Advanced Deployment Options

3-13

Because a DMZ is a network area (a subnetwork) that sits between an organization's

internal network and an external network, two appliances are necessary to protect

both areas.

See figure 3-9 for an illustration of a deployment with two appliances deployed as

mentioned above. In the illustration, the company LAN is the area with a gray border

and the DMZ is the area with a red border.
