We’ve already witnessed a massive evolution with mobile networks across the globe as 4G-LTE continues to expand. Mobile network operators, or MNOs, are now evolving these networks rapidly with an eye toward reaching 5G, but there remains a large gap in their security architectures that only widens as they add more bandwidth, lower network latency, and expand overall network capacity to accommodate the exponential growth in device connections and digital application usage that 5G will bring.
This is a perfect storm for cybercriminals, especially as more mobile subscribers with advanced devices are added, along with massive numbers of connected “things” that are projected to attach to mobile networks in the billions of numbers worldwide. Traffic growth between interconnected roaming LTE networks is also accelerating, giving cybercriminals yet another expanding threat vector they can exploit – the roaming interfaces between these networks. Within EU countries, for example, there was approximately 800 percent growth in roaming traffic in 2017. All these factors are increasing business risk over time for mobile operators, and the internet of things, or IoT, is especially a game changer.
A continued reliance on legacy security approaches leaves networks blind and unable to effectively see and stop the accelerating numbers of security threats that will only expand and continue to increase. To close the gap between the 4G/5G networks and security architectures and stay ahead of today’s and tomorrow’s advanced cyberthreats, mobile operators need to adopt new tools and technologies that allow them to:
See deep inside their network traffic – both data and signaling.
Apply big data analytics with automation of security at scale.
Establish an adaptive security architecture that allows for rapid security innovations over time.
