How to become a ethical hacker for beginners for free

Becoming an ethical hacker (also known as a white-hat hacker) is an exciting journey that involves a combination of knowledge, skills, and hands-on experience. Ethical hackers use their skills to identify and fix security vulnerabilities in systems, networks, and software. Here’s a step-by-step guide for beginners on how to get started:

1. Understand What Ethical Hacking Is

Ethical hacking involves finding vulnerabilities in systems to help organizations improve their security. Unlike black-hat hackers (who engage in illegal activities), ethical hackers have permission to test the systems and report vulnerabilities to the relevant parties.

2. Learn the Basics of Computer Networking

A strong understanding of how computer networks work is crucial for ethical hackers. Some key topics to study include:

• TCP/IP protocols (Transmission Control Protocol/Internet Protocol)
• Subnetting and IP addressing
• DNS (Domain Name System)
• HTTP/HTTPS, FTP, and other protocols used in networking
• Network devices (routers, switches, firewalls)

Recommended resources:

• CompTIA Network+ certification
• Books: “Network Warrior” by Gary A. Donahue

3. Get Comfortable with Operating Systems

Understanding operating systems is essential, especially Linux. Many ethical hacking tools are designed for Linux, and the command line interface (CLI) is widely used in hacking.

• Linux: Learn how to use Linux distributions like Kali Linux, Parrot Security OS, or Ubuntu. Kali Linux, in particular, is a popular choice among ethical hackers because it comes with pre-installed security tools.
• Windows: Many businesses use Windows, so understanding how to navigate and secure it is also important.

Recommended resources:

• “Linux Basics for Hackers” by OccupyTheWeb
• Practice using Linux commands on your own machine or in a virtual environment.

4. Learn Programming and Scripting

A good ethical hacker should be able to write code, automate tasks, and understand how programs are developed. While you don’t need to be a master developer, knowing how to read and write basic code will help in identifying vulnerabilities and creating your own hacking scripts.

• Languages to learn:
  • Python: Great for writing scripts and automation.
  • JavaScript: Useful for understanding web vulnerabilities like cross-site scripting (XSS).
  • C/C++: Important for understanding low-level programming and buffer overflows.
  • Bash and PowerShell: Used for automating tasks in Linux and Windows.

Recommended resources:

• Codecademy, freeCodeCamp, or other online coding platforms
• Books: “Python for Everybody” by Charles Severance

5. Understand Cybersecurity Concepts

Learn about the basics of cybersecurity and how attackers exploit vulnerabilities. Some concepts to focus on include:

• Common vulnerabilities (SQL injection, cross-site scripting, etc.)
• Malware and viruses
• Encryption and cryptography
• Firewalls, VPNs, and proxies
• Incident response and forensics

Recommended resources:

• CompTIA Security+ certification
• Websites like OWASP (Open Web Application Security Project) and Cybrary

6. Get Hands-On Experience

Theory is important, but practical experience is key. You can practice ethical hacking in a safe, legal environment using these methods:

• Capture the Flag (CTF) challenges: These are online competitions where you solve security challenges to find hidden flags.
  • Websites like Hack The Box, TryHackMe, and OverTheWire offer a hands-on way to practice your skills in legal environments.
• Create your own lab: Set up a virtual machine environment using tools like VirtualBox or VMware. You can use tools like Kali Linux for penetration testing, or try setting up vulnerable systems like DVWA (Damn Vulnerable Web Application) for practice.
• Bug bounty programs: Once you feel confident, try joining platforms like HackerOne or Bugcrowd to test your skills by finding bugs in real-world applications.

7. Get Certified

Earning certifications will validate your skills and make you more attractive to employers. Some popular certifications for ethical hackers include:

• Certified Ethical Hacker (CEH) by EC-Council: One of the most recognized certifications for ethical hackers.
• CompTIA Security+: Covers fundamental cybersecurity concepts.
• Offensive Security Certified Professional (OSCP): More advanced, hands-on certification focused on penetration testing.

8. Stay Up to Date with Trends and Tools

The world of hacking and cybersecurity is constantly evolving. It’s important to keep learning about new vulnerabilities, attack techniques, and security tools. Some good ways to stay informed:

• Follow blogs like Krebs on Security or Dark Reading
• Join forums like r/netsec or r/AskNetsec on Reddit
• Attend webinars, conferences, and workshops (many are online and free)
• Follow ethical hackers on Twitter and other social media platforms

9. Develop an Ethical Mindset

As an ethical hacker, you must always work with integrity. Your goal is to improve security, not exploit vulnerabilities for malicious purposes. Always obtain permission before testing systems, and adhere to the legal and ethical guidelines of the industry.

10. Start Applying for Jobs or Freelance Opportunities

Once you have the skills, certifications, and experience, you can start applying for ethical hacking jobs. Many organizations hire ethical hackers as part of their penetration testing teams. You can also consider freelance opportunities where companies or individuals pay for vulnerability assessments.

Becoming an ethical hacker requires dedication, a strong understanding of computer networks, security protocols, and programming. While it can be challenging, it is an incredibly rewarding field with high demand for skilled professionals. By building your knowledge and gaining practical experience, you can move from a beginner to a certified and ethical hacker over time.
