Positive impact of an SSG

[chandra at list.org (Pravir Chandra)]

Yes, I don't think its exclusive to your BSIMM interviews that you found when people put controls into place, they saw 
improvement. That's what I (and I'm sure many other consultanting firms) have been doing for years based upon previous 
models (CLASP, MS SDL, etc.). Nothing to do with BSIMM per se (actually, most of what DTCC started doing was based on 
CLASP), just that they added controls 'early into software development lifecycle' and saw benefit, which isn't 
surprising.

That being said, the important part we're missing as 'software security guys' isn't the specification of all the 
possible things that an organization *could* do, but rather what a given organization *should* do based on good 
business decisions around risk management. And that's the crux of what BSIMM fails to do. By basing the current 
maturity model on the collected practices of 9 massive firms that spend the most on that problem, anyone (aside from 
firms in a similar situation to your 9) that attempts to apply it to their organization effectively throws risk 
management decisions out the window and commits to a much more costly solution than they could have created based on 
the knowledge of their own business needs since all the practices are based solely on the behaviors of the select few 
firms you interviewed. I'm not discounting the validity of the empirical data, I'm just positting that it isn't 
scientifically valid for solving the problem at hand.

I'm interested to hear what you learn when you get to the small and medium sized businesses as well as firms using 
agile development models (something I particularly considered and accounted for with SAMM). 

Regardless of whether we agree on the percentage of orgs for which a dedicated SSG isn't cost effective, I'm sure we 
can agree that affording 'someone in charge of success' doesn't equate to a dedicated SSG. There's a myriad of ways 
that can be accomplished in any organizational structure.

Thanks!

Hi Pravir,

Yes, I agree completely: the data gathered in the BSIMM interviews seem to indicate that "the controls over all" led to 
what the interviewees saw as improvements in their capability to produce secure software.

In the nine companies interviewed, those controls (BSIMM activities, I think) sprang from well established SSGs -- that 
is, a specific person or persons with the responsibility for ensuring lots (110, collectively) of activities actually 
get done.

The BSIMM data to date from specific large organizations indicate that a little under 100:1 is the average ratio for 
dev/QA to SSG size. It'll be interesting to see how this changes when we get to interviewing smaller organizations and 
we see if and how they're actually getting it done.

Personally, I don't believe I agree with your guess that 95% of organizations building code can't afford an SSG. I 
believe every organization that wants to succeed can afford to have someone in charge of success, but that's just my 
opinion and isn't relevant to BSIMM.

Cheers,

--Sammy.

Hey Sammy.

How does that pertain to a software security group (SSG) per se? The
details below seem to indicate that it was the controls over all that
lead to the positive impact.

My main point is that supporting an SSG isn't cost effective for 95%
of the organizations out there that are building code. That's why in
SAMM, we didn't mandate the structure of the organization and instead
concentrated on the functions fulfilled by security guys (regardless
of their placement in the org).
