Check Text (C-221725r991589_chk)
Verify all files and directories on the system have a valid group.
Check the owner of all files and directories with the following command:
Note: The value after -fstype must be replaced with the filesystem type. XFS is used as an example.
# find / -fstype xfs -nogroup
If any files on the system do not have an assigned group, this is a finding.
Fix Text (F-23429r419248_fix)
Either remove all files and directories from the system that do not have a valid group, or assign a valid group to all files and directories on the system with the "chgrp" command:
# chgrp <group> <file>
