Abstract—In recent years, Network Function Virtualization (NFV) is an emerging key technology that has enabled network operators to change the way they build networks. The application of NFV improves the flexibility of the network and services, improves the operating efficiency, and reduces the operating costs. NFV reconstruction based on microservice architecture can speed up the software development cycle as well as decoupling software. This article first introduces the development process of NF from the physical equipment to the microservice based VNF. Then, we discuss the establishment of a trusted environment and the monitoring of the environment based on microservices which are the key security issues of NFV. Finally, we put forward some research challenges and future directions of NFV security based on microservices.

Index Terms—Microservice, network function virtualization, service chain, virtualized network function.
