Firewall

A form of web security that stands between a private network and the Internet to prevent unwanted traffic from passing either way. Some firewalls have proxy functions built in. Often the distinction between a firewall and a proxy is blurry. True firewalls generally support packet-filtering, proprietary application filtering, and some proxy functions.
