security levels, V.4

[Benson I. Margulies]

Randall at virginia is misinformed:

a B2 system has two things that no C system has (other than
labels)
1) trusted path:

2) an implementation that passed must stricter muster with the DODCSC.
B2 systems have to have full design documentation and meet some modularity
standards. C systems just sort of have to have the features.

Curious individuals should acquire copies of the orange book and 
see for themselves.
