I'd say it differently, though. Instead of defending the original point, which was bad, I'd instead say among all other controls--most important of which is patching, removing passwords, etc.--one control is running below 1024.
I could go for that.
Except I actually think the gain from being up high (over 60K) is greater than the gain from being below 1024. It's not about being invincible, it's about not being a target at all.
