Extended Security in Heterogeneous Distributed SDN Architecture

Abstract

With the rapid growth in the network, a demand for more flexible and secure technology of network programmability is increasing. With the introduction of technology like SDN, a new platform for communication evolved which is free from traditional network barriers like vendor lock-ins, limited scope for innovation, buggy software, etc. No doubt, SDN has solved these problems but SDN security issues are of major concern. SDN security is the key research area that is gaining popularity. Our paper discusses SDN security challenges. In our experiments, we tried to depict the network performance and utilisation of resources in case of security attacks. With the aim of securing SDN in the case of heterogeneous distributed SDN controllers, we suggested a routing protocol that manages routing tasks where TLS security has been embedded in the header for OpenFlow packet. We simulated the system with our testbed of virtual machine with different attacks scripted in python.
