Attacks on critical national infrastructure are growing in number and sophistication. So how big is the UK’s risk?
However, at the same time, Jason Hart, CTO of data protection at Gemalto points out that power stations and other industrial SCADA systems connected to the internet have a manual override switch.

If the availability of the system is targeted, it can manually override this so the underlying critical system will have the ability to shut down if needed.”
