The DMZ is short for "demilitarized zone." It is in order to solve the external network can not access to the internal network server install the firewall problem, and set up a security system and security system between the buffer, the buffer between internal network and external network small network area, in this area can put some small network must open server facilities, such as enterprise Web server, FTP server, BBS and so on. On the other hand, through such a DMZ zone, the internal network is more effectively protected, because this network deployment, compared with the usual firewall scheme, for attackers to another hurdle.

Network equipment developers, using this technology, developed the corresponding firewall solution. It is called "demilitarized zone structural model". A DMZ is usually a filtered subnet that creates a security zone between the internal and external networks. The DMZ firewall scheme adds a security line to the internal network to be protected and is generally considered very secure. At the same time, it provides an area to put the public server, so as to effectively avoid the situation that some interconnected applications need to be exposed, which is inconsistent with the internal security policy. The DMZ zone typically includes the fortress host, Modem pool, and all public servers, but note that the e-business server can only be used as a user connection, and true e-business backend data needs to be placed on the internal network.
