A Demilitarized Zone (DMZ) is a network attached to an internetworking device on
the border of a "trusted" and "untrusted" zones. This network typically comprises
the servers and related network resources that need exposure to the "untrusted"
zone without compromising security of a "trusted" zone.
A DMZ creates a buffer space between the Internet and the private network which
is accessed by both Internet and the internal network. A DMZ typically contains
the following:
•
Web Server
•
Mail Server
•
Application Gateway
•
E-Commerce Systems
Example of systems to place on a DMZ include Web servers and FTP servers.
