SV-64097r1_rule System audit tool executables must not have extended ACLs.

Vulnerability discussion

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

Check content

Check the permissions of audit tool executables. # ls -l /sbin/auditctl /sbin/auditd /sbin/ausearch /sbin/aureport /sbin/autrace /sbin/audispd If the permissions include a '+' the file has an extended ACL, this is a finding.

Fix text

Remove the extended ACL from the file. # setfacl --remove-all [audit file]

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.
