When you take a look at the table of contents, you may see that the booklet covers all the necessary knowledge that a person should know in order to take the certification exam. Contents include:
Lesson 1, about Asymmetric Algorithms, shows the basic concepts and protocols in a clear language. Labs make use of GNU software as Linux and Backtrack. Also, Windows will be necessary: it is important to get to know several OS because security involves multivendor environments.
Lesson 2 covers Steganography, I think it is a good briefing about this subject. Anyway, I would suggest further reading to the hungry minds that would like to get a deeper understanding about this. Nonetheless, the exposed material is clear and deep enough for the exam purposes. I must confess steganography lab is very fun.
Lesson 3 is about Sniffers and protocol analysers. I believe, according to my experience, that this is a very important skill to develop if you work in a security-related business. This lesson shows the most popular programs and its usage.
Lesson 4 teaches about PKI and certificates. This section is very illustrative, because in the lab activity you can practice the concepts and create your own CA and do several operations with it.
Leson 5 shows TCP/IP. Briefly explains the OSI & TCP/IP model, how encapsulation works, three-way-handshake, ports and IPv6. The language used is very clear and understandable. Lab activities are great and lets the reader have a deeper understanding of the concepts exposed in the pdf.
Lesson 6 is about passwords: types, policies & management, attacks and mistakes that we do about them. It is an interesting reading because you have to deal with passwords everyday, you will notice that the password that you use for your e-mail account is not the safest and does not convey with the basic requirements a password should meet. Lab activities help a lot with this.
As a summary, I would like to recommend this product. I think this would be very helpful if you wish to learn and pass the certification exam. I liked it very much because it shows concepts and labs are comprehensive and helps you to increase your knowledge.
