• Any resource is identified by an authority DFS User. Any resource and policy concerning resources is identified by and submitted to the unconditional authority of a unique DFS User.
• Any action upon a resource has an agent DFS User. The agent of any action concerning resources is ultimately attributed to a single DFS User. This facilitates the accountability of users for their actions and simplifies resource access control.
• Any action upon a resource is a transaction between an agent user and an authority user. Any resource manipulating action is equivalent to a transaction between the agent of the action and the authority of the resource. The agent must acquire the permission of the authority in order to successfully perform the action.
