Prime Minster David Cameron has confirmed a budget of £500m for the UK's national cyber security programme in the Strategic Defence Review.
He told MPs the review was not simply a cost-cutting exercise, and represented a review of all elements of security with a new focus on unconventional threats.

Cameron described the investment in cyber defences as a long-term decision aimed detecting and defending against cyber threats and addressing shortfalls in critical networks.
The IT security industry welcomed the government's recognition of the importance of cybersecurity, but expressed the hope this would be followed up with details on funding.
Many in the IT security industry share the view of Ed Miliband, leader of the opposition, that the review is only a partial response to the National Security Strategy.
