But the spread of digital technology comes at a cost: it exposes armies and societies to digital attack.
The threat is complex, multifaceted and potentially very dangerous. Modern societies are ever more reliant on computer systems linked to the internet, giving enemies more avenues of attack. If power stations, refineries, banks and air-traffic-control systems were brought down, people would lose their lives. Yet there are few, if any, rules in cyberspace of the kind that govern behaviour, even warfare, in other domains. As with nuclear- and conventional-arms control, big countries should start talking about how to reduce the threat from cyberwar, the aim being to restrict attacks before it is too late.
The army reboots
Cyberspace has become the fifth domain of warfare, after land, sea, air and space. Some scenarios imagine the almost instantaneous failure of the systems that keep the modern world turning. As computer networks collapse, factories and chemical plants explode, satellites spin out of control and the financial and power grids fail.
