Abstract


Access control administration regulates and enforces the definition of the components of an access control system by authorized administrative users. The shortcomings of classical access control models, as they are applied in today’s Web-based applications that are commonly used in collaborative and distributed enterprise environments, can effectively be addressed by dynamic administration. In this paper, the implementation and application of the DARBAC (Dynamically Administering Role Based Access Control) model in the banking sector is demonstrated. By this demonstration, the benefits that are related to improvements in the administration of role-based access control (RBAC) and provision of tight and just-in-time access control without jeopardizing the simplicity of administration are clearly revealed.
