Re: How does a customer get PCI audited?

[Adriel Desautels <adriel () netragard com>]

Craig,
	I'm afraid that you didn't read what I wrote carefully enough or that I 
wasn't sufficiently clear in my communications. If you go back and read 
what I said, I explicitly used the words "real" and "good".

	You can be purple in the face with controls and training, but if you 
are never PROPERLY tested by a REAL team then you will never know where 
your REAL risks are. The end solution consists of the PROPER 
implementation of controls mixed with the right amount of training. You 
can't create a GOOD solution without knowing details about the problem.

	The unfortunate truth is that MOST businesses that provide "auditing" 
type services, or assessing type services do not know what they are 
doing. In fact, very sadly most of them run automated scanners and 
produce deliverables that are the product of those scanners. Those 
deliverables should be free in my opinion as they are usually poor quality.

	In order to properly defend a network you must first know what you need 
to defend it against. You must have a strong understanding of the threat 
and how the threat might align with your risk and exposure profile. The 
only way to do that is to either have good threat intelligence, or work 
with a qualified penetration testing team that has REAL threat 
intelligence.

	Once you've identified such a firm your IT Infrastructure, personnel, 
policies, etc. need to be tested at the same or higher threat level as 
you'd face in the real world. That will identify your risks and help you 
to build the proper CONTROLS to counter those risks. Suggesting that 
anyone build controls without first having a GOOD and REAL assessment is 
horrible advice. That would be akin to building defenses against Russia 
during the cold war with no intelligence about their capabilities.

	With respect to your paper, I still need to go read it. That said, even 
if Penetration Testing is 30% of the total solution, it is clearly the 
foundation to building the solution. Else you are building a blind 
defense that most probably won't work.

	Its common sense Craig, know your enemy, know yourself, and then you 
can build a good defense.
