SDN-Based Secure Architecture for IoT

摘要

Internet of things (IoT) means connecting things through the internet. The growing market for IoT also attracts malicious individuals trying to gain access to the marketplace. Security issues are among the most significant worries in companies that rely on the cloud of things to do business. SDN-based architecture has improved the security of IoT networks. The centralized controller is responsible for managing the critical network's operations, and growing the network size increases the network load in the controller. Controllers in SDN-based architecture are still facing security challenges such as unauthorized access, configuration issues, distributed denial of service (DDoS) attacks, and a man-in-the-middle (MITM) attacks. The attack scenario and security of SDN-based IoT networks are evaluated in this research. The simulation results show that the proposed approach and security solutions are fast and effective in mitigating the attacks.
