Broadband network communications such as cable and DSL provide the bandwidth necessary for effective network remote access over the Internet. Remote access over public networks should be protected from eavesdropping by employing the encryption technology used in VPN (Virtual Private Network) connections that effectively scrambles information so that it is unreadable. Configure Windows computers to accept and initiate VPN connections over a broadband connection using VPN services included with the Windows operating system.
