What is Ethical Hacking?
Ethical hacking, or white-hat hacking, is the authorized process of discovering vulnerabilities in systems, networks, or applications — all within legal boundaries. In today's cyber age, companies rely on ethical hackers to identify flaws before malicious hackers can.
Unlike cybercriminals (black-hats), ethical hackers act with permission and follow a professional code of conduct. The practice includes:
-
Testing networks and apps for flaws
-
Reporting vulnerabilities to organizations
-
Enhancing overall system security
✅ Ethical hackers protect digital systems, support cybersecurity resilience, and earn money through bug bounty programs or security jobs.
Why Tool Setup Matters for Beginners
Before you jump into scanning and exploiting, it’s crucial to have your penetration testing environment ready. A well-structured tool setup ensures:
-
✅ Legal & safe practice
-
✅ Realistic hands-on learning
-
✅ Mastery of ethical hacking workflows
-
✅ Easy transition to real-world jobs
