Software Defined IoT Security Framework

The requirements of the fifth generation of mobile communications technology (5G) present many challenges. Among others, it aims at improved support of device-to-device communication, lower cost, lower latency than 4G and lower battery consumption, for better implementation of the Internet of things (IoT). However, the connectivity of IoT devices gives rise to additional security and privacy concerns. Given the associated data proliferation and the integration of third-party applications, the access control management becomes an exceedingly complex task. Thus, a security model is needed. Few years ago, the "softwarization" invasion along with the network "virtualization" have led to a new network control paradigm and paved the way towards a global network operating system. In this paper, we discuss the IoT requirements in terms of security and privacy. Additionally, we propose an IoT software defined security framework.
