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 computador[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 tecnologia[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.

Definições de termos
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. tecnologia. A tecnologia, derivada das palavras gregas que significam ofício e conhecimento, é um termo amplo que se refere às ferramentas, máquinas e sistemas desenvolvidos pelo homem para resolver problemas ou cumprir objectivos. Com origem em ferramentas primitivas como os machados de pedra e a descoberta do fogo, a tecnologia evoluiu significativamente ao longo da história da humanidade. Foi fundamental em diferentes épocas, desde a invenção da roda e dos sistemas avançados de irrigação nas civilizações antigas até ao nascimento das universidades e da imprensa durante os períodos medieval e renascentista. A Revolução Industrial, no século XVIII, marcou uma mudança significativa na produção em massa e na inovação, dando origem a tecnologias modernas como a eletricidade, os automóveis e as plataformas de comunicação digital. Hoje em dia, a tecnologia faz parte integrante de vários aspectos da vida e da sociedade, impulsionando o crescimento económico e a mudança social, ao mesmo tempo que suscita preocupações sobre a segurança, a privacidade e os impactos ambientais. Espera-se que o futuro da tecnologia traga ainda mais avanços, prevendo-se que o aumento da inteligência artificial tenha implicações significativas no mercado de trabalho.

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, em que 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, ou tiger teams.
