DMZ Configuration
Servers in a network most vulnerable to attack are those which provide services to users outside the local
network. Many times these computers are placed into their own sub-network to provide more protection to
the rest of the local network. This sub-network is called a DMZ (taken from “demilitarized zone”).
Computers in the DMZ have limited connectivity to specific hosts in the internal network, although
communication with other hosts in the DMZ and to the external network is allowed. This allows hosts in the
DMZ to provide services to both the internal and external network, while a firewall controls the traffic
between the DMZ servers and the internal network clients.
The following chart describes the network access control of DMZ
