Vpn Security Types

Virtual private networks (VPN) provide an encrypted connection between distributed sites over a public network (e.g., the Internet). By contrast, a private network uses dedicated circuits and possibly encryption. The basic idea is to provide an encrypted IP tunnel through the Internet that permits distributed sites to communicate securely. VPNпїЅs permit secure, encrypted connections between a company's private network and remote users through a third-party service provider. A VPN can grow to accommodate more users and different locations much easier than a leased line. In fact, scalability is a major advantage that VPNпїЅs have over typical leased lines (dedicated circuits). Unlike with leased lines, where the cost increases in proportion to the distances involved, the geographic locations of each office matter little in the creation of a VPN.

Virtual Private Networks allow enterprises to utilize cost effective, secure, and scalable hardware to extend their wide area network. These networks are cost effective in that they are able to connect remote users to the corporate network without the need for expensive dedicate WAN links
