In computer networks, a DMZ (De-Militarized 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 company network. 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 initializes
sessions for these requests on the public networks. 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. If an outside user penetrated the DMZ host’s security, only the
Web pages will be corrupted but other company information would not be exposed.
The service provider must provide the exact settings for this mode.
