Mitigating attacks in Software Defined Network (SDN)

Abstract

Software Defined Network (SDN) is disruptive networking technology. In this paper, we will address some of the major vulnerable areas in SDN. We express some of the unique ways that an adversary can use to attack either the SDN controller or the communication devices. We have used a policy based approach to mitigate these attacks towards the SDN domain. We have implemented our Policy Based approach as an SDN application. ONOS an Open Source SDN controller is used to develop the Policy based Security Application. Finally, we will justify the application using real time attack scenarios. We will express how the policy expressions help to mitigate attacks and represent the performance comparison.
