The extent with which 5G networks use software is one of the top security issues for mobile networks as well as devices and current technologies (for example, 3G, 4G) that use or incorporate it, according to an EU report supported by the European Commission and European Union Agency for Cybersecurity.
5G networks are unique compared to wireless network technologies in that they are mostly software-defined, including their network functions. 5G is also poised to use edge computing, where an application’s processing, storage, and management capabilities are contained near, for example, an internet-of-things (IoT) endpoint. This kind of architecture is among what the European Commission and European Union Agency for Cybersecurity say could broaden attack surfaces that threat actors can then abuse to gain a foothold into their targets.
