“To get a feel for how the North’s military has gone about organizing for cyber activities, the best unclassified source I know of remains Christopher Brown’s 2004 Naval Postgraduate School thesis “Developing a Reliable Methodology for Assessing the Computer Network Operations Threat of North Korea.” Brown wrote, by the way, that his thesis was an attempt “to prove that a useful methodology for assessing the CNO capabilities and limitations of North Korea can be developed using only open source information” (emphasis added). Brown also wrote about the early personal role of Kim Jong Il’s eldest son Kim Jong Nam in establishing the priority of computer network operations among military activities (Nam once headed a North Korean intelligence agency, though in recent years he dissipated into a South-Park-like role as a casino-loving playboy).”
