Q Thank you, Mr Stringer, and thank you to all the witnesses who have come here today.

John, you rather touched on the challenge: this is an area that is very dynamic. All of us are learning what the security risks are, and in Government—which often moves very slowly—it is a particular challenge to manage such a dynamic, changing picture. That is why in this legislation, we have set out some broad principles and basic requirements, but a lot of this has to be secondary legislation so we can keep up to speed with all the changes that are going to be happening to connected devices, and some of the risks that will come with that. I think it would be very helpful if you could set out for the benefit of the Committee how this picture has changed over the past few years, where you think things will be moving, the extent to which connected devices will be in our homes in future, and some of the security risks that will present.
