Check Text (C-52081r779505_chk)

Verify all files and directories on OL 8 have a valid group with the following command:

$ sudo find / -nogroup

If any files on the system do not have an assigned group, this is a finding.

Fix Text (F-52035r779506_fix)

Either remove all files and directories from OL 8 that do not have a valid group, or assign a valid group to all files and directories on the system with the "chgrp" command:

$ sudo chgrp <group> <file>
