Four primary dimensions of the access control problem are identified. They are 1 the physical level at which to apply control 2 the fineness of distinction applied to the term access 3 the meaning of the term user identification and 4 the degree of sophistication employed in automatically assigning sensitivity descriptions to derived data sets. Within the context of MacAIMS, the Project MAC Advanced Interactive Management System, the design of an access control system is presented which takes positions along these dimensions appropriate for controlling access in a Management Decision System. Particular attention is given to computing access characteristics of new data sets derived from existing sets. In addition, several classes of problems which the system cannot solve are presented.
