  • Patent number: 7640429
    Abstract: An apparatus to implement role based access control which reduces administrative expenses associated with managing access in accordance with policies and roles. The apparatus includes a memory storing a first role based access control condition associated with an action and a subsystem executing an enforcement entity and a decision entity. In various forms, the two entities are independent entities. The enforcement entity receives a request for the action from a requestor with a role. Additionally, the enforcement entity communicates the role and the request to the decision entity for the decision entity's decision of whether the role satisfies the first condition. The decision entity then communicates the decision to the enforcement entity. Accordingly, the enforcement entity allows or denies the requester the action based on the decision made by the decision entity.
