Fingertips

From today's Austin American Statesman, this article discusses the fraud deterrent effect of fingerprinting applicants for food stamps, and if it is worth the delay it may be causing in processing (Department of Agriculture says it isn't).
There are lessons to be learned at Texas HHSC.
Starting here:

The electronic fingerprinting program costs $3 million a year: $1.6 million for a contract with Cogent Systems for the imaging and $1.4 million for state workers' time. The state and federal governments split the cost.

Last year, the fingerprint program led to the state investigating just four applicants for fraud.

But state officials say it's impossible to know how many people are deterred from applying multiple times because of the fingerprinting.

But later in the article:

The state estimates that the deterrent effect of fingerprinting saves $6 million to $11 million a year.

I imagine the latter figure could have been pulled from cost justification of the project, or from the vendor's response to the RFP, or even the LBB when the law was passed. (Does the cost include the initial implementation of the system?) But measuring the actual decrease in applicant fraud is a solvable problem. To say that there is "no way of knowing" the deterrent effect is not defensible. If they never measured a baseline of applicant fraud to begin with, how would they have known how much to spend on an anti-fraud measure? If they don't try to measure the change post implementation, how do they know it's working?

On the other, more cynical, hand, why should they care? They are in compliance with the state law, and the system was implemented. The only people who suffer are the citizens who need help to buy food. Folks who may not be able to take off from their minimum wage job, or don't have the transportation, to go be fingerprinted. Measuring the dignity of your customers is harder than measuring your fraud deterrence cost.


You tell 'em Stevie.

Segregation of Obscurity


From Forbes account of the Societe Generale billion dollar fraud:

"It's Nick Leeson, the story is exactly the same," said Celent's Pierron. "We have a trader who trades futures, or derivatives, who hides his losses by using weaknesses in the risk-management system." He said that as long as traders had knowledge of back-office operations, the risks of
abuse would always be there.

A spokesperson for Societe Generale said that there would be thorough reviews of internal controls, but noted that this particular case of fraud was "very, very sophisticated."
So, segregate controls, but keep them obscure.

Confusion In My Eyes That Says It All


I figured I'd wait until after my paternity leave was over before I started thinking seriously about words like "control" and "compliance," but I felt the need to say something after reading Bejtlich's post "Controls are Not the Solution to Our Problem."

He illustrates through citing an example of a control, and identifying ways that it fails to achieve total effectiveness. The control may not work and could be superfluous. His alternate approach is a system of assessments, tests and monitoring coupled with a rigorous set of metrics.

If someone describes an asset as "secure," "safe" or "reliable," my job as an auditor is to ask the question "How do you know?" The answer is a control. Bejtlich's "field-assessed" approach is another set of controls, mostly detective rather than preventative. What happens when his approach is codified into a government procedure or a vendor contract? A security practitioner with a preventative approach could grouse about how these pen tests and honeynets don't address the security needs in his shop (due to scale of operations or type and level of risk).

Tossing out controls is also just not an option. Effective or not, compliance keeps you out of jail. I don't always feel that on some roads a 55 mph limit is a necessary control to prevent accidents, but that will mean I am not breaking the law when I speed.

I'm not as big a proponent of metrics as a control solution, but I'll leave that to another post.
