Title

All files and directories contained in user home directories must be group-owned by a group where the home directory's owner is a member. (Cat II impact)

Discussion

If a user's files are group-owned by a group where the user is not a member, unintended users may be able to access them.

Check Content

Open a terminal session and enter the following commands to view the group ownership of the user’s directories and files. ls -l /Users (shows users directory) ls -lL /Users/ <each user directory> If any directory or file is not group owned by the user or a know users group, this is a finding.

Fix Text

chgrp <group with user as member> <file with bad group ownership>
