SV-63657r1_rule The file integrity tool must be configured to verify ACLs.

Vulnerability discussion

ACLs can provide permissions beyond those permitted through the file mode and must be verified by file integrity tools.

Check content

If using an Advanced Intrusion Detection Environment (AIDE), verify that the configuration contains the "ACL" option for all monitored files and directories. Procedure: Check for the default location /etc/aide/aide.conf or: # find / -name aide.conf # egrep "[+]?acl" If the option is not present. This is a finding. If using a different file integrity tool, check the configuration per tool documentation.

Fix text

If using AIDE, edit the configuration and add the "ACL" option for all monitored files and directories. If using a different file integrity tool, configure ACL checking per the tool's documentation.

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.
