It is used by the majority of enterprises with more than 500 employees, and can implement mandatory access control (MAC) or discretionary access control (DAC). RBAC is sometimes referred to as role-based security.

Famous quotes containing the words access and/or control:

    The Hacker Ethic: Access to computers—and anything which might teach you something about the way the world works—should be unlimited and total.
    Always yield to the Hands-On Imperative!
    All information should be free.
    Mistrust authority—promote decentralization.
    Hackers should be judged by their hacking, not bogus criteria such as degrees, age, race, or position.
    You can create art and beauty on a computer.
    Computers can change your life for the better.
    Steven Levy, U.S. writer. Hackers, ch. 2, “The Hacker Ethic,” pp. 27-33, Anchor Press, Doubleday (1984)

    Knowledge in the form of an informational commodity indispensable to productive power is already, and will continue to be, a major—perhaps the major—stake in the worldwide competition for power. It is conceivable that the nation-states will one day fight for control of information, just as they battled in the past for control over territory, and afterwards for control over access to and exploitation of raw materials and cheap labor.
    Jean François Lyotard (b. 1924)
