This week, U.S. soldier Travis King crossed the Demilitarized Zone, or DMZ, which separates South Korea and North Korea. He is believed to be in the custody of North Korean forces.
The direct data exchange between LAN and DMZ is not possible via the LAN bridge if a dedicated DMZ port is used. The path from the LAN to the DMZ and vice versa is therefore only through the router, and thus through the firewall. This in turn shields the LAN against requests from the...
It is ideally located between two firewalls, and the DMZ firewall setup ensures incoming network packets are observed by a firewall—or other security tools—before they make it through to the servers hosted in the DMZ. This means that even if a sophisticated attacker is able to get past th...
This is to separate them from the internal network. This way, should these servers become compromised, the attack is unlikely to cause damage, loss, or exposure. Servers in the DMZ are accessible from the Internet, but the rest of the internal LAN remains unreachable. Therefore, it becomes...
In creating a DMZ, an organization inserts another network segment or subnet that is an element of the system, but not connected directly to the network. It can be inserting a DMZ creates use of a third interface port on the firewall. This configuration enables the firewall to transfer data...
What is a Demilitarized Zone (DMZ)? A demilitarized zone (DMZ) is an IT security framework for protecting trustedlocal-area networks(LAN) by passing all untrusted external traffic through an intermediate proxy network. DMZ networks are also known asperimeter networks. They sit between a physical ...
A DMZ network, in computing terms, is a subnetwork that shears public-facing services from private versions. When implemented correctly, a DMZ network should reduce the risk of acatastrophic data breach. Public-facing servers sit within the DMZ, but they communicate with databases protected by fir...

It is in these situations that a DMZ host can be setup. Any device that is configured as a DMZ host on a router is excluded from the firewall protections that the router offers. This means that all ports on the device are externally accessible, which is good for the purposes of ...
Alternatively known as a DMZ host, DMZ is short for DeMilitarized Zone and is a buffer area between outside users (the Internet) and a private (local) server. DMZs are used by corporations and contain a device that accepts Internet traffic such as DNS (Domain Name System), FTP (File Tra...
