| dc:description | Systems that act as a gateway between two networks to enforce an access policy. (ISD) |
| dc:description | A system designed to control the passage of information from one network into a second network. Typically a firewall will be used as a means of reducing the risk of unwanted access to sensitive systems, where one carefully regulated network contains the sensitive systems and is connected to a larger less-regulated network.
