Hello Mesut,
Distributed File System (DFS) service does not implement any additional security measures, beyond what the Windows Server and NTFS provides. Permissions to a target are not related to the DFS topology. Security is enforced by the underlying file system when a user tries to access a target and its contents. To maintain security, you should use NTFS and file sharing permissions to secure any shared folders used by DFS so that only authorized users can access them.
Hope this helps,
Mike
