White hat hacking, also known as ethical hacking, is a computer security[1] field with a rich history and diverse practices. It originated in the United States in the early stages of computer[3] development, with the Air Force conducting an evaluation of the Multics operating system. Ethical hacking involves identifying and exploiting system vulnerabilities to reveal potential security[4] threats. This practice extends beyond software attacks and includes methods such as social engineering and physical infiltration. Despite its controversial nature, some countries, like Belgium and China, have recognized and regulated ethical hacking. White hat hackers are highly skilled professionals, proficient in penetration testing, social engineering, and mobile technology[2]. Their expertise is essential for companies to enhance their network security. Several notable figures, resources, and incidents associated with ethical hacking highlight its importance in today’s digital world.

Terms definitions
1. computer security.
1 Computer security, also known as cybersecurity, is a specialized field that involves safeguarding computer systems, networks, and data from digital attacks. These attacks often aim to access, change, or destroy sensitive information, interrupt normal business processes, or exploit system vulnerabilities for malicious purposes. Cybersecurity threats and attacks come in various forms such as malware, phishing, and denial-of-service attacks, among others. To combat these threats, security measures such as access control, firewalls, secure coding, and hardware protection are employed. It's also critical to continuously update these measures, given the evolving nature of cyber threats. The statistics and trends in this field underscore the importance of maintaining robust computer security to prevent potentially costly and damaging breaches.

2. technology. Technology, derived from the Greek words meaning craft and knowledge, is a broad term that refers to the tools, machines, and systems developed by humans to solve problems or fulfill objectives. Originating with primitive tools like stone axes and the discovery of fire, technology has evolved significantly throughout human history. It has been instrumental in different eras, from the invention of the wheel and advanced irrigation systems in ancient civilizations to the birth of universities and printing press during the medieval and Renaissance periods. The Industrial Revolution in the 18th century marked a significant shift in mass production and innovation, giving rise to modern technologies like electricity, automobiles, and digital communication platforms. Today, technology is integral to various aspects of life and society, driving economic growth and societal change, while also raising concerns about security, privacy, and environmental impacts. The future of technology is expected to bring even more advancements, with the rise of artificial intelligence predicted to have significant implications for the job market.

A white hat (or a white-hat hacker, a whitehat) is an ethical security hacker. Ethical hacking is a term meant to imply a broader category than just penetration testing. Under the owner's consent, white-hat hackers aim to identify any vulnerabilities or security issues the current system has. The white hat is contrasted with the black hat, a malicious hacker; this definitional dichotomy comes from Western films, where heroic and antagonistic cowboys might traditionally wear a white and a black hat, respectively. There is a third kind of hacker known as a grey hat who hacks with good intentions but at times without permission.

White-hat hackers may also work in teams called "sneakers and/or hacker clubs", red teams, or tiger teams.
