Security for 5G: What are the new threat vectors and solutions?

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. 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.

According to GSMA Intelligence, there will be 25 billion IoT connections by 2025 – digital opportunities and associated cyber security challenges will expand as billions of “things” and humans are connected. Embraced by both consumers and enterprises alike, the Internet of Things (IoT) is developing at an exponential rate. Yet while the benefits of our ever more connected society are understood, how to securely manage the influx of new devices onto the network is less clear. For the IoT to flourish, the industry needs an aligned and consistent approach to IoT security. 

An IoT Botnet

Security as a service is emerging as a key trend. In this complex environment, as we move to 5G, everything changes. The networks will become more distributed, and many critical applications will be hosted at the edge of 5G networks and across edge clouds. Critical applications like remote healthcare, remote monitoring and control over our power grids, and self-driving cars will all rely on 5G technologies. Opportunities for threat actors will emerge if they are allowed to go unchecked, as they will use automation to wage multi-stage attacks and find the least secure portions of the 5G networks to exploit.

Issues Cited Regarding Implementing Signalling Controls

Statistics indicate there could be as many as 3.5 million unfilled cyber security jobs by 2021 (Cyber Security Ventures, 2017). The cybersecurity workforce shortage has left CISOs and corporate IT security teams scrambling for talent while the cyberattacks are intensifying. Corporations are responding by placing some or all of their IT security into the hands of third parties. Last year, Microsoft estimated that 75% of infrastructure will be under third-party control by 2020.
