what is VPN ?

Question

Of course I know what VPN (Virtual Private Network) means, but I need some deep, easy and brief helps/guides/papers to have a comprehensive look at the issue. Thanx!

Answer 1

Basically it is a secure connections from one place to another like from your house to your work. A business can setup a large vpn to have everyone communicate and send files to each other securely.

Answer 2

You can connect two computers together and share stuff using the Internet but this is not very secure. What you need is a way of conncting computers together that uses encryption (and a few other security tricks involving packets and ports) yet still uses the Internet. This is a VPN. It is used a lot in industry for remote access to data held in the office. Some broadband routers iclude an option for VPN. Buy two of these give one to a mate connect up and off you go

Answer 3

I´ll try to explain it on a non technical way.
Its a secure way to comunicate you with a parthner establishing a tunnel over the internet where you will have a unique key (shared secret or Certificate) that just only you and the gateway you are trying to reach will know in order to grant you access to some resource on a Lan.
This communication is secure becuase uses some encryption algorithms in order to encrypt the information you're to transmit or receive.
