• A perimeter network is a small network that is set up separately from a company’s
private local area network and the Internet
• It is called a perimeter network because it is usually on the edge of a LAN, but DMZ
is an industry standard term
• A perimeter network allows users outside a company LAN to access specific
services located on the DMZ
• When the perimeter network is set up properly, those users are blocked from
gaining access to the company LAN
• The perimeter network might house a switch with servers connected to it that offer
web, email, and other services
