Ask HN: Do you know of any bootcamps for computer security?

I'm aware of all the bootcamps that have sprung up in recent years and these are almost all geared exclusively towards development/design.

I have a high interest in learning about the security side of things (vulnerabilities, hacking, etc) and have begun a recommended reading list starting with 'Gray Hat Hacking The Ethical Hackers Handbook'

I've always learned better though with a mentor/course and was wondering if anyone here knew of any bootcamps (or similar things) geared towards computer security.
