CNSSI 4009

Demilitarized Zone - Perimeter network segment that is logically between internal and external networks. Its purpose is to enforce the internal network's IA policy for external information exchange and to provide external, untrusted sources with restricted access to releasable information while shielding the internal networks from outside attacks. A DMZ is also called a "screened subnet."
