A VPN is a secure, private communication tunnel between two or more devices across a public network (like the Internet). These VPN devices can be either a computer running VPN software or a special device like a VPN enabled router. It allows your home computer to be connected to your office network or can allow two home computers in different locations to connect to each over the Internet. Even though a VPN?s data travels across a public network like the Internet, it is secure because of very strong encryption. If anyone ?listens? to the VPN communications, they will not understand it because all the data is encrypted. In addition, VPN?s monitor their traffic in very sophisticated ways that ensure packets never get altered while traveling across the public network. Encryption and data verification is very CPU intensive.

Short for irtual rivate etwork, network that is constructed by using public wires to connect nodes. For example, there are a number of systems that enable you to create networks using the Internet as the medium for transporting data. These systems use encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted. VoIP - Voice over Internet Protocol (also called VoIP, IP Telephony, Internet telephony, and Digital Phone) is the routing of voice conversations over the Internet or any other IP-based network. The voice data flows over a general-purpose packet-switched network, instead of traditional dedicated, circuit-switched voice transmission lines.

This creates a secure “tunnel” between the points within the VPN. Only devices with the correct "key" will be able to work within the VPN. The VPN network can be within a company LAN (Local Area Network), but different sites can also be connected over the Internet in a secure way. One common use for VPN is for connecting a remote computer to the corporate network, via e.g. a direct phone line or via the Internet.

(Virtual Private Network) -- Provides a mechanism for forwarding dial-up data packets over the Internet in such a way that end users appear as if connected directly to their destination or home network. This is done using a technique called tunneling. Tunnels represent virtual, dedicated connections between the dial-up access point and a destination point somewhere on the network. The destination is usually the point at which a corporation or an enterprise is connected to the Internet.

Virtual Private Network. VPNs are private networks that are created over a public network (such as the Internet). VPNs often employ a tunneling or encryption software that is installed on the client and recognized by the private network. This software provides user authentication and data integrity for use over the public network.

Virtual Private Network. A VPN is a link through which two sites can communicate privately over a network; no one outside the VPN can intercept their data or add their own data to the connection. VPNs can run on public telecommunications infrastructure, maintaining privacy through the use of a tunneling protocol and security procedures. A VPN gives a company the same connectivity and security they would experience if they installed their own dedicated connections – but VPNs generally are cheaper because they can use shared public infrastructure (Alberta SuperNet, for example).

Virtual Private Network. A company rents or acquires some part of someone else's network (phone company, Internet provider) and makes their own network out of it. They might use a combination of software, dialing codes and some equipment. Businesses can use a virtual private network to do only voice, to do only data, to do just video or to do a combination. It exhibits some characteristics of a private network, even though it uses the resources of a public switched network.

Virtual Private Network. A private network that is configured within a public network (a carrier's network or the Internet) in order to take advantage of the economies of scale and management facilities of large networks. VPNs are widely used by enterprises to create wide area networks (WANs) that span large geographic areas, to provide site-to-site connections to branch offices and to allow mobile users to dial up their company LANs. For years, common carriers have built VPNs that appear as a private national or international network to each customer, but, in fact, are sharing the same physical backbone trunks with many customers. VPNs have been built over X.25, Switched 56, frame relay and ATM technologies as well as IP networks. For added security, encryption is often used. Encrypted connections over the Internet are also very popular for linking remote offices and mobile users; however, for top secret communications, the maximum security is still only afforded by networks of totally private lines.

Virtual Private Network. A term used to describe connecting to a network (such as your office) securely over the Internet.

A software-defined network offered by telephone carriers for voice and data communications among multiple sites. The VPN provides the appearance of a private line network, except that it makes use of the public switched network rather than physically dedicated leased lines. In customer-based VPNs, carriers install gateways, routers, and other VPN equipment on the customer premises. This is preferred when customers want to have control over all aspects of security. In network-based VPNs, the carrier houses all the necessary equipment at a point-of-presence (POP) near the customer's location. Customers that want to take advantage of the carrier's VPN economies of scale prefer this type of VPN.

(n.) virtual private network.

This acronym means "Virtual Private Networking". VPN is a secure means of moving sensitive information across an inherently unsecure network, such as the Internet, to a protected network behind a secure gateway. VPN traffic is encrypted to secure the information, and encapsulated so that the secure gateway understands where to send the traffic in the protected network. Encapsulation can also have the desirable side-effect of concealing the final destination, or the real source from prying eyes during its transmission across the unsecure network. The Raptor Firewall supports the ISAKMP dynamic key exchange mechanism, which reduces the administrative tasks necessary for configuring VPN traffic. Since the IPSEC and ISAKMP technologies are public domain standards, the VPN functionality of the Raptor firewall can interoperate with other vendor platforms that are also compliant.

Virtual Private Network: Enables IP traffic to travel securely over a public TCP/IP network by encrypting all traffic from one network to another Network while using own addresses, management and accounting.
