Ethical hacking is an information security branch and called as “Penetration testing” or “White Hat hacking”. They are waged professionals. To overcome the risk of being hacked by hackers, we have ethical hacker in this field, which are specialized in computer security that violates and find loopholes in protected networks or computer systems of some organizations or companies and corrects them to improve security working under set of rules and regulations by various organizations. These are the people who try to protect data while on the internet with various attacks from hackers and keep it safe with the owner. Ethical hackers use the same approaches as black hat hackers, but their intention is to use their knowledge productively. Information obtained from ethical hacking is used to maintain the security of the system and to prevent system from further potential attacks.
