This research paper develops the foundation for a new military operating concept to "fight the net" in support of 8th Air Force requirements and stand-up as the new Cyber Command. It applies the Air Force Concept Development framework to examine cyberspace as a newly designated warfare domain, and proposes cyber capabilities and effects that the Air Force should develop and apply as it seeks to execute its mission in cyberspace. Before the Air Force can effectively lead in the cyber domain, it must first fully characterize cyber conditions, threats, and vulnerabilities, and clearly define how and where it can contribute to the national cyberspace strategy. Once the Air Force accomplishes these tasks, it can then focus on the nature of war in the cyber domain and consider the implications for military doctrine and operations. In order to successfully build capability and capacity for operating in cyberspace, the Air Force needs to institutionalize "cyber-mindedness" to underpin organizational, research and development, and human capital investments that the Air Force needs "to fly and fight" effectively in cyberspace.THE CYBER DILEMMA * Bounding the Cyberspace Domain * Requirement for a New Framework * Physical Attributes * Domain Differentiation: Cyber versus Information Operations in Cyberspace * Broad Implications for Joint Military Operating Concepts * Effects in Cyberspace * Implications for Command and Control, Network Operations, and ISR * A New Military Problem and New Solutions * Missions that Assure Operations in Cyberspace * Time Horizon, Assumptions, and Risks * Relevance and Concluding Thoughts * THE U.S. CYBER SITUATION - THE PERFECT STORM? * Current Conditions in the Cyber Domain * Information Infrastructure and Critical Infrastructure * Existing "Weather Fronts" - Cyber Threat Agents * Threat and Threat Agent Defined * Threat Agent Profiles * Strong Tropical Disturbance Feeding Energy to the Weather Fronts a.k.a.
