What's the Opposite of Openness?

Not simply being closed, but something like this:

If I make a computer security mistake — in a book, for a consulting client, at BT — it’s a mistake. It might be expensive, but I learn from it and move on. As a criminal, a mistake likely means jail time — time I can’t spend earning my criminal living. For this reason, it’s hard to improve as a criminal. And this is why there are more criminal masterminds in the movies than in real life.

BTW, this interview with security god Bruce Schneier is just amazing - not least because it goes on for ever. Luckily, you just can't have too much of Brucie.
