Hi James,

I think you are right to look at it as economic issue, but the other factor
to add into your model is not just the short term impact to developer
productivity (which is non-trivial), but also the long term effects of
making decisions *not* to deal with finding bugs.

Cleaning up data breach costs more than encryption

Protecting customer records is a much less expensive than paying for
cleanup after a data breach or massive records loss, research company
Gartner said. Gartner analyst Avivah Litan testified on identity theft
at a Senate hearing held after the Department of Veterans Affairs lost
26.5 million vet identities. A company with at least 10,000 accounts to
protect can spend, in the first year, as little as $6 per customer
account for just data encryption, or as much as $16 per customer account
for data encryption, host-based intrusion prevention, and strong
security audits combined, Litan said. Compare [that] with an
expenditure of at least $90 per customer account when data is
compromised or exposed during a breach, she added. Litan recommended
encryption as the first step enterprises and government agencies should
take to protect customer/citizen data. If that's not feasible,
organizations should deploy host-based intrusion prevention systems, she
said, and/or conduct security audits to validate that the company or
agency has satisfactory controls in place.

 Thanks for the response. One of the things that I have been struggling to
 understand is not the importance of using such a tool as I believe they
 provide value but more of the fact that these tools may not be financial

 Many large enterprises nowadays outsource development to third parties.
 Likewise, the mindset in terms of budgeting tends to eschew per developer
 seat tool purchases. Nowadays, it is rare to find an enterprise not using
 free tools such as Eclipse and not paying for IDEs
 
 I have yet to find a large enterprise that has made a significant investment
 in such tools. I wonder if budgets and the tools themselves are really causing
 more harm than helping in that enterprises will now think about trading off
 such tools vs the expense they cost.

Hi All,
 
Just a quick reminder that there is a chapter on code scanning technology and 
its application in Software Security (www.swsec.com).  Don't forget that 
these tools are best used as aids to make a smart human more efficient.  They 
do not replace the human, nor are they of much use among the clueless.  Every 
commercial tool has its issues, but the free tools ITS4, RATS, and flawfinder 
are not worth using at all anymore given tool evolution of late.  The chapter 
in Software Security discusses the history of these tools, how they actually 
work, and points to research in academia so you know where they're headed.  
There are also pointers to most of the commercial tools.
 
We have found in our practice at Cigital that the most powerful applications of 
these tools involves developing specific and tailored coding guidelines for a 
given platform (say J2EE), building those guidelines to just so happen to 
cohere with security policy (shhh, tell no one), and then enforcing the 
guidelines by adding rules to a static analysis tool.  
 
Another tip: don't use the tools with all of the default rules all at once.  
Carefully turn rules on and off and feed the results into dev along with 
training.  Use the tools as part of awareness and enforcement activities.

Fortify

Fortify is aimed as a tool for use in a security audit.  It is
deliberately biased in the direction of flagging all potential
security issues.  It provides two kinds of analysis - what they call
semantic and data flow.  Neither use of terminology is consistent
with industry practice.  Their semantic analysis is better described
as a syntactic analysis:  It looks at surface features of the
program (use of certain calls, for example).  It mainly ignores
context.  Fortify's own representative describe this analysis as a
super grep.  This analysis is driven by a large database of rules,
which can be extended.  (In industry practice, a semantic analysis
would look deeply at the meaning of the program.)

Data flow analysis is better called taint analysis.  It traces all
data

Several thoughts:

1. I love it when industry analysts are perceived as being credible by throwing 
out financial costs for things they really don't have visibility into.

2. The VA lost data not do secure coding techniques but an employee not 
following the rules on what data to take out of the building.

3. No industry analyst has ever attempted to quantify cost vs benefit of secure 
coding when compared to other constraints. The quantification to date has only 
been the cliche: it is cheaper to fix X earlier in the lifecycle rather than 
later in which X could be pretty much any system quality.

Hi James,

The point is going back to your original question --  I wonder if budgets
and the tools themselves are really causing more harm than helping in that
enterprises will now think about trading off such tools vs the expense they
cost. -- the economic comparison needs to take into account the tradeoff
not just the expense of the tool, developer productivity, and bug
remediation early v. late, but also the breach itself has a cost when those
bugs that are not dealt are eventually exercised. So I don't care if you
don't like the Gartner numbers, you can use others to weigh the cost of the
breach (Ponemon's are higher actually), but whatever number you choose to
use should be factored in to your model to account for this. It may not be
helpful if not scrubbing in allows your surgeons to operate on more patients
if they are killing them faster due to infections they cause.
