I’ve been spending an exhausting three months studying for my CISSP exam. I’ve used a variety of sources, but in case anyone is interested here are the most useful ones I’ve read:
1. Official ISC2 Guide to the CISSP CBK (2010 Edition)
2. CISSP for Dummies
3. CISSP study Guide by Sybex
Also, the practice questions by cccure.org are quite good. The link is here:
https://www.freepracticetests.org/quiz/index.php#
As always when studying, I write notes of questions I find difficult, or concepts that I need to clarify to myself. They are highly disjointed, and they’re more like placeholders to remember specific points right before the exam, but someone may find them useful:
