NFV and NFV-based Security Services

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.
