Abstract: The requirements for the efficient management of authorisations in web-based collaborative applications lead to new access control administration paradigms during run-time. The need for fine-grained and just-in-time access control can effectively be addressed by dynamic administration of authorisations, via either proper role or permission activation. In this paper, an authorisation architecture that is based on the Dynamically Administering Role-based Access Control (DARBAC) model, and provides access control and meta-access control capabilities, is presented. The paper describes the implementation of the components and the structure of the architecture within the .NET framework. The application of the implemented access control system is also demonstrated. Based on the results of this demonstration, a more detailed investigation of the benefits of the proposed approach, which are related to improvements in the administration of Role-based Access Control (RBAC) during run-time, is presented.
