Virtual Private Networking
|
|
|
|
|
==========================
|
|
|
|
|
|
|
|
|
|
A virtual private network secures public network connections and in doing so it
|
|
|
|
|
extends the private network into the public network such as internet. With a VPN
|
|
|
|
|
you can create large secure networks that can act as one private network.
