What your really driving at Marcus is developing software in a trusted manner.
Companies developing Firewall software should be evaluated by SEI for a
Capability Maturity Model (CMM) rating. Companies that are at
level 2 or level 3 of CMM have this kind of documentation, and already have in
place peer reviews. Also, you can use the Trusted Development Methodology (used
to be TSDM) and accomplish much of the same thing. Your right, the Orange Book
evaluations take entirely too long, so why not evaluate the development process,
and certify a product based on that evaluation? It won't get you a bullet proof
Firewall, or bullet proof software, but what will? Surely not an orange book
evaluation. Microsoft was given a C2 rating for Windows NT 3.1 *not* connected
to a network.
