Preventive Determination and Avoidance of DDoS Attack with SDN over the IoT Networks

The Internet of Things (IoT) is growing increasingly along with the development of security issues. The IoT system is unable in protecting against ransomware and various forms of malicious threats. The way a vast number of IoT devices are treated is uncomfortable and insecure. Security problems have become increasingly important with the spread of IoT devices. The Software-Defined Networking (SDN) paradigm provides a way to control IoT devices securely. For the IoT paradigm, we have suggested a general system for detecting and mitigating Distributed Denial-of-Service (DDoS) attacks using an SDN. The proposed architecture consists of a pool of controllers comprising SDN controllers, IoT gateway-integrated. Also, we have offered an IoT DDoS attack detection and mitigation algorithm attached to the proposed SDN IoT platform. Finally, the proposed algorithm shows the experimental results that have improved performance and the proposed architecture adapts to heterogeneous and fragile devices to enhance IoT security.
