An Access Control Model based on the concepts of Organization and Service for Large Infrastructures

We present in this paper a new access control model for large infrastructures, S-OrBAC (Service Organization Based Access Control), based on the two fundamental concepts that are Organization and Service. The need for access control systems in large infrastructures is motivated by the business growth and the expansion of user’s connection to different resources and data. We provide a general view on the concept of service within large infrastructures, and then introduce the different entities of the model S-OrBAC. Finally, we give a use case application for the model in a university establishment providing multiservice.
