What is a DMZ, and why do I want one?

Answer 1

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 UN "police action" 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 router s, is one company that sells products designed for setting up a DMZ.

Answer 2

In computer networks a DMZ is a demilitarized zone. A DMZ acts as a buffer between your computer and the Internet. If you are running a game server or an ftp server you would want a DMZ so outside computers do not have access to your network but do have access to the service you are providing. If you are not running a service open to the public you do not need a DMZ.

Answer 3

From Wikipedia:
"In computer security, a demilitarized zone (DMZ) or perimeter network is a network area (a subnetwork) that sits between an organization's internal network and an external network, usually the Internet. The point of a DMZ is that connections from the internal and the external network to the DMZ are permitted, whereas connections from the DMZ are only permitted to the external network -- hosts in the DMZ may not connect to the internal network."

I hope this helps you out!

The article also says:
"The DMZ is typically used for connecting servers that need to be accessible from the outside world, such as e-mail, web and DNS servers."

Answer 4

DMZ stands for demilitarized zone. It's a part of your computer network that has absolutely no protection against hackers, viri, worms, and other threats. A normal computer user does not want one. An advanced computer user will want a DMZ so his peer to peer file sharing is faster.
