  "definition": "1. Specific to EPA, the Intranet consist of those servers that are available only to EPA and those designated outside \"epa.gov\" who have access. Because new equipment will have new names, we refer to \"Intranet\" and it's counterpart \"Public Access\" to represent the two realms of EPA information that is served in a Web environment. Below is a general description of an Intranet.\n\n2. An intranet is a network of networks that is contained within an enterprise. It may consist of many interlinked local area networks and also use leased lines in the wide area network. Typically, an intranet includes connections through one or more gateway computers to the outside Internet. The main purpose of an intranet is to share company information and computing resources among employees. An intranet can also be used to facilitate working in groups and for teleconferences. An intranet uses TCP/IP, HTTP, and other Internet protocols and in general looks like a private version of the Internet. With tunneling, companies can send private messages through the public network, using the public network with special encryption/decryption and other security safeguards to connect one part of their intranet to another. Typically, larger enterprises allow users within their intranet to access the public Internet through firewall servers that have the ability to screen messages in both directions so that company security is maintained. When part of an intranet is made accessible to customers, partners, suppliers, or others outside the company, that part is called an extranet.\n\n3.
