Security of Software Defined Networks (SDN)

Software defined networking (SDN) is a developing technology which completely changes the architecture and working of traditional networks. There has been growing urgency among networking developers to come up with a new set of devices to support Software Defined Networks and to implement better services in SDN compared to traditional networks. During these activities, security of the packets in the SDN networks comes into debate. In this paper, we describe the security of the SDN networks by implementing the SDN topology using the Mininet tool and explain the security vulnerabilities in the SDN networks. We describe the implementation of the DDOS attack using IP spoofing and Man in the Middle attack (MITM) using Arpspoof on the SDN topology and explain the behavior of SDN networks against these security attacks. We proposed the security method to provide security for SDN networks against the security attacks like DDOS, Man in the Middle (MITM), ARP spoofing, Replay, IP spoofing and the modification of information attacks.
