SV-64473r1_rule All network services daemon files must not have extended ACLs.

Vulnerability discussion

Restricting permission on daemons will protect them from unauthorized modification and possible system compromise.

Check content

Check network services daemon files have no extended ACLs. # ls -la /usr/sbin If the permissions include a '+', the file has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding. Note: Network daemons not residing in these directories must also be checked.

Fix text

Remove the extended ACL from the file. # setfacl --remove-all /usr/sbin/*

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.
