Preparedness in the event of a catastrophic cyber attack

DG made this Rhyddid Gwybodaeth request to Prime Minister's Office

Automatic anti-spam measures are in place for this older request. Please let us know if a further response is expected or if you are having trouble responding.

We're waiting for DG to read a recent response and update the status.

Dear Prime Minister

This is an FOIA request about the Government’s readiness for the consequences of a major cyber attack, but first a couple of comments to put the request into context.

i. A massive cyber attack by an enemy state is a clearly foreseeable event – whether it is Russia, China, Iran or North Korea. They already engage in cyber attacks on a lesser scale but it is not beyond the bounds of possibility that they have the capacity to launch more serious attacks.

ii. The current Covid pandemic was also foreseeable, not only in real life, but also in popular culture, yet large parts of the western world were unprepared for it and we are paying the price for this with deaths that could have been prevented.

iii. On a lesser scale than Covid, but just as tragically, 72 people died in the Grenfell Tower fire, despite advance warnings by tenants of fire risks. These warnings went unheeded by those responsible for the safety of the block.

With this in mind, these are my questions:

1. Does the Government have a plan for coping with the consequences of a major cyber attack?

Please note that I am not asking for details of how you will get IT systems up and running again after cleansing them of viruses and malware etc., I am talking about the aftermath of a truly apocalyptic attack on major infrastructure such as the electricity distribution system, water distribution, the NHS, mobile phone networks and air traffic control systems etc.

2. To put the question more brutally does the Government have a plan to feed people if there is no electricity, no water and no means of communication?

3. If you do not have such a plan please say so.

4. If you do not have such a plan do you intend to create one?

5. If you do not intend to create one please say why not?

6. If you do have a plan is it accessible to the public?

7. If it is not accessible to the public, why not?

During the Cold War there were plans on how to live in a post-nuclear bomb world so I would hope that there are similar plans for a post cyber attack world. It was also the case that bunkers had been prepared for certain key officials to shelter in.

8. Have any bunkers been prepared for the aftermath and have any key Government officials been designated as meriting a place in the bunker? If so, which ones?

I would be grateful if you responded to this request in a spirit of openness and transparency and not to limit your response to what is technically allowed under the FOIA. The request has not been sent for the purpose of exposing deficiencies in the Government’s emergency response capabilities but out of a genuine desire to learn what the position is, and maybe even prompt the Government to examine their readiness and prepare the right response to such a disaster.

Thank you.
