DMZ
Demilitarized Zone.
In computer security, a Demilitarized Zone (sometimes referred to as a perimeter network) is
a physical or logical sub-network that contains and exposes an organization's external-facing
services to a larger and untrusted network, usually the Internet.
The purpose of a Demilitarized Zone is to add an additional layer of security to an

).
An external attacker only has access to equipment in the Demilitarized Zone, rather than any
other part of the network.
