The next generation of cellular technology is expected to revolutionise the way we communicate, with its increased bandwidth and lower latency expected to facilitate emerging technologies such as autonomous vehicles. "5G is really the first time that you're going to see the next industrial revolution that results directly from a new communications infrastructure," said Ferguson, speaking at Cyber Security Nordic, an information security conference in Helsinki, Finland. But for all the benefits it has been touted to bring, the proliferation of connected devices will cause headaches among security professionals in the "not too distant future", he warned. While autonomous digital weapons and deepfakes are "emotionally frightening", these problems are much further down the line and will be at a much smaller scale compared to the threats that will arise in a hyperconnected 5G world, he said. Previous generations of cellular technology have created fresh cybersecurity challenges.
