Leave it to Linus Torvalds, founder of the Linux kernel, to speak his mind. While many point to Linux as superior to Windows as offering superior security, Torvalds doesn't want anyone to make a fetish of security, including the OpenBSD people to whom he addresses this classic missive:
...[O]ne reason I refuse to bother with the whole security circus is that I think it glorifies - and thus encourages - the wrong behavior.
It makes "heroes" out of security people, as if the people who don't just fix normal bugs aren't as important.
In fact, all the boring normal bugs are way more important....Security people are often the black-and-white kind of people that I can't stand. I think the OpenBSD crowd is a bunch of [self-stimulating] monkeys....
I agree. Well, it's not that I have anything against the OpenBSD developers, or against anyone that makes security their job, but rather that I personally think computing has much bigger problems than code-level security. We've seen that human error (like lost laptops) leads to widespread security vulnerabilities that no amount of development can fix.
If I had to choose between a better UI for Linux and better security for Linux, I'd take the former every time. Users can improve poorly secured software by improving only behavior, but not if they won't use the software in the first place.
