White hat hacking, also known as ethical hacking, is the practice of using advanced computer skills and techniques to identify and fix security vulnerabilities in computer systems and networks. Unlike black hat hackers, who use their skills for malicious purposes, white hat hackers work with the permission of the system owner to improve security and protect against potential cyber attacks. This type of hacking is often used by companies and organizations to test the strength of their systems and ensure that sensitive information is kept safe from cyber criminals. White hat hackers are highly skilled and knowledgeable individuals who use their expertise for the greater good, making the digital world a safer place for all.
