For example, the sample diagram does not indicate the physical type of connection between the PCs and the switch, but since a modern LAN is depicted, Ethernet may be assumed. If the same style of line was used in a WAN (wide area network) diagram, however, it may indicate a different type of connection.

Diagram of a typical network employing DMZ using dual firewalls. The most secure approach, according to Colton Fralick, [4] is to use two firewalls to create a DMZ. The first firewall (also called the "front-end" or "perimeter" [5] firewall) must be configured to allow traffic destined to the DMZ only. The second firewall (also called "back-end ...
Diagram of a conventional DMZ that would be used by a business. All traffic to the DMZ must pass through a firewall, which limits throughput. A firewall must restrict access to the internal network but allow external access to services offered to the public, such as web servers on the internal network.
The equipment that ties together the departmental networks constitutes the network backbone. Another example of a backbone network is the Internet backbone, which is a massive, global system of fiber-optic cable and optical networking that carry the bulk of data between wide area networks (WANs), metro, regional, national and transoceanic networks.
In network security a screened subnet refers to the use of one or more logical screening routers as a firewall to define three separate subnets: an external router (sometimes called an access router), that separates the external network from a perimeter network, and an internal router (sometimes called a choke router) that separates the ...
