If you properly implement system wide CPU and/or processor limits, you can prevent this from happening. you can enforce it globally or only for certain users. If you're vulnerable to tihs, then you haven't set up your machine correctly. (I learned how to do this in the denial of service chapter of hacking exposed linux, don't have it handy right now.)
The Debian security manual is indeed excellent. I'd strongly vote against the Maximum Security books - they are usually nothing more than a list of tools and their man pages. If you just want a list of tools, go to LinuxSecurity and look them up yourself. If you are looking for a book that will guide you through hardening your linux machine, the best book out there is undoubtably Hacking exposed Linux.
