"A primary mission of the Department of Defense (DoD) remains defending the nation in cyberspace, a function which has until this point been oriented around the traditional Defense Support of Civil Authorities (DSCA) Framework. However, conceptual confusion as to the most effective mechanisms for DoD support during national cyber emergencies has generated a perpetual 'fog' that restricts its optimal employment. This paper examines the typical forms of DoD cyber support currently employed, and presents four additional pillars for consideration. These proposed pillars highlight the potential value of DoD's defined role and functionality as a supporting command to the private sector during national cyber emergencies. Furthermore, this paper recommends new adaptable structures and defined roles that can serve as a model for DoD's future composition, disposition, and employment in cyberspace when called upon to defend the nation. Because the private sector is on the front lines of the conflict, a new model of Defense Support to the Private Sector (DSPS) needs consideration."
