A Survey on the Security of European 5G Private Networks

The introduction of 5G networks has created opportunities for many vertical use cases through strong support for massive Internet of Things (IoT) connections with three main promises, i.e., massive machine type communications, enhanced mobile broadband and ultra-reliable low latency communications. With the enlarged network surface and the new technologies such as software-defined networking and network functions virtualization utilized to support the promised functionality, new security requirements have arisen. This paper focuses on private 5G networks and provides an overview of the security challenges they face along with a survey of approaches proposed for solving those challenges.
