it-propoganda-i-dont-think-so

The anonymous CEO blogger has accused me of IT propoganda. Don't worry my feelings aren't hurt ;). Of course, it is in my interest as the CEO of a security firm that more CEOs recognize the value that investing in security brings. However, I would point out a few things that IMO, keep this post from being pure 'propoganda'.

security-through-lingual-obscurity

On a recent trip to Mexico, our casita had a safe in it. The instructions for using it and the combination were printed on a covered sheet of paper sitting on top of the safe. As I scanned for directions on how to change the combination, I read:

security-and-oil

I've been reading The Prize by Daniel Yergen. I've wanted to read it for quite some time and just ran across a copy at a yard sale. It is excellent. I'm about half-way through.

infosec-and-the-affect-heuristic

Perhaps there is a lesson for infosec professionals in this post on the Affect heuristic on Overcoming Bias:

Suppose an airport must decide whether to spend money to purchase some new equipment, while critics argue that the money should be spent on other aspects of airport safety. Slovic et. al. (2002) presented two groups of subjects with the arguments for and against purchasing the equipment, with a response scale ranging from 0 (would not support at all) to 20 (very strong support). One group saw the measure described as saving 150 lives. The other group saw the measure described as saving 98% of 150 lives. The hypothesis motivating the experiment was that saving 150 lives sounds vaguely good - is that a lot? a little? - while saving 98% of something is clearly very good because 98% is so close to the upper bound of the percentage scale. Lo and behold, saving 150 lives had mean support of 10.4, while saving 98% of 150 lives had mean support of 13.6.
The post also shows that people tend to over-estimate the value of going with known brands, even though they might not add any extra value:
Ganzach (2001) found the same effect in the realm of finance. According to ordinary economic theory, return and risk should correlate positively - or to put it another way, people pay a premium price for safe investments, which lowers the return; stocks deliver higher returns than bonds, but have correspondingly greater risk. When judging familiar stocks, analysts' judgments of risks and returns were positively correlated, as conventionally predicted. But when judging unfamiliar stocks, analysts tended to judge the stocks as if they were generally good or generally bad - low risk and high returns, or high risk and low returns.
But perhaps you don't have time to consider all this, because you've got a deadline!
Finucane et. al. also found that time pressure greatly increased the inverse relationship between perceived risk and perceived benefit, consistent with the general finding that time pressure, poor information, or distraction all increase the dominance of perceptual heuristics over analytic deliberation.

schneier-questions-need-for-himself

I read with delight this quote from omnipresent security pundit Bruce Schneier questioning the reasons for the existance of the security industry:

"We shouldn't have to come and find a company to secure our e-mail. E-mail should already be secure. We shouldn't have to buy from somebody to secure our network or servers. Our networks and servers should already be secure."
