The growth of interconnected objects through Internet of Things (IoTs) and Machine-To-Machine communication (M2M) is no doubt inevitable. The researchers have predicted that by 2020, around fifty billion objects throughout the world will be connected with each other with the help of internetwork of smart objects. With the number of networked objects, grows the number of cyber-crime threats. Forthcoming fifth generation of mobile communication will be the converged version of all the wired and wireless networking services and technologies. The heterogeneous networking approach gives rise to various cyber threats.
