I have been at work for the past few weeks, and I have gotten through the first few chapters (Page 151 to be exact) of my Official (ISC)2 Guide to the CISSP CBK. These chapters are about Security and Risk Management, which is domain 1 of the 8 domains in CISSP.
The first topic it talked about was the CIA triad. CIA stands for Confidentiality, integrity, and Accessibility, These three are rather self explanatory but are very important and will be used later, so its important to know about them. After the CIA triad it went to Security Governance, this was more complex, but it basically was talking about what someone in the role of a CISSP and what their role and responsibilities are when it comes to the Governance of security. Over all the content of the book isn't hard to understand, and I believe that anyone with dedication will be able to read, and understand its content. I still have much more to learn from it though, as I have only made it to page 151 out of over 1000 pages. Reading is an essential skill for this program!
