3.4.3.3 DMZ Settings
In computer security, a DMZ or Demilitarized Zone (sometimes referred to as a perimeter network) is a
physical or logical network that contains and exposes an organization's external-facing services to a
larger and insecure 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.
