Congratulations on your purchase of CompTIA Security+ Practice Tests. This book will serve as a preparation tool for the CompTIA Security+ certification exam (SY0-501) as well as your career in the IT security field.

The objective of this book is to prepare you for the CompTIA Security+ exam by explaining the terminology and technology that will be tested on the exam. The main focus of this book is to help you pass the exam. We dont always cover every aspect of the related field, so some of the aspects of the technology will be covered only to the extent necessary to help you understand what you will need to know to pass the exam. We hope this book will become a valuable resource for you after you achieve the certification.

In a digital world, digital literacy is an essential survival skill. Certification proves that you have the knowledge and skill to solve business problems in virtually any business environment.

Certification makes you more competitive and employable. Research has shown that people who study technology get hired. In the competition for entry-level jobs, applicants with high school diplomas or college degrees who included IT coursework in their academic load consistently fared better in job interviews and were hired in significantly higher numbers. If considered a compulsory part of a technology education, testing for certification can be an invaluable competitive distinction for IT professionals.
