screened host firewall A FIREWALL which is implemented using a FIREWALL ROUTER and a PROXY SERVER, with the router acting as a front end to the server. The firewall router first screens off any accesses which are disallowed to a closed network, apart from WEB PAGE accesses and secure accesses to services such as EMAIL. The Web accesses are then passed to the proxy server which acts as a front end to the Web server that actually dispenses the Web pages. There are thus two layers of security that a CRACKER has to circumnavigate before accessing the Web server inside the closed network.
