  Orange Book
       
           A standard from the US Government
          National Computer Security Council (an arm of the
          U.S. National Security Agency), "Trusted Computer System
          Evaluation Criteria, DOD standard 5200.28-STD, December 1985"
          which defines criteria for trusted computer products.  There
          are four levels, A, B, C, and D.  Each level adds more
          features and requirements.
       
          D is a non-secure system.
       
          C1 requires user log-on, but allows group ID.
       
          C2 requires individual log-on with password and an audit
          mechanism.  (Most Unix implementations are roughly C1, and
          can be upgraded to about C2 without excessive pain).
       
          Levels B and A provide mandatory control.  Access is based on
          standard Department of Defense clearances.
       
          B1 requires DOD clearance levels.
       
          B2 guarantees the path between the user and the security
          system and provides assurances that the system can be tested
          and clearances cannot be downgraded.
       
          B3 requires that the system is characterised by a mathematical
          model that must be viable.
       
          A1 requires a system characterized by a mathematical model
          that can be proven.
