Who said he’d use $CORPROSSID?

He’ll probably use Linksys, leave it wide open, and, you know, your internal network just became accessible to any script-kiddie on a nearby mountain top with a coffee can.

I’m going to guess that most IT managers and CSOs would be unhappy with that situation, but perhaps I am wrong.

And back hauling the AP’s traffic to some other (possibly evil) network is completely orthogonal to ANY of the threads in this discussion.

That doesn’t mean that 802.1x doesn’t address the issue exactly as you described. People argue all kinds of things and there are lots of networks that haven’t deployed 802.1x and/or strong authentication (WPA2-Enterprise, et. al).

Failure to deploy the tools doesn’t mean the tools and standards don’t exist.
