Step-by-step explanation:
People who test the limitations of information systems out of intellectual curiosity to see whether they can gain access and how far they can go are called ethical hackers or white hat hackers.
Ethical hackers are individuals who use their skills to identify vulnerabilities in computer systems and networks in order to help organizations improve their security. These hackers often work with the consent and knowledge of the system owners and adhere to strict ethical guidelines.
White hat hackers, on the other hand, refer specifically to hackers who are hired by organizations to identify and fix security vulnerabilities. They perform penetration testing, which involves simulating attacks to test the effectiveness of security measures.
