5G mobile networks: reviewing security control correctness for mischievous activity

Abstract

A mobile telecommunications network has arguably become a vital part of today’s critical communications infrastructure underpinning society’s interconnectedness. A mobile telecommunications network can be considered a critical communications infrastructure that has been built upon a complex set of network technologies. However, the migration in recent years from pre-5G to 5G network technologies has presented the mobile telecommunications network operators with not only several security-related challenges but also potential unfortunate risk exposure. A new approach called Control-Risk-Correctness (CRC) addresses the need for evaluating a complex mix of network technology and the associated trade-offs between security and risk. CRC simplifies the analysis by examining the mobile telecommunications network from the perspective of security control effectiveness and risk treatments. This article outlines the application of CRC when assessing a mobile telecommunication network and highlights direct risk mitigation treatments in an aim to increase security control effectiveness and decrease risk exposure. CRC usefulness will assist in the evaluation of existing networks and safeguarding new networks over the coming years.

Enhanced Network Reliability Following Emergency (E911) Calls

“…Therefore, this decision will play a significant role in keeping the high reliability of the emergency service call back. With reference to this, the Network will not put up 5G NR measurements because the UE would be focusing on LTE as a way of avoiding any unnecessary network handovers that could interfere with an impending E911 call [8]. Finally, the Network should not send RRC connection reconfigure messages in the ENDC NR cell addition or a UE relocation to another LTE EARFCN.…”
