Overview of this book

Security+ certification is the most popular entry-level certification for cybersecurity professionals.

The last two chapters each contain a full-length Security+ practice test that’s designed to assess your readiness to take the actual test. At the end of each chapter, you’ll find the answers to all of the questions along with detailed explanations to help reinforce your learning of the material. By the end of the book, you’ll have enough practice to easily ace the CompTIA Security+ exam.
