Vulnerability discussion

If a user can write to the audit logs, then audit trails can be modified or destroyed and system intrusion may not be detected.

Check content

Inspect the auditing configuration file, /etc/rc.config.d/auditing, to determine the filename and path of the audit logs. The entries should appear similar to the following: PRI_AUDFILE=/var/.audit/file1 SEC_AUDFILE=/var/.audit/file2 # egrep “PRI_AUDFILE|SEC_AUDFILE” /etc/rc.config.d/auditing For each audit log directory/file, check the permissions. # ls -lLd # ls -lLa If any audit log directory/file permissions include a “+”, this is a finding.

Fix text

As root, remove the ACL. # chacl -z # chacl -z

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.
