Of course, and Paul's later statements on the issues, he was the
individual that Ben was quoting, go further. Paul's assesment is:

Paul D. Robertson:
I'm not sure you can know that accurately when blind. That's actually
probably my biggest problem with blind tests- the tester doesn't get to
see the configuration file that could contain the backdoor from hell.
I'll give you an example. Let's say that a company's administrator is
attending a local university, and to make life easier, allows access to
the administrative ports of his infrastructure (routers, switches and
firewalls) from the university's lab so that when his pager goes off, he
can fix things without missing too much class time. A blind test won't
find that. A configuration check can.

The full discuassion is quite well done, and a danged good read. I
recommend others here look at the firewalls list archives of the past few
days.

Thanks,
