Detection and Mitigation of MITM Attack in Software Defined Networks

. Software Defined Network (SDN) is the networking architecture that segregates the activities of the control plane from the data plane. Man In The Middle (MITM) is a type of digital attack in a network where the attacker utilizes duplicated ARP messages by spoofing the attacker’s MAC address with the authorized user’s IP address. This paper sorts out the ARP spoofing, which is the suite of MITM attacks using IP-MAC address bindings. SDN is emulated using Mininet and the MITM attack over this network is done using arpspoof, which is the segment of the tool named Dsniff. For the evaluation of the proposed algorithm, various network parameters are compared and analyzed in both RYU and POX controllers. As a result, the proposed algorithm mitigates the MITM attack successfully by dropping the attacked packets.
