DESIGN OF A ZONE-BASED ROLE MODEL FOR ACCESS CONTROL

The study is dedicated to developing a role-based access control model with a zone-based security policy. The authors suggest a role-based access control model with intra-zonal security policy that involves an enabled set of accesses to the objects of other zones in terms of the objects held by the zone, and allows to describe the mediation of access to information resources of computer systems adequately. In the proposed model remote user agents gain access to the objects by the rules and policy regulations of the zones where access objects are located.
