berhubung sama kondisinya,
cuma bisa ngasih kutipan dari http://whatis.com/dmz.htm
DMZ (demilitarized zone)
In computer networks, a DMZ (demilitarized zone) is a computer host or small
network inserted as a "neutral zone" between a company's private network and
the outside public network. It prevents outside users from getting direct
access to a server that has company data. (The term comes from the
geographic buffer zone that was set up between North Korea and South Korea
following the war in the early 1950s.) A DMZ is an optional and more secure
approach to a firewall and effectively acts as a proxy server as well.
In a typical DMZ configuration for a small company, a separate computer (or
host in network terms) receives requests from users within the private
network for access to Web sites or other companies accessible on the public
network. The DMZ host then initiates sessions for these requests on the
public network. However, the DMZ host is not able to initiate a session back
into the private network. It can only forward packets that have already been
requested.
Users of the public network outside the company can access only the DMZ
host. The DMZ may typically also have the company's Web pages so these could
be served to the outside world. However, the DMZ provides access to no other
company data. In the event that an outside user penetrated the DMZ host's
security, the Web pages might be corrupted but no other company information
would be exposed. Cisco, the leading maker of routers, is one company that
sells products designed for setting up a DMZ.
