15.1 Introduction
In this chapter, we discuss 5G and security in the context of Network Functions
Virtualization (NFV), a new transformative technology that combines the technology
developments in distributed systems, software virtualization, and cloud computing to
modernize telecommunication infrastructure and services. We will cover the content in
three parts. The first part will discuss what NFV is and how NFV relates to 5G and
security. In the second part, we survey the new security challenges that NFV brings
and the new opportunities to solve security problems using NFV technologies. In the
third part, we look at several exciting advancements in NFV‐based security solutions
that can have a huge impact on the success of 5G and networking in general.
15.2 5G, NFV and Security
5G is both a quantitative and qualitative great leap forward for the wireless industry.
While the standardization and planning of early commercial deployments are just
getting under way at the time of writing, the goals that the industry set are very ambitious and far‐reaching. For example, the NGMN Alliance white paper [1] broadly
defined the characteristics of 5G in three aspects:
1) Use cases, faster and more common broadband access, IoT, vehicular networks,
verticals like healthcare and robotics, ultra‐real‐time tactile networks, AR/VR;
2) Business models, XaaS, value‐add services and OTT applications; and
3) Value creation, encompassing diverse sets of value propositions to different customers
ranging from consumers and enterprises to many vertical markets and partners.
The white paper systematically examined the requirements of 5G from user, system
and business perspectives:
● User experiences: high data throughput, low latency;
● System performance: high user density, spectrum efficiency;
