Introduction
Ethical hacking has become one of the most in-demand skills in the cybersecurity industry. Companies around the world hire ethical hackers to identify vulnerabilities in their systems before malicious hackers exploit them.
Many beginners believe that learning ethical hacking requires expensive courses or certifications. However, the reality is different. Today, there are several free platforms and learning resources that allow anyone to start learning cybersecurity and ethical hacking from home.
In this guide, we will explain how to learn ethical hacking for free and eventually start freelancing as a cybersecurity professional.
What is Ethical Hacking?
Ethical hacking refers to the process of legally testing computer systems, networks, and applications to find security vulnerabilities.
Ethical hackers use the same techniques as malicious hackers, but their goal is to improve security rather than exploit it.
Their responsibilities include:
- Identifying security weaknesses
- Testing applications and networks
- Reporting vulnerabilities
- Helping organizations improve their security systems
Because cyber attacks are increasing worldwide, skilled ethical hackers are highly valued in the cybersecurity industry.
Step 1: Learn the Fundamentals of Networking
Before learning hacking techniques, it is essential to understand how computer networks work.
Networking knowledge helps you understand how data travels between systems and how attackers exploit weaknesses.
Important networking concepts include:
- IP addresses
- DNS
- TCP and UDP protocols
- Firewalls
- Network security
A great place to start learning networking fundamentals is the Cisco Networking Academy.
