13. ABSTRACT

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 tern "access"; 3) the meaning of the term "user identification";
and 4) the degree of sophistication employed in automatically assigning sensi-
tivity 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 ~ecision
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.
