Ex-GCHQ chief: No company should be offline for weeks after cyberattackRobert Hannigan said no company hit by a cyberattack should be offline for two weeks (Photo by Ben Birchall/AFP via Getty Images)No vigilant company should need to go offline for more than a few days after a cyberattack, the former director of GCHQ has said in comments that will pile fresh scrutiny on Jaguar Land Rover’s (JLR) preparedness before its hack left production at a standstill for over a month.
“It is perfectly possible to build the right prevention defences and then build the right resilience,” he said.
