VPN

It's virtually private.

You're running late at work. You have a bunch of stuff to bring home for that big presentation in the morning. You gather your things together, fight the traffic, arrive at your humble abode and sit down for a night of slaving for the man, and then it hits you.

That one file you need is on the server at your office, and the table of contents is on the desktop of your office computer. What now?

This is just one example of the joy of using a virtual private network, or VPN. Sure, you could use GoToMyPC (which is a retail service-bureau version of a VPN), and people often do. Or, your company can set up a private, encrypted, direct access path that lets you log in to their network, and access any of the same resources you'd have if you were sitting at your desk at work.

More than just a way of logging in to your work PC, a VPN allows the company to use strong encryption tools, secure login methods and robust file transfer protocols to let workers extend their workspaces to anywhere they can access the Internet. You company assigns you a VPN login and password, plus gives you special software (and sometimes hardware) that makes access to the VPN possible.

And you can even do the reverse: if you work from home, Linksys and other manufacturers have special VPN-enabled versions of home broadband routers that you can set up with your very own virtual private network and login to your home PC network from anywhere in the world.

So just think - you can remind your kids to do their chores by printing a quick "TAKE OUT THE TRASH" in 72-point Verdana on your home printer, from that Internet cafe in Morocco - just be sure to have set up your virtual private network ahead of your trip.

Product Description
This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A607683. The abstract provided by the Pentagon follows: As broadband connections to the home become more prevalent, through Digital Subscriber Lines (DSL) and cable modems, students and faculty will desire to access the NPS Internet via these new means instead of their 56K modems. The introduction of these new technologies will require NPS to re- evaluate how to allow remote access to their internal resources in a secure way, while still allowing for the use of broadband technologies. This thesis will examine the alternative methods for implementing VPNs, from simple use of Point to Point Protocols (PPP) to high end specialized internet appliances and gateways. Pros and cons of each will be discussed. A mock-up of the schools network will be created to test each of the discussed methods. Final recommendations will be made for a model that can be used by the NPS to implement a VPN. Also discussed will be how that model may be altered to fit other commands throughout the US Navy who desire similar secure remote access to their internal network resources.
