The book begins with an introduction to ethical hacking concepts and then demonstrates hands-on the steps necessary to execute specific attacks. Early attacks covered in the book are simple and engaging; designed to give readers the skills necessary to tackle more advanced exploits. The book's emphasis on ethical or white hat hacking demonstrates the importance of balancing security against convenience; in other words, sometimes it can be hard to stay safe on a computer. Readers learn how to avoid phishing, viruses, and ransomware as well as how attackers steal passwords on saved websites or gain access to a computer and its files without a username or password.
