• What tools should I learn?

• Which certifications are valuable?

• How long does it take to become an ethical hacker?

This roadmap answers these questions and provides a structured path from beginner to professional ethical hacker.

What is Ethical Hacking?

Ethical hacking is the process of legally testing systems, networks, applications, and digital infrastructure to identify vulnerabilities before malicious hackers can exploit them.

Ethical hackers, also known as White Hat Hackers, use the same techniques and tools as attackers but with proper authorization and for defensive purposes.

Their responsibilities include:

• Vulnerability Assessment

• Penetration Testing

• Security Auditing

• Risk Assessment

• Security Monitoring

• Incident Investigation

The goal is simple:

Find security weaknesses before attackers do.
