This book takes a hands-on approach to teaching and understanding penetration testing concepts at an intermediate to advanced level. It's designed to lay the foundation for advanced roles in the field with an engaging and easy-to-follow style. There are a lot of books on the subject of penetration testing, but what makes this book special is the emphasis on the underlying logic and mechanisms of the concept at hand. Recognizing that there aren't enough pages to give each subject what it deserves, this book takes a springboard approach to the topics by providing enough key information and theory to inform further research outside of these pages. The reader can thus spend less time searching and more time learning.
