The Multiple Independent Levels of Security (MILS) is a high-assurance security architecture. Its basic precept is that a modular approach to security will make software both more secure and also easier to certify. The architecture has several of several distinct components including a very small, trusted, high-assurance Separation Kernel. Only this small Separation Kernel runs in a processor’s unrestricted privileged mode. All other code runs in secure partitions that are controlled by the Separation Kernel.
