This book is for security professionals and enthusiasts who want to deepen their knowledge of the web penetration testing world. Many topics will be covered in this book, but you will need the basics of ethical hacking before you start reading (many online courses out there will get you up to speed). If you're a professional, I'm betting that you will appreciate a lot the straight forward checklists that I will provide. In fact, I use them myself in my career as a penetration tester.
