"Just out of curiosity how are you defining a "Pen Test"?"
Pick any of the definitions, right up to full red teaming.
"but you give no examples of other more effective forms of testing."
I have stated audit - correct with knowledgeable people (which is rare I know) to you many times. A good audit of a
system will validate a system. If actually done, this is more in-depth than a pen test.
"Common sense doesn't fail more than it succeeds, if it did
then we would not survive as a species."
That is not correct and demonstrates a misunderstanding of evolutionary theory. Evolution does not favour being
smarter. In fact the base IQ of most native groups that life a hunter gather existence is higher than that for modern
western society. I can send some research papers if you like.
"Testing at a higher threat level means performing research against the
target to be assessed. Often times that involves performing a review of
historical IDS events, a review of the targets policies and procedures,
and gaining an understanding of what they have that is of value that
others want. Another helpful aspect is to be able to keep tabs on what
sorts of 0-day threats exist, which we can do."
The comment again is a red herring. It applies to all aspects of security if done effectively and is designed to throw
one off without adding anything. This needs to be done as a pen tester, auditor or whatever else.
"Are you suggesting that a talented, financially oriented malicious hacker with intent to extort his or her victims is
not a real world threat?"
NO, I am suggesting the opposite - that no pen test does a high level analysis to the level of a high level attacker.
"Or are they not real because they do not come wielding hand grenades and guns? Are they not real because they never
Again you are being ridiculous to try win a point through other means. Nothing of the type.
"We're not in the 90's anymore, that's 18 years old."
Actually it is 9 years old - it did not state 1990 do the maths and please stick to the topic.
"I see many more people suffering because of "hacks".
I see most due to actual things that matter, fraud, theft of intellectual property, corporate espionage, breaches of
"So now you are talking about policies and procedures that are far out of
the scope of where this discussion started."
Again you "choose" to miss the point. Pen testing is better to you as this is what you sell and thus there can be no
">Even from a physical limitation removed perspective with access
granted, how common is it to map internal business processes in a pen
For my team, very common.
"A good team capable of real testing will test those processes and
Show me an example. I do pen testing, I just am honest enough to tell my clients that there are better options for
testing and managing controls. Even stating this firms want the "sexy option" as I stated.
Next, to add to "For my team, very common". We have US clients. As an auditor (real audit firm, not security tester but
auditor as per corps act etc) I have the legal right to ask for testing documents. This is all pen test reports etc.
This included groups ones from the US.
I look through Pen test reports weekly. I have seen ones from your firm in the past. I will give you that they are
better than most. I shall also state that before you try arguing that they are confidential, remember, audit firm and
the right to have any and all documents we wish to see under law. These are a security control and thus I have a legal
right and responsibility to view them.
With this I would state, either you misunderstood the comment or I happen to be unlucky enough in the (approximately)
2500 pen test reports I have reviewed and the 40+ this year alone to have missed every example of what I suggested as I
have never received a report from pen test that actually tested business processes.
"Penetration Tests identify those risks if done properly by a capable team."
Pen testing identifiers a limited subset of risks.
It (a pen test) does not test security. It is a form of failure model testing. A system that a pen tester could not
compromise is not in a secure state for this reason - it just means that no critical state was discovered.
