When operating one of the most complex and critical networks on the planet, risk is a given. That risk comes in two forms, technical and operational, and managing both is a matter of balance.
Roger Greenwell, Defense Information Systems Agency (DISA) risk management executive and authorizing official, is responsible for maintaining that balance on the Defense Information Systems Network (DISN), a global enterprise network that enables information superiority and critical communications. The DISN is the core of the Department of Defense Information Network, a worldwide conglomeration of military networks.
