This example is about test scores in education. Obviously, it could apply to other security problems as well.
Changing Incentives Creates Security Risks
An interesting example of this is the recent scandal in the Washington, DC, public school system over teachers changing their students' test answers.
It turns out that a lot of those score increases were faked. In addition to teaching students, teachers cheated on their students' tests by changing wrong answers to correct ones. That's how the cheating was discovered; researchers looked at the actual test papers and found more erasures than usual, and many more erasures from wrong answers to correct ones than could be explained by anything other than deliberate manipulation.
Teachers were always able to manipulate their students' test answers, but before, there wasn't much incentive to do so. With Rhee's changes, there was a much greater incentive to cheat.
The point is that whatever security measures were in place to prevent teacher cheating before the financial incentives and threats of firing wasn't sufficient to prevent teacher cheating afterwards. Because Rhee significantly decreased the costs of cooperation (by threatening to fire teachers of poorly performing students) and increased the benefits of defection ($8,000), she created a security risk. And she should have increased security measures to restore balance to those incentives.
This is not isolated to DC. It has happened elsewhere as well.
