🛡️ What is Ethical Hacking?
Ethical hacking (or penetration testing) is the legal practice of testing digital assets to find security weaknesses. Unlike black-hat hackers who exploit vulnerabilities maliciously, white-hat hackers like you document and report findings to system owners.
White-Hat vs Black-Hat: The Critical Difference
White-Hat Hackers:
- Work with explicit permission
- Document all findings
- Follow strict codes of conduct
- Strengthen security systems
Black-Hat Hackers:
- Operate without authorization
- Exploit vulnerabilities for personal gain
- Cause financial/system damage
- Face serious legal consequences
Always obtain written permission before testing any system. Unauthorized access is illegal worldwide, even with "good intentions."
