Securing 5G and Evolving Architectures

Chapter 6

Securing Virtualized 5G Core Deployments

After reading this chapter, you should have a better understanding of the following topics:

• Threats in virtualized 5G packet core deployments

• Securing virtualized 5G packet core deployments

• Real scenario case study examples of virtualized 5G core threat surfaces and threat mitigation techniques

5G introduces service-based architecture (SBA) for 5G Core (5GC), which is designed for cloud-native deployment. This chapter will take you through the threat surfaces in virtualized 5G packet core Cloud-Native Function (CNF) deployments and mechanisms to mitigate the threats. The same threats and mitigation techniques would apply to the virtualized RAN CNF deployments as well, but as 5GC SBA architecture ...
