<p> 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. <i>Cyber War</i> is a powerful book about technology, government, and military strategy; about criminals, spies, soldiers, and hackers. 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. </p> <p> <i>Cyber War</i> goes behind the "geek talk" of hackers and computer scientists to explain 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. From the first cyber crisis meeting in the White House a decade ago to the boardrooms of Silicon Valley and the electrical tunnels under Manhattan, Clarke and coauthor Robert K. Knake trace the rise of the cyber age and profile the unlikely characters and places at the epicenter of the battlefield. They recount the foreign cyber spies who hacked into the office of the Secretary of Defense, the control systems for U.S. electric power grids, and the plans to protect America's latest fighter aircraft. </p> <p> Economically and militarily, Clarke and Knake argue, what we've already lost in the new millennium's cyber battles is tantamount to the Soviet and Chinese theft of our nuclear bomb secrets in the 1940s and 1950s. The possibilities of what we stand to lose in an all-out cyber war -- our individual and national security among them -- are just as chilling. Powerful and convincing, <i>Cyber War</i> begins the critical debate about the next great threat to national security. </p>
