Re: vpn's
My company uses a VPN for us to access the company computer system remotely from home or while traveling. I have a VPN device that generates a number code that changes every 30 seconds. To log on to my company remotely I have to use special software that has me enter a personal PIN number I came up with and then the number code on my fob that is showing at the time I want to log on. It keeps an unathorized person from accessing my companies computer system should a laptop get stolen.

The way it works is that a router or server on the receiving end is set up to authorize users based upon either a public or private encryption key exchange. Once the remote user is authorized, all of their communications with the "home office" are encrypted and unreadable by anyone who may tap the line or otherwise intercept the communication. Video and voice over IP packets are also encrypted and protected on a VPN. You set up your own using something like Open VPN - you can probably find the latest copy of that at Sourceforge.net. Just install on your server at home, configure your router to allow it and the log on from one of those swanky European hotels or even an Internet cafe in Bangkok. Lower the brim of your fedora and turn up your collar as you use your home web cam to check on your pets or to play Solitaire on another machine at home. The uses are endless... and mostly useless. The United States State Department and the DoD use different implementations of VPN for some of their communications over the Internet. Lots of top secret stuff there, and it's well protected. Reasonably well protected. At least the only major leaks have always come from the inside, like that gerbil who sold us out to Wikileaks for a bowl full of pottage. Loser. Si Si Juan appears to be describing the popular RSA token. It is an additional measure to keep unauthorized users from logging in to a network. |

Re: vpn's
Yes, there are public VPNs (as in, a VPN tunnel for personal use as opposed to a VPN to your corporate office for business). The tunnel between your machine and the VPN provider's network is completely secure, and any websites you visit will see the VPN provider's IP address, not yours. And typically the VPN provider does not monitor your traffic, so it's a fairly decent way to stay anonymous.
I used to use HMA VPN to download movies ($11/mo). The VPN allowed me to download movies and remain anonymous so the RIAA couldn't catch me. I don't do that anymore; got convicted of it since it is basically stealing. Edit: and yes, you can browse the Internet normally. |
