The information revolution has had a dramatic impact on every aspect of our lives. Commercial activities, all the way from the world's financial markets to the most basic purchases in stores, are driven by the changes in information technology. It is, therefore, not surprising that military operations are equally bound by these technologies which, at first glance, seem so remote from the world of troop movements and combat. But, in fact, these technologies are changing not only society but also our definition of war and the conduct of military operations. Throughout history, military doctrine, organization and strategy have continually undergone profound, technology-driven changes. Modern warfare, unlike that of past epochs, is "information intensive," meaning the conduct of effective military operations requires a greater accumulation of data than ever before. Today, access to information is just as crucial as possession of petroleum, oil, lubricants, and ammunition. Cyberwar refers to conducting military operations according to information-related principles. It means disrupting or destroying information and communications systems. It means trying to know everything about an adversary while keeping the adversary from knowing much about oneself.
