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

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.
