DMZ network
« on: May 29, 2015, 02:13:31 PM »
In computer security, a DMZ or demilitarized zone (sometimes referred to as a perimeter network) is a physical or logical subnetwork that contains and exposes an organization's external-facing services to a larger and untrusted network, usually the Internet. The purpose of a DMZ is to add an additional layer of security to an organization's local area network (LAN); an external network node only has direct access to equipment in the DMZ, rather than any other part of the network. The name is derived from the term "demilitarized zone", an area between nation states in which military operation is not permitted.
In the military sense, a DMZ is not seen as belonging to either party bordering it. This concept applies to the computing use of the metaphor in that a DMZ which is, for example, acting as a gateway to the public Internet, is neither as secure as the internal network, nor as insecure as the public internet.
In this case, the hosts most vulnerable to attack are those that provide services to users outside of the local area network, such as e-mail, Web and Domain Name System (DNS) servers. Because of the increased potential of these hosts suffering an attack, they are placed into this specific subnetwork in order to protect the rest of the network if an intruder were to compromise any of them successfully.

Hi,

Short for demilitarized zone, a computer or small subnetwork that sits between a trusted internal network, such as a corporate private LAN, and an untrusted external network, such as the public Internet.
Typically, the DMZ contains devices accessible to Internet traffic, such as Web (HTTP ) servers, FTP servers, SMTP (e-mail) servers and DNSservers.The term comes from military use, meaning a buffer area between two enemies.

Thanks.
