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
information. In the third generation (3G) wireless networks, IP‐based communication
enabled the migration of Internet security vulnerabilities and challenges in the wireless
domains. With the increased necessity of IP‐based communication, the fourth Generation
(4G) wireless networks enabled the proliferation of smart devices, multimedia traffic,
and new services into the mobile domain. This development lead to a more complicated
and dynamic threat landscape. With the advent of the fifth generation (5G) wireless
networks, the security threat vectors will be bigger than even before, with greater concerns for privacy [3].
One haunting fact that has always stayed alive during the development towards the
5G is that the IP‐based communication not only increased the variety of services
and network traffic but opened new doors to develop new cracking and hacking
mechanisms for wireless networks and mobile devices. Wireless networks and user
equipment, however, had difficulty in keeping up the pace with the increasing security
