Cyberwarfare, like the seismic shift of policy with nuclear warfare, is modifying warfare into non-war warfare. A few distinctive characteristics of cyberwar emerge. Cyberwarfare has blurred the distinction between adversary and ally. Cyber probes continuously occur between allies and enemies alike, causing cyberespionage to merge with warfare. Espionage, as old as war itself, has technologically merged with acts of cyberwar as states threaten each other with prepositioned malware in each other's cyberespionage probed infrastructure. These two cyber shifts to warfare are agreed upon and followed by the US, Russia and China. What is not agreed upon in this shifting era of warfare are the policies upon which cyberwarfare is based. This book charts the policies in three key actors and navigates the futures of policy on an international stage.
