VPN
Virtual Private Network, a private network constructed across a public network such as the Internet.
A VPN can be made secure, even though the network uses using existing Internet connections to
carry data communication. Security measures involve encrypting data before sending data across
the Internet and decrypting the data at the other end. To add an additional level of security, you can
encrypt the originating and receiving network address.
