As information and communication technology (ICT) has extended into all areas of society, we have become ever more reliant upon it. The subtle ways in which it is changing the world, though both exciting and frightening, are not widely recognized or understood. This year, Japan will host the G-7 summit in the Ise-Shima region, and in four years the 2020 Tokyo Olympic and Paralympic Games. As these large-scale, global events have now become completely dependent on ICT, the threat landscape has also evolved. There is greater concern about a hybrid threat that would use computers as cyberweapons to carry out attacks on physical infrastructure. Data breaches worldwide are now so common that we hardly pay attention to the news. Even the recent theft of personal information records from the Japan Pension Service had little lasting impact. Yet the frequency and severity of such attacks is certain to increase. The ease and borderless nature of this threat ensures that no one is immune from such attacks, yet individuals and corporations are complacent about both the threats and the risks.
