I agree combinatorial is probably a better factor of growth of possible security errors. Maybe an algorithm like Port Numbers Open factorial times the number of applications on those ports factorial times number of code lines ! = number of possible bugs-vulnerabilities. Apps! * Ports! * Code Lines! = Possible Security Vulnerabilities or some combinatorial proof a! * p! * c ! = s. Call it the the Clairmont-Everhart Security Index of Vulnerability. The CSIV number, Nice point. Factor in code lines too 8->, oh well so much for my dreams of being a mathematician. Anyone done this? I think there can ever be enough testing, and I think if someone is dedicated enough an exploit can be found. I just think a system becomes so hardened that the effort to exploit it or break it becomes too onerous to do. Where as 1 billion monkeys pushing keys, someone is going to stumble onto something, a key sequence timing error or other weird combination of events that finds another bug or security hole.
