The latest CCSP Study Guide can be found on Amazon, as well as if you're an ISC2 member, you can order at a discount from the publisher. The current version is the 2nd edition.
CBK is Common Body of Knowledge. A CBK is created (or should be created) for ALL certifications. Its the basis for what your are being tested against and is the basis for how questions are developed and training and other study materials is being developed against.
Some feel that studying the CBK is an important part of any certification study program.
The Study Guide is separate from the CBK. You can obtain the CCSP CBK as a separate work from the Study Guide.
Currently, ISC2 makes available the CBK, Study Guide, and Practice Exams thru Sybex (part of Wiley). All three are in their second editions.
