It was bothering me for a long time that I didn't find evidence of any 
enterprise of size wanting to even purchase "seats" for source code scanning by 
developers yet I find tons of evidence that folks want to have deeper audits 
and have the tools in the hands of a few. One cannot ignore the importance of 
the thud factor when the report comes out especially in organizations that are 
led by process weenies who aren't really technical.
 
I do believe that enterprises would entertain tools that enabled secure design 
and figure out a way to apply security patterns such as what is outlined in the 
Core Security Patterns book. Tools that could somehow automate 
architecture/design reviews would be of immense value as well. 
 
One interesting thought I have is that more developers may care about secure 
coding if there were statistics that compared American developers to those 
employed in other countries. Right now, outsourcing is an unpopular topic where 
folks respond based on how they feel. Imagine the press if folks could 
factually prove that folks in other countries increase security defects...

I really hope that this email doesn't generate a ton of offline emails and hope 
that folks will talk publicly. It has been my latest thinking that the value of 
tools in this space are not really targeted at developers but should be 
targeted at executives who care about overall quality and security folks who 
care about risk. While developers are the ones to remediate, the accountability 
for secure coding resides elsewhere. 



Nice email James. These conversations are always enlightening. The responses 
tend to illuminate who has what experience types, between (a) university 
software experience, (b) government software-project experience, and (c) 
enterprise software experience. That makes a lot of difference in these 
discussions. Most enterprise /and/ small ISV developers I know, the good ones, 
either take pride in their quality of code and self-manage security issues, or 
are fast and productive and don't give a crap. 

And why should they give a crap? It's not their problem domain.

The armchair software-security pundits: "Shame on you. You didn't properly 
transcode these Hebrew and Latin code pages to avoid XSS attacks, dummy." 

The fast effective developer: "I delivered your functional specifications to 
the letter, on time, and the transcoding engine is FAST. What's the problem 
here?"




It would seem to be that tools that developers plug into their IDE should be 
free since the value proposition should reside elsewhere. Many of these tools 
provide "audit" functionality and allow enterprises to gain a view into their 
portfolio that they previously had zero clue about and this is where the value 
should reside. 



So of tools that plug into the IDE, let's distinguish between *source-code* and 
*run-time* "scanners". Source scanners I suspect will die a slow death, because 
sooner or later they are going to integrate into the IDE and per-seat value 
will plummet. They will be a "given feature" of IDEs. Sooner or later the IDE 
vendors will either buy & integrate, or come out with their own tools. Take 
Compuware, the quality is pretty low, but if I were a betting man I would bet 
that the bar gets set at "low-quality included-functionality" rather than set 
at "$50k per-seat amazing quality source code analzyer". 

I believe this is different from run-time or human design analysis, largely 
because of different business case.

For example: I have some clients that really like their Fortify tools, but they 
really don't like all the time and critical development resources it takes to 
use them, and how expensive they are. Cool tools, sexy technology, but they are 
hard to align with the business case and business goals for software 
development on multiple levels. 

Run-time analysis is different. Run-time "scanner" IDE-plugins as a concept is 
laughable, at best. Seriously -- who thinks that run-time scanners for 
developers is a viable idea?

 Run-time analysis's strengths are different too. It is easier at run-time to 
discover and analyze fundamental design flaws (note: I did not say "find them 
all", but definitely "find indication of them"), and to identify emergent 
behaviors. At best IDE plugins can perform some form of unit testing, but 
beyond verification of basic data-typing and IFOF/IFOE type issues, meh, not 
very useful. Not to mentioned entirely outside of the IDE problem-domain. 

Conclusion: two sets of problems, source analysis, and run-time analysis. I 
think there is a good-enough bar for source analysis that will get set fairly 
low and wind up baked into IDEs... similar to the Viz Studio /GS switch. I've 
already seen a pretty effective one that will probably wind up in one of the 
next releases of Visual Studio. It's actually better than some of the 
commercial offerings today, and baked in. 

Spot on James.

Human source analysis for Design Pattern issues, I think, this will always be 
needed. Same for run-time analysis. Different problem-domains they solve for 
though.




If there is even an iota of agreement, wouldn't it be in the best interest of 
folks here to get vendors to ignore developer specific licensing and instead 
focus on enterprise concerns?



So some marketing guy one day grokked "there are only n-number of security 
people per organization that scan run scanners, but there are Multiplier(n * 
33.5) number of developers per organization....wow! We could sell all those 
developers scanners!!! Ka-Ching."
 
That sort of thinking is pretty cool, leads to some cool sales growth graphs 
and profitability projections. Need board-room meeting material, fits perfectly 
into that circular-arrow graph everyone has with "TCO" and "Lifecycle 
Management" and "ROI" and how it all loops together and saves everyone big bags 
of money after they spend up front. 

This circular "lifecycle-management" graph is labeled Security in the SDLC and 
shows how you can buy a lot of developer/IDE-scanners and have even the 
cheapest developers scan their code up front, and you'll save big in the long 
run by avoiding those expensive security audits, compliance issues, and having 
your smart (expensive) developers have to go back and fix all those holes. 
Ka-Ching. 

I haven't heard the business plans of any of the source-code-scanner vendors in 
a year or two...but back then, I didn't hear one that aligned with any 
enterprise software development or business plan reality that I have 
experienced. 

My thinking here could be off. I thought WAFs were a ridiculous idea but I'm 
starting to see very effective use-cases for them, despite the ridiculous 
claims and hyperbole that come from the WAF-vendor marketing nonsense. 

Anyway, I think you are spot on James, and I think if you look at Gartner's 
recent punditry you'll find some similar notions expressed.

Chow,
