NATO Secretary General Jens Stoltenberg said a cyber strike on any NATO nation could trigger a revenge attack from all its allies.
In an article for Prospect magazine, he wrote: "We have designated cyberspace a domain in which NATO will operate and defend itself as effectively as it does in the air, on land, and at sea. This means we will deter and defend against any aggression towards allies, whether it takes place in the physical world or the virtual one."
Stoltenberg said the alliance was establishing a new Cyberspace Operations Centre in Belgium, and could also now "also draw from allies’ national cyber capabilities for Nato missions and operations," the Telegraph reported.
The Nato chief said collaboration was vital, explaining that "no single country alone can secure cyberspace", adding: "But by cooperating closely, sharing expertise, we will not only survive, but thrive in the new digital age."
The NATO Secretary General also stressed that cyberspace is the new battleground and making NATO cyber ready, well-resourced, well-trained, and well-equipped-is a top priority as we look towards the NATO summit in London in December and beyond.
