The Orange Book. Trusted Computer System Evaluation Criteria (TCSEC) is a United States Government Department of Defense (DoD) standard that sets basic requirements for assessing the effectiveness of computer security controls built into a computer system.
For example, the Trusted Computer System Evaluation Criteria was referred to as "The Orange Book." [ 1 ] In the book entitled Applied Cryptography , security expert Bruce Schneier states of NCSC-TG-021 that he "can't even begin to describe the color of [the] cover" and that some of the books in this series have "hideously colored covers."
The Orange Book, another classic computer security literature reference, therefore provides [3] a more formal definition of the TCB of a computer system, as the totality of protection mechanisms within it, including hardware, firmware, and software, the combination of which is responsible for enforcing a computer security policy.

Multiple Independent Levels of Security/Safety (MILS) is a high-assurance security architecture based on the concepts of separation [1] and controlled information flow. It is implemented by separation mechanisms that support both untrusted and trustworthy components; ensuring that the total security solution is non-bypassable, evaluatable, always invoked, and tamperproof.
