In Computer Networking, What is DMZ?
A Demilitarized Zone or DMZ is a network segment that is separated from other networks. Many organizations will use a DMZ to separate their Local Area Networks (LANs) from the Internet to put additional security between their corporate network and the public Internet. Common items to be placed in a DMZ are public facing servers. For example, if an organization maintains their website on a server, that web server could be placed in the DMZ. This way if the machine would ever be compromised, the remainder of the company’s network is not in danger. When connecting a LAN to the Internet, a router will provide the physical connection to the public Internet, and a firewall will provide a gateway to prevent malicious data from entering the network. One port on the firewall will connect to the corporate network using an internal address on that network, allowing traffic being sent out by individuals within the company to reach the Internet. Another port will be configured with a public address
