• The paper first analyzes today ’ s three main access control technologies ? discretionary access control ( dac ) , mandatory access control ( mac ) and role - based access control ( rbac ) , and then points out that the traditional dac and mac are unable to satisfy the enterprise ’ s demand for the unified resource access control . however , although rbac has many merits , it is essentially still a subject - based static authorization model , and lacks the enough flexibility , dynamic characteristics and scalability and cannot satisfy the enterprise ’ s demand for the unified resource access control completely . based on the analytical research for rbac ’ s improved models , the paper proposes the role and context - based access control ( rcbac ) model
