Richard A. Clarke warned America once before about the havoc terrorism would wreak on our national security-and he was right. Now he warns us of another threat, silent but equally dangerous. Cyber War is a powerful book about technology, government, and military strategy; about criminals, spies, soldiers, and hackers. It explains clearly and convincingly what cyber war is, how cyber weapons work, and how vulnerable we are as a nation and as individuals to the vast and looming web of cyber criminals. This is the first book about the war of the future-cyber war-and a convincing argument that we may already be in peril of losing it.
