Devices on 5G networks demand differentiated security solutions

March 05, 2020 / Helpnetsecurity

There will be 8.3 billion mobile broadband subscriptions by the end of 2024, which translates to 95 percent of all subscriptions by then, according to the SMU Office of Research & Tech Transfer. Total mobile data traffic will reach 131 exabytes per month (1 exabyte = 1 billion gigabytes), with 35 percent carried by 5G networks. While mobile phones will consume the bulk of the data, the sheer number and wide variety of devices that will be connected via 5G technology is likely to pose security threats not faced by previous generations of mobile networks, explains Professor Robert Deng at the SMU School of Information Systems. “When 5G becomes pervasive, the majority of the devices connected to mobile networks will not be mobile devices anymore,” he says, referring to things such as household appliances, lightbulbs, or indeed something mobile like an autonomous car that is itself filled with smaller IoT devices such as sensors.
