Access Control Based Dynamic Path Establishment for Securing Flows from the User Devices with Different Security Clearance

Abstract

<p>In this work, we proposed Software Defined Networking (SDN) based access control techniques for preventing unauthorised access to traffic flows in secure networks. We have developed an Access Control Application (ACA) for the SDN Controller for differentiating the flow requests from the user/devices that are classified at different security levels and configuring the routes with physical or virtual separation between the flows. This separation of flows makes it difficult for the malicious users with lower security clearance to access the flows that belong to the users with higher security clearance. Hence, our work significantly minimises the attack surface in secure environments. We will also discuss the prototype implementation of our model and some performance characteristics.</p>
