Ethical hacking is significant in protecting networks as it involves simulating cyber attacks to identify vulnerabilities before malicious hackers can exploit them. Ethical hackers use the same techniques as cybercriminals but aim to strengthen security rather than compromise it. By conducting regular penetration testing and vulnerability assessments, organizations can fortify their defenses against data breaches, ensuring the integrity of sensitive information. Furthermore, ethical hacking contributes to compliance with regulatory requirements, enhancing the overall cybersecurity posture of organizations.
