The Oracle Linux operating system must be configured so that all files and directories have a valid owner.

Unowned files and directories may be unintentionally inherited if a user is assigned the same User Identifier (UID) as the UID of the un-owned files.

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.

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>
