Vulnerability discussion

Failure to give ownership of system configuration files to root or a system group provides the designated owner and unauthorized users with the potential to change the system configuration which could weaken the system's security posture.

Check content

Check the group ownership of the services file. Procedure: # ls -lL /etc/services If the file is not group-owned by bin, sys, or system, this is a finding.

Fix text

Change the group owner of the services file. Procedure: # chgrp system /etc/services

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.
