DMZ

What Is DMZ?

DMZ stands for "Demilitarized Zone" and is a type of network security architecture. It is a physical or logical subnetwork that contains and exposes an organization's external-facing services to an untrusted, usually larger, network such as the Internet. The purpose of a DMZ is to add an additional layer of security to an organization's local area network (LAN) by isolating it from the Internet and untrusted networks. This way, any malicious traffic that is directed at the organization's internal network can be blocked at the DMZ, preventing it from reaching the LAN. Additionally, the DMZ can be used to host public-facing services such as web servers, mail servers, and other services that need to be accessible from the Internet.

Description

A DMZ is a network security architecture that creates a separate, isolated network segment between an organization's internal network and the Internet. It is used to protect an organization's internal network from malicious traffic and to host public-facing services.

Usage and Examples

DMZs are commonly used by organizations to protect their internal networks from malicious traffic. For example, an organization may set up a DMZ to block any malicious traffic that is directed at its internal network. Additionally, the DMZ can be used to host public-facing services such as web servers, mail servers, and other services that need to be accessible from the Internet. For example, an organization may set up a web server in its DMZ to serve web pages to visitors from the Internet.
