DMZ
Stands for "Demilitarized Zone." In computing, a
DMZ is a section of a network
that exists between the intranet
and a public network, such as the Internet. It may contain a
single host
or multiple computer systems.
The purpose of a DMZ is to protect an intranet from external
access. By separating the intranet from hosts that can be accessed outside a
local network (LAN),
internal systems are protected from unauthorized access outside the network.
For example, a business may have an intranet comprised of employee workstations. The
company's public servers,
such as the web server
and mail server could be placed in a DMZ so they are separate from the
workstations. If the servers were compromised by an external attack, the
internal systems would be unaffected.
A DMZ can be configured several different ways, but two of
the most common include single firewall and dual firewall
architectures. In a single firewall setup, the intranet and DMZ are on separate
networks, but share the same firewall, which monitors and filters traffic from
the ISP. In a dual firewall
setup, one firewall is placed between the intranet and the DMZ and another
firewall is placed between the DMZ and the Internet connection. This setup is
more secure since it provides two layers of defense against external attacks.
NOTE:
The term "DMZ" or "Demilitarized Zone" comes from a
military term used to describe a neutral area where military operations are not
allowed to take place. These areas typically exist along the border between two
different countries. They serve as a buffer and are designed to prevent
unnecessary escalations of military action. Similarly, a DMZ is a neutral area
within a computer network that can be accessed by both internal and external
computer systems.
