I checked out this Unix link. http://catb.org/~esr/jargon/html/U/Unix-conspiracy.html Does anyone "know" if there is a backdoor? I don't think it matters if it's labeled a conspiracy, because conspiracy theories are only labeled conspiracy by people who neither know if a theory is true or not. These people can't prove the theory to be true, but this doesn't prove the theory not to be true, thus they find themselves floundering in the realm of conspiracy. To prove a theory not true, you have to show why it would be impossible for the theory to be true, which would mean proving no back door could physically exist. Does anyone know how to prove Unix is not possible to have a backdoor or can anyone prove Unix does have a backdoor? I'm sure Microsoft and Apple would both create a backdoor atleast by covert government mandate, but how could we know for sure either way? That would require the logic above, prove a backdoor impossible or prove there is one. Now that I've set the subject matter at hand, here is my main question: what is the basic description of an OS design that logically ensures the highest amount of security? We are dealing with physical laws here, which are finite, so there is a solid logical answer. I'm looking for people to throw ideas for discussion here, as well as intelligently critique others ideas. Here's my whack at it: Create an open source, simplistic Protect OS that you can sit Unix and other systems on top of. All protected files would be on the partition of the Protect OS without a backdoor. Now I'm sure the processor still could recieve commands in any case to read a "protected partition", but this is where encrytion and a physical start up disk should guard pretty well against that. As well as a buffer zeroing function for added security. Let me know your ideas and your critiques.
