DoDD 8500.01E

DMZ (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 network from outside attacks. A DMZ is also called a "screened subnet." E2.1.15.

DoDI 8500.02

DMZ (Demilitarized Zone)- Perimeter network that adds an extra layer of protection between internal and external networks by enforcing the internal network's IA policy for external information exchange. A DMZ, also called a "screened subnet," provides external, untrusted sources with restricted access to releasable information while shielding the internal networks from outside attacks ( reference (a)). E2.1.16.

DMZ - SEE Demilitarized Zone.

NIST SP 800-41

DMZ - Demilitarized Zone, a network created by connecting two firewalls. Systems that are externally accessible but need some protections are usually located on DMZ networks.
