Emmett

This book would not exist were it not for Mike Pastore, the author of the first edition. He took a set of convoluted objectives for a broad exam and wrote the foundation of the study guide that you now hold in your hands. While the exam and their associated objectives improved with each iteration, all subsequent editions of this text are forever indebted to his knowledge, hard work, and brilliance so early on.

Thanks are also due to Gary Schwartz, for being one of the best editors in publishing to work with, and to all of those at Wiley who helped with this title.

If youre preparing to take the Security+ exam, youll undoubtedly want to find as much information as you can about computer and physical security. The more information you have at your disposal and the more hands-on experience you gain, the better off youll be when attempting the exam. This study guide was written with that in mind. The goal was to provide enough information to prepare you for the test, but not so much that youll be overloaded with information thats outside the scope of the exam.

This book presents the material at an intermediate technical level. Experience with and knowledge of security concepts, operating systems, and application systems will help you get a full understanding of the challenges that youll face as a security professional.

Weve included review questions at the end of each chapter to give you a taste of what its like to take the exam. If youre already working in the security field, we recommend that you check out these questions first to gauge your level of expertise. You can then use the book mainly to fill in the gaps in your current knowledge. This study guide will help you round out your knowledge base before tackling the exam.

If you can answer 90 percent or more of the review questions correctly for a given chapter, you can feel safe moving on to the next chapter. If youre unable to answer that many correctly, reread the chapter and try the questions again. Your score should improve.

Dont just study the questions and answers! The questions on the actual exam will be different from the practice questions included in this book. The exam is designed to test your knowledge of a concept or objective, so use this book to learn the objectives behind the questions.
