Introduction to Ethical Hacking

Ethical hacking, also known as white-hat hacking or penetration testing, involves legally probing systems, networks, and applications to uncover vulnerabilities before malicious hackers exploit them. Unlike black-hat hackers, who operate with harmful intent, ethical hackers work with permission to enhance security, protect sensitive data, and fortify digital defenses. Their contributions have been instrumental in shaping modern cybersecurity practices, from developing secure software to advocating for responsible vulnerability disclosure. At Cyber Security Training Institute, our training programs empower aspiring ethical hackers with the skills to combat cyber threats effectively.

Criteria for Selection

Selecting the top 10 ethical hackers of all time required evaluating their impact on cybersecurity, contributions to the community, and recognition in the field. The criteria include:

• Innovative Contributions: Development of tools, methodologies, or frameworks that advanced cybersecurity.
• Industry Impact: Influence on security practices, policies, or standards.
• Community Engagement: Contributions through education, mentorship, or advocacy.
