On the synthesis and analysis of protection systems

Lawrence Snyder
1977 ACM SIGOPS Operating Systems Review  
The design of a protection system for an operating system is seen to involve satisfying the competing properties of richness and integrity.  ...  Achieving both requires the interplay of analysis and synthesis.
