In some email I received from Marcus J. Ranum, sie wrote:

I find a lot of IT is just "commonsense engineering", but how things
go so wrong is a mystery.  Well, I guess if you're forced to use
broken tools, what can be expected but a mishapen result ?

But so many programmers working on "Security Sensitive" code are not even
aware that there are published security coding practices, and buffer
overflow testing tools similar to the ones available for memory leakage
testing. More than once I have had extended (and sometimes loud) discussions
(read: arguments) with senior programmers who were supposed to hae
"significant" security programming experience. 

I should have been more clear in my terminology: I meant that you
don't need to run around with a big encrypted CDROM full of your
toolz to be a security guru. You need to understand the forms and
functions of categories of attacks so you can defend against them
or design around them as _categories_ - having specific knowledge
(or toolz) to break specific versions of software on specific
architectures -
that's just lame script-kid stuff. And there are a kit of "security
analysts" whose level of expertise is more in the script kiddy vein
than not. Perhaps we should call them "Scanner-kiddies" ? ;)

Careful Marcus, it is starting to sound like you're justifying things
like CISSP that teach you lots about nothing ;-)

Maybe you should start offering courses in security and give out
certificates titled MRCRISP (Macrus Ranum Certified Real Information
Security Professional. :-)

The biggest differentiator that I have seen is whether any particular
security consultant/professional has an understanding that security is a
Risk Management process and a Business Continuity Planning issue. 

In particular in terms of Risk Management: "Dont spend more on securing a
service than you would lose through it's compromise or destruction."

To many "Security Professionals" are IT Geeks who have decided "Security
looks cool", so added a veneer of security tools and buzz phrases (to a
lesser or greater depth of understanding), rather that people who have added
an understanding of IT, process, and risk to an understanding of security
concepts (such as separation, depth, response and timeliness) and models.
