Ethical hacking, also known as penetration testing or white-hat hacking, is the practice of intentionally penetrating computer systems, networks, or applications with permission from the owner, to identify security vulnerabilities and weaknesses. The goal of ethical hacking is to improve the security posture of the target system by uncovering potential threats before malicious hackers can exploit them. Ethical hackers use the same techniques and tools as malicious hackers, but they do so in a lawful and responsible manner, adhering to strict ethical guidelines and obtaining proper authorization before conducting any tests. Once vulnerabilities are identified, ethical hackers provide recommendations and solutions to help organizations strengthen their defenses and protect against cyber threats. Ethical hacking plays a crucial role in ensuring the security and integrity of digital assets in an increasingly interconnected world.
