What is VPN and How do I get It?

On my Ipod touch, there is two things: Wifi Network (I know what this is) and then VPN, what is VPN? Is it free? How do I get it? And how do I set it up, I am very confused.|||VPN stands for Virtual Private Network





You say "Gee Thanks - now what does that mean?"





Here's and example





You work at Widgets Inc. and have access to the office network when you are at work.


You want to be able to access your office network from a remote location (your home - your really dedicated) over the Internet.


However, Widgets Inc, has some secrets they want to keep secret, so they want a secure way for you to connect. Leaving an open hole in their corporate firewall for your use is just too easy to hack.





Enter the VPN


Through some IT magic we will not go into, the IT group uses the router at the office and the router at you remote location (your home) to create an encrypted, secured connection between the two routers. The connection is for these two routers only, no other connections are accepted. The data passed back and forth is encrypted, so even if the packets were intercepted, they would not make any sense.


As far as you are concerned, you are at your house, and connected to the office network just as is you were at your desk.





The chances are you do not need a VPN.for your IPOD





Have a good one|||It stands for Virtual Private Network and you need Software to do it and truthfully you don't need it. This is for high profile Corperate Networks that are anal about security.
