Check Text (C-221724r991589_chk)
Verify all files and directories on the system have a valid owner.
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 -nouser
If any files on the system do not have an assigned owner, this is a finding.
Fix Text (F-23428r419245_fix)
Either remove all files and directories from the system that do not have a valid user, or assign a valid user to all unowned files and directories on the system with the "chown" command:
# chown <user> <file>
