Vulnerability discussion

Audit_user is a sensitive file that, if compromised, would allow a malicious user to select auditing parameters to ignore his sessions. This would allow malicious operations the auditing subsystem would not log for that user.

Check content

Check /etc/security/audit_user permissions. # ls -lL /etc/security/audit_user If /etc/security/audit_user is more permissive than 0640, this is a finding.

Fix text

Change the mode of the audit_user file to 0640. # chmod 0640 /etc/security/audit_user

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.
