Distributed firewall

<p>A distributed firewall is a security application on a <a href="/facts/Host_(network)/HPNcFXHk">host</a> machine of a network that protects the servers and user machines of its enterprise's networks against unwanted intrusion. A <a href="/facts/Firewall_(computing)/Et2RkJaU">firewall</a> is a system or group of systems (<a href="/facts/Router_(computing)/Nh5cIyVf">router</a>, <a href="/facts/Proxy_server/ArhwQE74">proxy</a>, or <a href="/facts/Gateway_(telecommunications)/YTYSqhqN">gateway</a>) that implements a set of security rules to enforce access control between two <a href="/facts/Computer_network/3w5RM99p">networks</a> to protect the "inside" network from the "outside" network. They filter all traffic regardless of its origin—the Internet or the internal network. Usually deployed behind the traditional firewall, they provide a second layer of defense. The advantages of the distributed firewall allow security rules (<a href="/facts/Security_policy/8yTdF5eL">policies</a>) to be defined and pushed out on an enterprise-wide basis, which is necessary for larger enterprises.
