In conjunction with the Department of Energy's (DOE'S) role as part of the U.S.
intelligence community, the Office of Intelligence and Counterintelligence (IN) provides
technical intelligence analyses on all aspects of foreign nuclear weapons, nuclear
materials, and energy issues. IN has played an increasingly significant role in a number
of intelligence related areas, such as counter-proliferation, counterintelligence, cyber
security, and combating nuclear terrorism.
