A Hacker is a person with advanced technical skills who finds and exploits vulnerabilities in computer system and networks, often to gain unauthorized access.

                Types of Hacker

There are basically three types of hackers: white hat hackers, who protect systems by finding and fixing security flaws; black hat hackers, who steal or damage data by exploiting vulnerabilities with malicious intent; and grey hat hackers, who break into systems without permission to discover vulnerabilities, but intentions are not always malicious.

        White Hat Hacker (Ethical Hacker)

 These are hackers who work for companies or organizations and with their permission, find security vulnerabilities in systems and networks.

 "Their purpose is to make the system secure, so that black hat hackers cannot take advantage of it". 

        Black Hat Hacker (Malicious Hacker) 

 These hackers intrude into the system for illegal and malicious purposes. "Their motive is personal gain, financial advantage, or causing harm to others' data and systems. These are also called crackers". 

            Gray Hat Hacker

 These hackers fall in the category between white hat and black hat. They find vulnerabilities in the system, but often they do not have the permission to do so.Their intentions may not be entirely malicious, but their activities are not legal because they enter the systemwithout permission
