Major Security Challenges in 5G Network

With innovative technology concepts, 5G networks will meet broadband access requirements everywhere. Achieve high user and device mobility and connectivity for many devices (such as the Internet of Things) in a highly reliable and cost-effective manner. Software-defined networking and network functions virtualization leveraging the developments in cloud computing such as mobile edge computing is the most spoken out technologies to meet these requirements. Security has ended up an essential concern in many telecommunications businesses nowadays as dangers can have high consequences. Particularly, as the center and empower advances will be related with the 5G arrange, the secret data will move at all layers in future remote frameworks. However, firmly using these technologies and providing user privacy & more security in future wireless networks are the new major concerns. Hence, in this paper, we tried to provide an overview of security challenges in clouds, software-defined networking, and network function virtualization. This paper further deliberates the new security features involving different technologies applied to 5G, like device-to-device communications, heterogeneous networks, massive multiple-input multiple-output, software-defined networks, and the Internet of Things. Henceforth, we’ll try to demonstrate the solutions of the present to these challenges and future directions for secure 5G systems strongly
