How is a "white hat hacker" defined?

A "white hat hacker" is defined as an ethical hacker who improves security. This term is commonly used in the cybersecurity field to refer to professionals who use their hacking skills for defensive purposes. White hat hackers work to identify vulnerabilities in systems and networks, allowing organizations to fix security flaws before malicious actors can exploit them. Their activities are typically authorized and conducted with the aim of enhancing security protocols, thus protecting sensitive information and systems from attacks.

In contrast, other terms mentioned pertain to individuals with malicious intent. Those who break into systems for profit or engage in corporate espionage are often classified as "black hat hackers," while criminal hackers who steal data operate outside ethical and legal boundaries. Therefore, the role of a white hat hacker is essential in promoting cybersecurity measures and safeguarding digital environments.
