Internet of Things (IoT) is an integral part of the journey towards the smart world that transforms isolated individual things into an assemblage that communicate with each other to perform smart activities. Due to the exponential growth in the number of connected devices in IoT and the heterogeneous network requirements of different IoT applications, existing telecommunication architectures require a revolutionized re-engineering transfiguration. Hence, the future telecommunication networks are peculiarly designed to facilitate the connectivity requirements of IoT. Network slicing is a revolutionary technology in future networks that divides the physical network into multiple logical networks, known as network slices, which facilitate heterogeneous network requirements of different applications by allocating different network slices. Thus, network slicing is one of the key enabling technologies for IoT realization in the future. Typically, IoT devices are vulnerable to attacks such as Distributed Denial of Service (DDoS) attacks, IoT botnets, Zero-day attacks, and Man in the Middle (MITM) attacks. Predominantly, IoT devices are resource constraint elements. Thus, implementing complex security mechanisms within IoT devices are not feasible. Moreover, the heterogeneity of IoT devices and services are urging specialized and unique security mechanisms in contrast to generic solutions. These aspects intensify the importance of an off-device solution for IoT security. When facilitating diverse security requirements of different IoT applications across network slices, identifying the optimal security mechanisms that ensure both Security Service Level and Service Level Agreements is an arduous activity. Therefore, this research will be focused on developing a security framework for network slicing to improve IoT security.
