What Is a White Hat Hacker? The Ethical Side of Hacking

The term white hat refers to an ethical hacker whose job involves hacking into computer systems to detect security risks. The term and its definition derive from old movie westerns, where law-abiding heroes typically wore white hats. Unlike those who break into computers to destroy or steal data, white hat hackers have good intentions.
