Extracting and ranking for the threats of the radio access network layer of the ۵th generation mobile network base on risk analysis

The fifth generation of mobile networks (۵G) offers new and advanced services such as virtual/augmented reality (AR/VR), high-quality video streaming, remote surgery, Internet of Things (IoT), and smart cars with stringent requirements. In this article, we review the ۵G architecture and then focus on the Radio Access Network (RAN) architecture, and collect the threats, vulnerabilities, and security solutions provided by researchers and academic authorities in this field. In this article, we also rank RAN threats in the ۵G network. To rank threats, we assign a score to each threat by introducing a risk criterion, and finally, we analyze the risk by assessing the impact/severity and probability of success of the threats on the ۵G network, so that we can provide a good ranking for the threats. The results of our studies and analyses in this article inform ۵G network operators which threats should be prioritized. The results of this paper will guide to secure the ۵G network and deploy security solutions.
