# Welcome

This book serves as a comprehensive introduction to penetration testing, designed to equip beginners with the foundational knowledge and skills needed to get started in cybersecurity. Best of all, this handbook is completely free, making it accessible to anyone eager to learn.

While there are many paid courses available, we at **NCA\@Nepal** believe that financial barriers should not prevent aspiring ethical hackers from learning. That’s why we created this book—to provide a free, comprehensive resource covering all the essential topics in penetration testing. Our goal is to equip you with the knowledge and skills needed to enter the field without financial constraints.

Consume the resource ethically, and make sure to check the table of contents to see what we have covered so far.
