DeMilitarized Zone - known as a DMZ, allows an internal device, such as a client computer, to be seen on
the Internet. Basically, information from the WAN (outside) is sent to a server with a
fi rewall, which evaluates
the information. If the information is valid, it is then sent to another server with another fi rewall for further
evaluation. Although, these two servers are physically within a LAN, they are actually programmed to exist in
front of the LAN to ensure no unwanted packets are transmitted into the LAN.
Notes:
Placing a server or gateway in the “DMZ” may open the system or network to malicious attacks
However, the most common use for the “DMZ” is to systemically place a server or gateway directly onto the
Internet without requiring a class “A or B” address.
