The Conservative Party will set up a new cyber threat and assessment centre, review key national databases and critical infrastructure systems, and scrap the national identity card system, says party leader David Cameron.
The party also plans to review the controversial Interception Modernisation Programme, which collects information about every electronic message sent and received or which crosses UK borders.
"We know that there are hundreds of thousands of cyber-attacks and crimes against British businesses every year," Cameron said at the launch of the Conservatives' Green Paper on national security, A Resilient Nation.
He referred to the so-called "Clickskrieg" against Estonia in 2007, which disrupted government, banking and business for several days. "I want Britain to be prepared and proactive and ready to deal with all kinds of cyber attacks," Cameron said.
Cameron said the police DNA database, which contains DNA profiles of one million people who have never been charged or found guilty or a crime, would be run along the lines that apply in Scotland.
Cameron said Britain had not adapted to the demands of the modern world. "We still look at this changed world through the lens of institutions which fundamentally have not changed since the end of the Cold War," he said.
Cameron said he would appoint a national security advisor to lead a streamlined US-style national security council that would coordinate the government's military and civilian security activities, and which would serve as a de facto War Cabinet during the Afghanistan campaign.
The council's first and second tasks respectively would be to draw up a new national security strategy and conduct a strategic defence and security review.
The Conservatives would set up a National Resilience Team reporting to the Cabinet Office that would take an "all hazards" approach to critical infrastructure and emergency response. Elements of the CESG, GCHQ's electronic security group, the Information Security and Assurance Group, the Centre for the Protection of National Infrastructure and others would serve on the team.
