I haven't heard of any automated tools for pen-testing exotic communication
protocols, however as this document:
www.courts.qld.gov.au/qjudgment/ QCA%202002/QCA02-164.pdf
demonstrates, development tools and client software can be used to cause
mischief (assuming you've got yourself a wireless modem).

If your really up for an all expenses paid trip to cuba:

would probably come in handy.

Testing IP based systems could probably be achieved using normal pen-testing
techniques (assuming the softwares robust enough to handle the scan). I see
the major problem here is if a script kiddy compromised control software
sitting on a win2k box or similar

On a quick side rant - increased deployment on IP topologies may be a good
thing as we have lots of experience in protecting systems that use these
technologies (though the bad guys have more experience attacking them too)
than exotic protocols running over wireless (broadcast) networks.

I'm not convinced of the value of pen-testing SCADA networks (how do you
pen-test without causing damage? + most of the vulnerabilities are
blindingly obvious), but if you had access to a system prior to deployment,
a pen test might come in handy in convincing the boss that a bit of
encryption/firewalling wouldn't go astray.

Cheers,
dave
