One aspect of producing secure operating systems involves the confinement of programs. This paper discusses the program confinement problem as addressed by the developers of a retrofitted version of the IBM VM/370 virtual machine monitor. This version of the system (called KVM/370) uses a security-kernel architecture to provide a provably secure multi-level environment for Department of Defense computer operations.
