E2.1.6. DoD Information Technology Standards Registry (DISR). The DISR
provides the minimal set of rules governing the arrangement, interaction, and
interdependence of system parts or elements, whose purpose is to ensure that a
conformant system satisfies a specified set of requirements. It defines the service areas, interfaces, standards (DISR elements), and standards profiles applicable to all DoD systems. Use of the DISR is mandated for the development and acquisition of new or modified fielded IT and NSS systems throughout the Department of Defense. The DISR replaced the Joint Technical Architecture.
