Summary and Info
This book is a decent overview. It is not the book you would use as your primary tool for getting ready for the certification, but it would be a great 'cram week' tool. I am using it as the 'text book' for an overview course I am teaching to a group of teenagers involved in the Cyber Security Challenges. It is a great starting point, then we develop the individual topics with more detailed materials.
Good book if you already have a good understanding of what you are doing and need to focus for the test. Don't try to take the test using this book alone, but it should be in you study library.
