Information Security: It's the Economy, Stupid
...We generally think of computer security as a problem of technology, but often systems fail because of misplaced economic incentives: The people who could protect a system are not the ones who suffer the costs of failure.
When you start looking, economic considerations are everywhere in computer security. Hospitals' medical-records systems provide comprehensive billing-management features for the administrators who specify them, but are not so good at protecting patients' privacy. Automated teller machines suffered from fraud in countries like the United Kingdom and the Netherlands, where poor regulation left banks without sufficient incentive to secure their systems, and allowed them to pass the cost of fraud along to their customers. And one reason the internet is insecure is that liability for attacks is so diffuse.
In all of these examples, the economic considerations of security are more important than the technical considerations. Wired News: It's the Economy, Stupid
