VPN Tunnel S20
“Virtual Private Network” or VPN is a mechanism to extend a private network across a public network such as the Internet. A VPN creates a point to point connection or “tunnel” across the Internet between two computers. The tunnel encrypts the data between VPN endpoints, preventing data from being deciphered without the required encryption keys.
