4.1 Introduction

The vision of the 5G wireless networks lies in providing very high data rates, higher coverage through dense base station deployment with increased capacity, significantly better Quality of Service (QoS), and extremely low latency [1]. 5G is considered to provide broadband access everywhere, entertain higher user mobility, enable connectivity of a massive number of devices (e.g. IoT), and the connectivity will be ultra‐reliable and affordable [2]. The development towards an all‐IP‐based communication, for example in 4G, has already helped develop new business opportunities, provide new online services and connect industrial machines, home appliances and business units. However, with this development, the security challenges and threat vectors have also increased.

Wireless communication systems were prone to security vulnerabilities from the very beginning. In the first generation (1G) wireless networks, mobile phones and wireless channels were targeted for illegal cloning and masquerading. In the second generation (2G) of wireless networks, message spamming became common, not only by pervasive attacks but also by injecting false information or broadcasting unwanted marketing ...
