DoShield Through SDN for IoT Enabled Attacks

Abstract

In the past few years there has been a tremendous increase in network attacks especially the Denial of Service and Distributed Denial of Service attacks. The attacker tries to send a number of packets to the victim site so as to make it unavailable to provide any service. Nowadays DoS attacks can be performed using IoT enabled devices too. The traditional network architecture is unable to handle such attacks which gave rise to Software Defined Network(SDN) as a solution. Software-defined networking is a network technology that provides central control over the network and thus manages network behavior dynamically through software via open interfaces. SDN plays a role to retain the heterogeneity in networks and objects by integrating into them a control solution that interacts with the SDN controllers. Although SDN provides promising solutions to many security problems, it is also exposed to new attacks targeting the data plane, control plane or the link connecting the two planes. This paper aims at the integration of IoT with SDN technology, the study of OpenFlow Protocol, different DoS attacks occurring on the layered SDN structure and the possible mitigation strategies to weaken the impact of those attacks on the network. For this purpose, we will be using a mininet simulator, OpenVSwitch(OVS) and Floodlight SDN controller.
