Towards Securing Availability in 5G: Analyzing the Injection Attack Impact on Core Network

Abstract

Abstract5G technology for mobile networking involves control communications to set up the radio channels and the authentication and security credentials. The control communications preceding the authentication and subscription verification remain vulnerable against the communication injection threats. We study the injection threats on control communications in 5G New Radio standard in 3GPP. From our 5G client-based implementation and experimentation against real-world networking, we analyze and measure the threat impact against the 5G service provider infrastructure of the core network. To secure 5G networking, our paper discusses about future research directions for increasing the understanding of such vulnerability/threat and for building greater security and availability for 5G networking against such wireless injection threats.
