Security of a computer system frequently considers location and time of requesting an access as important factors for granting or denying the request. The security policy specified for such systems should include formalism for representing spatial and temporal facts. Existing security policy specifications already consider useful temporal facts like Monday, Weekends, College hours, etc. We have taken a new approach for representing real world spatial objects in security policy. The proposed representation uses six policy connectives at,inside,neighbor,is,crosses,overlappingfor expressing useful relations existing between practical spatial entities like office, department, roads, etc. The expressiveness of the connectives has been discussed and a formalism for combined spatiotemporal interaction has also been proposed in this paper.
