"America's growing dependence on cyberspace has created new vulnerabilities that are being exploited as fast as or faster than the nation can respond. Cyber attacks can cause economic damage, physical destruction, and even the loss of human life. They constitute a serious challenge to U.S. national security and demand greater attention from American leaders. Despite productive efforts by the U.S. government and the private sector to strengthen cyber security, the increasing sophistication of cyber threats continues to outpace progress. To help U.S. policymakers address the growing danger of cyber insecurity, this two-volume report features accessible and insightful chapters on cyber security strategy, policy, and technology by some of the world's leading experts on international relations, national security, and information technology."--Publisher's website
