The global reliance on computers, networks and systems continues to grow. As our dependency grows so do the threats that target our military s Command, Control, Communications, Computers, Intelligence, Surveillance, Reconnaissance (C4ISR) systems as well as the operational components and electronic controls for our critical infrastructure. Over the past decade we have experienced a substantial rise in the complexity and sophistication of cyber attacks as well as a frightening increase in the impact of some of the attacks. Every computer is a potential cyber weapon waiting to be loaded and used by extremists, criminals, terrorists and rogue nation states. As the world becomes more and more dependent on computers and information technology, the greater the risk of cyber attacks. Government and military leaders now face this fact and our critical systems and infrastructure remain at great risk! This risk has made the ability to defend these critical systems and direct cyber attacks core capabilities required for the modern military. In the age of cyber conflict, leaders need to understand the weapons and strategies used to wage this rapidly evolving type of warfare. This handbook will provide the background needed to understand the new world of cyber warfare, define the tools and techniques for offensive and defensive action, and provide insight into the strategies behind building a dynamic and relevant cyber warfare capability.
