A white hat hacker is an ethical hacker who uses their skills to improve security systems. These hackers use the same techniques as criminals, but instead of exploiting weaknesses, they look for ways to protect networks and systems from malicious activity. White hat hackers use their knowledge of computer systems and networks to identify and fix vulnerabilities. This can include finding and reporting weaknesses in software, operating systems, and networks. They can also provide assistance with penetration testing, which is a form of security assessment that looks for potential vulnerabilities.

White hat hackers are often employed by companies and organizations to test the security of their networks and systems. They can also be hired by individual users to check for vulnerabilities on a personal computer. The goal of white hat hacking is to make sure that systems are secure and protected from malicious activity. This type of hacking is essential for organizations, as their networks and systems are often targeted by malicious actors.

White hat hackers are required to follow a strict code of ethics when conducting their activities. They are not allowed to use their knowledge and skills for malicious purposes, and must take measures to protect the privacy and security of the people, organizations, and systems they are testing. They must also adhere to laws and regulations regarding computer security.
