-owned by root, bin, sys, or system. Procedure: # ls -lL /sbin/auditctl /sbin/auditd /sbin/ausearch /sbin/aureport /sbin/autrace /sbin/audispd If any listed file is not group-owned by root, bin, sys, or system, this is a finding.

Fix text

Change the group-owner of the audit tool executable to root, bin, sys, or system. Procedure: # chgrp root

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.
