The United States military has taken a number of steps to confront the threat of cyber warfare. These include organizational, operational, and personnel changes by all the armed services, as well as the joint commands, which conduct operational warfare. Many of these changes began before the terrorist attacks of 9/11 as military planners recognized the vulnerabilities the nation faced to asymmetrical warfare conducted in cyberspace, as well as the military’s dependency on key critical infrastructures within the United States that were vulnerable to cyber warfare. Although many changes have taken place, to include training new classes of military officers and enlisted specialists in career fields and military doctrine related to cyber warfare (both offensive and defensive), the military continues to remain vulnerable to an adversary’s ability to control the informational battlefield. Thus, a key strategic goal of the U.S. military leadership is to achieve information superiority over its current and potential adversaries.
