Vulnerability discussion

Failure to give ownership of system configuration files to 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

Open a terminal session and enter the following command to verify the group ownership of the /etc/services file. ls -lL /etc/services If the /etc/services file is not group owned by wheel, this is a finding.

Fix text

Open a terminal session and enter the following command to set the group. chgrp wheel /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.
