Computer hackers have managed to breach some of the top secret systems within the Ministry of Defence, the military’s head of cyber-security has revealed.
Major General Jonathan Shaw told the Guardian the number of successful attacks was hard to quantify but they had added urgency to efforts to beef up protection around the MoD’s networks.
“The number of serious incidents is quite small, but it is there,” he said. “And those are the ones we know about. The likelihood is there are problems in there we don’t know about.”
