This paper brings together a formal predicate‐based model of protection and a relational approach to a protection database within the modular architecture of MULTISAFE. An implementation model is developed for the management of stored representations of authorization information. Classes of access decision dependency are reviewed, and protection policies, design decisions, and some implementation problems are discussed. Detailed examples are used to illustrate the use of this flexible and generalized approach to database security within the MULTISAFE system architecture.
