I read this story on CNN and it really made me pause and think about how vast the world of possible terrorist targets really is. In a nutshell:

Researchers who launched an experimental cyber attack caused a generator to self-destruct, alarming the federal government and electrical industry about what might happen if such an attack were carried out on a larger scale, CNN has learned.

I suppose it is better to learn this in a test so we know what our vulnerabilities are. Suffice it to say, that I wonder the value of knowing the vulnerabilities if there are neither plans nor funding to fix them?
