CISSP Certification.
2010/6/17
形式:ペーパーバック
I picked up this book when I was studying for my CISSP exam and it was a great addition to my study resources. I like the way the book is set up by categories making it very easy to follow along with. The practice quizzes are short which makes them easy to fit into a busy schedule and the answers are detailed enough to clear up any confusion you may have. I would recommend this book to anyone who is preparing to take their CISSP exam.

Good... but...

No disrespect to the other reviewers, but they come off sounding a little fake. This book is good, but not great. I've taken several practice exams from this book and have two main complaints
(1) Several practice questions appear to be unrelated to the CISSP exam.
(2) For several practice questions, I disagreed with their answer; though, for these types of exams -- this is not uncommon. My big complaint: they don't cite any other sources to corroborate their own answer. I've seen a few testing products that provide references to 3rd party material.
Still, a good resource for the price.

Rife with errors

形式:Kindle版|Amazonが確認した購入
I went through the first mock exam and was wholly disappointed at the quality of the book. For example,
15. Which of the following proxy does not operate at the networking layer of the OSI model?
A. Stateful proxy
B. Packet filtering
C. Circuit-level proxy
D. Kernel proxy
The given answer is D but a circuit-level proxy is supposed to work at the session layer, i.e., both circuit-level proxy and kernel proxy do not work at the network layer. Furthermore, there's no such thing as "networking layer", but "network layer". It reads almost as if the book wasn't written by a professional.
38. Which of the following is a simple method used in symmetric key cryptography to ensure message integrity?
A. Message digest
B. Diffie-Hellman algorithm
C. Checksums
D. HAVAL
The given answer is C but checksum is not even a cryptographic algorithm! 2 errors in the first 40 questions, that's not very convincing at all. There are more:
CISSP Mock Exam (LITE) - 3
1. Which of the following uses asynchronous encryption?
"Asynchronous encryption" should actually be "asymmetric-key encryption".
10. In the context of cryptography, which of the following is incorrect?
The given answer is "D. A message can be encrypted and this provides integrity." This is wrong, because a cipher can be used as an inefficient message authentication code, and this does provide integrity. The answer should actually be "B. A message can be hashed and this provides integrity." An attacker can replace the message and the hash together, thereby violating integrity, hence the answer should be B! The author(s) seem to be hopelessly unknowledgeable in cryptography.
CISSP Mock Exam (LITE) - 5
5. What type of interference can be caused by fluorescent lights that are commonly found in office buildings?
The given answer is "C. Radio frequency interference", but the answer is also "B. Electromagnetic interference", because RFI and EMI are the same.
Lastly, these are comments not related to the correctness of the answers There are too many redundant questions on fibre optics and its security. It seems to me that the authors have simply lifted a statement from Harris' book without a clue of what it really means.
