Security is a mission critical function of the Department of Defense (DoD), and its proper execution has a direct impact on all DoD missions and capabilities and on the national defense. The Defense Security Enterprise (DSE) consists of senior executives from organizations across the DoD that come together to create policy, oversight framework, and governance structure to safeguard DoD personnel, property, information, operations, and mission against harm, loss, or hostile acts and influences. The DSE is governed by two organizations: the Executive Committee (DSE EXCOM) and the Advisory Group (DSEAG).
