Sharing Internet Connections?
2006/04/30This study out of the University of Illinois at Urbana-Champaign sounds great:
Software Allows Neighbors To Improve Internet Access At No Extra Cost
The way they are accomplishing higher throughput makes sense: use
multiple paths. However, I'm not so sold on how secure this will
necessarily be. The software has some allowances for security but
basically it means willingly allowing another onto your private
network. Don't get me wrong. Wireless as implemented in most homes
isn't anywhere near to secure, however, I think this type of solution
may present folks with a false sense of security: "This software
handles security for me so I don't have to do anything else."
A couple of years ago I saw a presentation at Black Hat about how firewalls and the concepts we have for perimeter-based security models aren't going to cut it in the future
Thinking Outside the Box–Embracing Globalization). The trick then is to
ensure each individual system is secure and that they talk with each
other using secure mechanisms. While this may end up being the rule in
the enterprise, I doubt the average home user is going to get to a
point where he or she is going to be able to lock down a computer
system to be reasonably secure in an environment such as this.
