RE: How does a customer get PCI audited?

Hi,
Actually I did read it. You should also note that I did not state that you do not test. Rather I stated as in the 
papers I have published in the past that Red teams are less effective than Blue taking a number of assumptions of equal 
skills etc into effect.

Pen Testing is "sexier". It is not as effective as other forms of testing and validation. It is the easier sell.

"The unfortunate truth is that MOST businesses that provide "auditing"
type services, or assessing type services do not know what they are doing."
I agree. The same goes for over 90% of red teams. This argument is a red herring that applies to each argument equally. 
Most "Pen Testers" are equally clueless. So what is the argument?

Actually, common sense is something that fails more than not. Most of science in the 20th C turned against common 
sense. We are a species that has developed to suit an environment that no longer exists. This is why we measure 
perception and call it a measurement of security.

You state that a firm needs to be "tested at the same or higher threat level as you'd face in the real world."
Please answer how?

Real world threats are never tested by red teams. Not even military ones. A cut down attempt is made. You can simulate 
the script kiddie, but not the Dragon's.

In the 90's I did some "real" red team work. With pieces of paper from government agencies in case something went wrong 
we even did a number of actions that are technically illegal minus the "get out of free card".

When was the last time your red team kidnapped somebody? When did you pay an employee $50k to see how they react? I 
have seen all this in the "real world". I worked on a case where an Asian bank manager was sent parts of his daughter. 
Sorry, but controls that added a distress code helped more than a pen test. So did segregation of duties (to qualify, 
it helped the bank).

So how DO you test segregation of duties on a database system using a pen test?

Even from a physical limitation removed perspective with access granted, how common is it to map internal business 
processes in a pen test? Security is not just "hacker" style vulnerabilities. It also involves tests of the payroll 
processes, HR systems, reporting engine, etc. The general vulnerabilities account for less than 1% of real issues and 
problems I come across in forensic work.

Running a scanner is not an audit. If a firm states it is, take them to court for false or misleading trade practices. 
I would be happy to sue their ass off for such a lie.

Yes, I will agree there is a place for pen testing. I am one of the question authors for the SANS GPEN cert so I have 
to have some support for the concept. It is NOT the be all of security as it is made to be. As noted, Pen Tests are a 
detective control. These controls are by nature essential, but they are also quantitatively less effective than 
preventative controls.

" it is very hard to find good vendors these days."
This I agree with completely.

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.

No, good controls and training help secure a system. Pen testing is a detective control. No more. In fact, it is not 
even close to being the best (bang for buck) detective control.

Actually, Pen testing is about a 30% option that ignores many of the vulnerable points of a system. Economic limits 
constrain it. The difficulty

I did some scientific research into this in the past. I published in the IIA journal and a few others and a paper is 
on the sans reading room as well:
http://www.sans.org/reading_room/whitepapers/auditing/1801.php

The difficultly is that there are very few auditors with a deep technical level of knowledge.

Craig,
        You secure your systems by having an IT Security Company perform a real
good assessment. It should be either a Penetration Test or a
Vulnerability Assessment. Penetration Tests are more in-depth,
Vulnerability Assessments are more safe. If you want information on both
of those services I've got a few white-papers that we've written that
you can download. Unfortunately, it is very hard to find good vendors
these days.

PCI Top level = 100%
A break-in occurs = 99.5%

A better question is how do I pass an audit and better yet, how do I secure my systems.

PCI-DSS is just the tip of the iceberg for potential issues. In fact it is the low risk consideration. Think class 
action. PCI-DSS compliance is at least a small defence. That is being ACTUALLY compliant and not just doing enough 
to fool the QSA.

Subject: How does a customer get PCI audited?

I have a client (same one from a previous post) who has some pretty
serious security issues on their network (unsecured .mdb file with
credit card into, etc).  I will be fixing the major security holes in
their network, but they still have PCI compliance issues, and I'm
assuming they need to have a quarterly scan done.

They've had this setup for about a year, they knows nothing about PCI
and compliance (myself included, I am not a QSA and still learning about
the compliance procedure).

What are the chances of them getting audited?  How does all that work?
Could they potentially fly under the radar for years?  I thought there
was something they had to report quarterly to show they're working on
compliance, or something.

I want to be able to tell they company "Listen, here's what could happen
if you get audited, and here's the chances of you getting audited" in
hopes they would take it seriously.  I don't want to scare them without
knowing the facts, first I want to know the facts, then I will scare
them.  Thanks.
