Abstract
Adapting Software Defined Networking (SDN) raises many challenges including scalability and security on the Internet of Things (IoT) network. Growing network size increases resulting in the network load in the SDN controller and facing security challenges. Distributed Denial of Service (DDoS) attacks are among the most acute threats in the present scenario. The attack scenario and security of multiple controller networks are simulated and evaluated in this research. Simulation has been conducted in Mininet-SDN emulator, hosting OS was Ubuntu Linux, Wireshark was used for analysing the network traffic, support vector machines were used to classify the traffic flows. DDoS attacks were detected, and mitigation has been done using a support vector machine learning-based approach. The results show that the support vector machine's sensitivity, specificity and accuracy are excellent in the range of 98.7% to 98.8%. Security solutions are fast and effective in mitigating DDoS attacks.
