Study of 5G and its security
The security threat landscape of 5G has grown enormously due to the unprecedented increase in types of services and in the number of devices. Therefore, security solutions if not developed yet must be envisioned already to cope with diverse threats on various services, novel technologies, and increased user information accessible by the network. This paper outlines the 5G network threat landscape, the security vulnerabilities in the new technological concepts that will be adopted by 5G, and provides either solutions to those threats or future directions to cope with those security challenges. A brief outline of the post-5G cellular technologies is also provided and their security vulnerabilities which are referred as Future Generations (XG) in this work. In brief, this paper highlights the present and future security challenges in wireless networks, mainly in 5G, and future directions to secure wireless networks beyond 5G.
More specifically, in Chapter 1, a brief introduction to 5G is given, basic relevant definitions are examined, but also a brief comparison is made with the latest generation of mobile communications (which continues to be used to this day) the 4G.
In Chapter 2, the 5G model is studied in more detail, in terms of the basic features it will provide to its users, referring to basic usage scenarios that will be possible. Furthermore, basic technologies that are expected to be used in 5G are being studied, as well as the effects that the use of 5G will have on the business and private sector (development and facilitation in everyday life).
In Chapter 3, a brief overview of the security provided by previous generations of mobile communications (1G, 2G, 3G, 4G) and more detail is refered to the security of 5G, focusing on its architecture, relevant security recommendations and its standardizations.
In Chapter 4, reference is made to the security of 5G, focusing on dense networks, studying security and privacy in them, in which cases it may be possible the interception and generally violate personal data.
In Chapter 5, we refer to XG networks, a future generation of wireless network, and analyze the enhancement of its security through new technological concepts. It describes how new technological concepts such as softwarization and virtualization of security, artificial intelligence technologies and blockchain can be used to secure future XG networks.
In conclusion, the work is completed with Chapter 6, with the conclusions regarding the steps that have been taken for the security of 5G to date, leaving some "open" thoughts - predictions for the future.
