The role of formal modeling in the study of capability- based protection systems is explained. Historical background is presented and a model of a computer science department's computer system is presented. A survey of several important capability-based models is given including the Harrison, Ruzzo, Ullman model, the Take-Grant model, and grammatical models. These models are presented in a unified manner with consistent terminology. The main results of the models are given. These results are compared, contrasted, and interpreted in the context of numerous examples.
