The Common Criteria evaluates the security of systems largely in terms of how they are built, and additionally with respect to what features they provide. For instance, it is a CC requirement that all source code be under revision control. This requirement in itself effectively makes it near impossible to certify a full Linux distribution, because the code base for the hundreds of packages are maintained independently. >The Orange Book probably came closest, but seemed largely unworkable, judging by its breadth of application: I believe only one system was ever certified A1, > This is also not true. According to the NSA Evaluated Products List <http://www.radium.ncsc.mil/tpep/epl/epl-by-class.html>, two "network components" have been evaluated A1, while *zero* operating systems and applications have made A1. > and the most commonly applied level, C2, is so ridiculously trivial that it was even awarded to Windows (albeit NT, not 95). > Yeah; C2 pretty much requires that you show up for the meeting, and bring a check :-) > Personally, I have very little faith in proof of correctness (a baase requirement for A1), as most proofs tended to be larger than the code they were trying to prove. > I agree with that. All of which supports my point: early standardization is a disaster. The Orange Book tried to standardize a discipline that is still not well understood, resulting in a standard that is overly expensive and underly effective, and therefore largely irrelevant to the real world.
