VPN connections are also being used to connect remote users together. Virtual Private Networks are commonly used by medium to large organizations to connect remote sites together using a public network such as the internet. Note that the term “VPN connection” refers to the portion of the connection where the private data is encrypted, and the term “tunnel” refers to the portion of the connection where the data is encapsulated. When data is encrypted, one or more encryption keys will be required in order to decipher that data and these encryption keys should only be known by the sender and receiver. If an intruder or attacker is able to intercept data packets during their transmission, they will be unable to understand the data content because the data is encrypted. Not only the data is encapsulated, it is also encrypted to preserve its confidentiality. So how does a public network emulate a point-to-point link? When a public network encapsulates data with a header that contains routing information, the data will be able to be transmitted to the desired endpoint through the public network, without reaching another destination. “Virtual private networking” refers to the creation and configuration of a private network connection. Virtual Private Networks allow people to send data between computers connected via a public network that emulates a point-to-point private connection. A virtual private network is a private network which encloses links across shared networks or public networks (such as the internet).
