Sounds like you want IMA+EVM, specifically IMA-appraisal. I've no experience with that in practice.

By all means, you're invited to mail me in private/give me a call. While I personally cannot help you I can refer you to people who does that for living. Disclosure, I've no connection to security consultunts other than working with some excellent ones, to which I can refer and they'll probably find you a good place to get your system secure. Remember, even world class security teams, like the ones who designed the X-Boxes missed some details and ended up with vulnerable system. If indeed a secure Linux is a priority, industry knows how to do that to some extent, but IMHO you need paid professional consultant, not general question in a public mailing list. In my view, what you're doing is akin to asking a public forum how to design a brakes system without any context. This is unlikely to end up well. I don't feel it's responsible from my side to just provide my limited knowledge without mentioning the problems with the general approach.
