On hierarchical design of computer systems for critical applications
Sept. 1986 (vol. 12 no. 9)
pp. 905-920
Peter Gabriel Neumann, SRI International, Menlo Park, CA 94025
We consider here the design of computer systems that must be trusted to satisfy simultaneously a variety of critical requirements such as human safety, fault tolerance, high availability, security, privacy, integrity, and timely responsiveness — and to continue to do so throughout maintenance and long-term evolution. Hierarchical abstraction provides the basis for successive layers of trust with respect to the full set of critical requirements, explicitly reflecting differing degrees of criticality.
