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).

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.
