Craig,
Thanks for that information. I have an additional question that is purely
hypothetical
which also tangentially related to the WEP cracking in airports. In the space
around
where I work, there are approximately 200 different access points that are
visible
from within the space I work that are not owned by us. Presently I only use
netstumbler
/ kismet to ensure that the devices are not present in our environment. If we
had
a device that was in ad hoc mode, then it could potentially indicate a breach.
If I wanted to capture packers to investigate our network further, there would
be
a high degree of probability that I would inadvertently capture packets from one
of the other 200 different networks invading our space. It sounds like, because
those wireless networks invade our space, that I would not be permitted to do so
because I would be in awareness that I would also pick up other wireless
networks.
Luckily, even with the audit follow-ups, I've never needed to do so, but I could
imagine an incident occurring where I may need to capture traffic (authorized
relating
to our own network), but I may even inadvertently capture plain-text passwords.
This may be a good opportunity to update my forensic procedures to include
wireless
breaches and update incident response surrounding wireless networks. Any
thoughts?
Matt

"sniffing the air" is legal
Well actually, if this is sniffing as in intentially capturing an electronic
transmission, than this is illegal and also criminal.
Interecption + telcomunications - permission = criminal act
this is true in the US, CA, UK, AU etc
So actually even capturing packets is illegal, proof is difficult though.

Craig
