Vulnerability discussion

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

Check content

Determine if system audit tool executables have a mode more permissive than 0750. If any do, this is a finding. Audit tools include, but are not limited to, audit, auditcat, auditconv, auditpr, auditselect, auditstream, auditbin, and auditmerge.

Fix text

Many audit tools have SUID bit set. Before changing permissions on system audit tool executables, check the file permissions for SUID bits. Change the mode of system audit tool executables to 0750. #chmod 0750 or 4750 Document all changes made.

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.
