Interestingly the first war game will involve the Bank of England and commercial banks, targeting the City of London and Wall Street, and will be followed by "further exercises to test critical national infrastructure", according to Downing Street.
In terms of the planned cyber war games Downing Street said they will aim to improve the flow of information between the US and UK about threats. No 10 said agents will co-operate in "cyber cells", involving MI5 and the FBI, and they will be the first the UK has established with another country. Speaking to BBC political editor Nick Robinson after arriving in Washington on Thursday night for a two-day visit, Mr Cameron said cyber attacks were "one of the big modern threats that we face".
