In case you have no clue what the abbreviations mean:
Code:
DMZ or Demilitarized Zone (sometimes referred to as a perimeter network) is a
physical or logical subnetwork that contains and exposes an organization's
external-facing services to a larger and untrusted network, usually the
Internet. The purpose of a DMZ is to add an additional layer of security to an
organization's local area network (LAN); an external attacker only has direct
access to equipment in the DMZ, rather than any other part of the network.
The name is derived from the term "demilitarized zone", an area between nation
states in which military operation is not permitted. (Source Wikipedia)
