White hat refers to a person who uses their skills and knowledge for ethical and lawful purposes, particularly in the field of computer security. This term originated from the concept of a “white hat hacker,” someone who uses their expertise to identify and fix vulnerabilities in computer systems, rather than exploiting them for personal gain. In broader terms, a white hat can also refer to someone who follows moral and ethical standards in their actions and decisions. This term is often contrasted with “black hat,” which refers to those who use their skills for malicious or illegal activities. White hats play a crucial role in maintaining the integrity and security of technology, and their actions are essential in protecting individuals and organizations from cyber threats.
