Securing Internet of Things with Software Defined Networking

We present a comprehensive survey on how SDN technology can provide security for the IoT environment. We analyze several recently proposed SDN architectures and assess their benefits and drawbacks, and we present a classification to help network security analysts and researchers choose the most appropriate security mechanism according to their security requirements. Additionally, we propose a role based security controller architecture (called Rol-Sec) for the SDN-IoT environment. Finally, we discuss future research challenges that should be addressed when deploying SDN-based solutions for improving IoT security.
