So, most of you are suggesting to have WPA in place at home?
How does this work in terms of authentication for home users? Ie, how does
someone establish a secure link to a Radius server on the network? Or have I
got this back to front? I'm assuming that there has to be a Radius in the
auth process somewhere.

Ahhhh!!!!!!

Child's play. No encryption and just about anyone
could get access to that machine with very little
effort.

Not easily, for 90% of companies this is pperfectly
secure. If the intruder was able to get in, then yes
they could get access to your network. WEP isn't
great, but in most cases it's secure enough.
Especially if you're then going to wrap it in a VPN.

Are you talking abour wireless? Probably no more that
he is running around a hotel with a laptop without
wireless. Do you encrypt everything on the laptops? If
not, it would be easier for someone to steal it than
it would be to steal traffic on an encrypted link.
Someone who wants information is going to go for the
low-hanging fruit and grabbing a latop while someone
isn't paying attention is way easier than trying to
hack into it.

If you're workforce has wireless enabled notebooks,
you're much better off allowing them to use it and
using best practices to keep the information safe.
Wireless is too convenient. If you forbid them from
using it they're going to work around it and use it
anyway and then they won't be using any security
measures.
