Policy-based Role and Access Modeling

In this paper, we present an approach based on Attribute Based Access Control (ABAC) and Risk Adaptive Access Control (RAdAC) to improve the reliability of the risk assessment and authorization process. The model has been designed to adapt to the complex and ever-changing nature of modern campus networks by incorporating location information. This added layer of risk assessment enhances the ABAC model by adding a level of authorization to it.
