We are under cyber siege. The number of “highly significant” cyber-attacks – those affecting government, essential services and key sectors of the economy surged by half over the past year, the National Cyber Security Centre (NCSC) revealed in its annual review this week. While large-scale cyber attacks attract news and media coverage, the everyday technology we increasingly take for granted such as mobile phones, cars, air traffic control, home internet routers and electronic lighting are also increasingly vulnerable.This technology is rarely spoken about as a risk because it is dispersed throughout society, not centralised into one company or organisation.China’s grip on the communications technology market is tightening. Chinese companies, including Huawei and Hikvision, have long been accused of producing technology that poses national security risks. What is your take on the cyber threats ?
