Keynote 3: 5G Security: Navigating the Changing Threat Landscape
The mobile telecommunications industry is under significant threat. As we move towards the 5G era of intelligent connectivity, the threat posed by cyberattacks is increasing as the industry diversifies its services. With so many more connected devices, the attack surface will be exponentially higher. Increased attention from legislators, media and consumers is amplifying the public scrutiny of security. 5G standards outline standardised security architecture that offers controls surpassing those of previous generations. However, we face the threat of repeating mistakes of the past. The use of Diameter in 4G resulted in numerous vulnerabilities being introduced to the operator’s networks. With the intention to use IP based protocols in 5G we face the threat of choosing an insecure signalling service protocol. The GSMA predict that the additional complexity 5G will add to the network has the potential to increase alarm fatigue within security operations teams, leading to attackers going unnoticed for longer periods of time, unless emerging technologies such as artificial intelligence (AI) can be harnessed to transform and increase the efficiency of security operations centres. This session will explore how operators can navigate the changing threat landscape as they move into the 5G era.
