Military and intelligence leaders agree that the next major war is not likely to be fought on the battleground but in cyber space. Richard Stiennon argues the era of cyber warfare has already begun. Recent cyber attacks on United States government departments and the Pentagon corroborate this claim. China has compromised email servers at the German Chancellery, Whitehall, and the Pentagon. In August 2008, Russia launched a cyber attack against Georgia that was commensurate with their invasion of South Ossetia. This was the first time that modern cyber attacks were used in conjunction with a physical attack. Every day, thousands of attempts are made to hack into America's critical infrastructure. These attacks, if successful, could have devastating consequences. In Surviving Cyberwar, Stiennon introduces cyberwar, outlines an effective defense against cyber threats, and explains how to prepare for future attacks.
