VPN (Virtual Private Network) |
|
|
|
A private
encrypted tunnel through a public
network like the internet that provides an additional layer of security.
VPN's rely on having the
same encryption
hardware or software at both ends.
Link-level (layer 2 and 3) encryption prevents traffic analysis (a form of
attack), and provides extra protection by encrypting each datagram except the link-level information. This prevents a listener from obtaining information about
your network structure. |
