challenges surfacing due to IP connectivity. Hence, new solutions and technologies
have always been sought to protect the network, user traffic and services. In this chapter, we will provide an overview of the new types of security threats, and then present
the solutions proposed for those threats.
5G will connect a critical infrastructure that will require more security to ensure
safety of not only the critical infrastructure but safety of society as a whole. For example, a security breach in the power supply systems can be catastrophic for all the electrical and electronic systems on which the society depends upon. Similarly, data is
critical in decision making and the data will be carried by the 5G network. Hence,
adequate measures are required to safeguard the data. Similarly, it is envisioned that
public safety systems will also be connected through 5G networks, hence it is more
critical to develop proper measures to secure not only the network but also the services using 5G networks as a communication medium. Therefore, it is suggested by the
Next Generation Mobile Networks (NGMN) [4] that 5G should provide more than
hop‐by‐hop and radio bearer security. The 5G design principles elaborated in Figure 4.1
outlines the need for highly elastic and robust systems. Such architectures must support the deployment and placement of security functions whenever required in any
network perimeter.
4.2 Overviews of Security Recommendations
and Challenges
The security threat vectors in 5G will be multi‐dimensional, right from the physical
interfaces up to the application interfaces, services in the clouds, and user information. 5G networks will connect critical infrastructures, interconnect societies and
