Introduction
Penetration testing, or pentesting, is the practice of testing a computer system, network, or web application to find security vulnerabilities that an attacker could exploit. This guide will walk you through the essential steps to begin your journey.
Step 1: Learn the Fundamentals
Before diving into tools, you need a strong foundation in networking (TCP/IP, DNS, HTTP), operating systems (Linux is essential), and programming basics (Python, Bash).
Step 2: Set Up Your Lab
Install Kali Linux or Parrot OS in a VM. Set up vulnerable machines like Metasploitable, DVWA, or use platforms like HackTheBox and TryHackMe.
Step 3: Essential Tools
- Nmap - Network scanning
- Metasploit - Exploitation framework
- Burp Suite - Web app testing
- Wireshark - Packet analysis
Conclusion
The path to becoming a penetration tester is long but rewarding. Stay consistent, practice ethically, and always keep learning.
