An ethical hacker is one who mimics the actions of a malicious hacker so as to detect security risks in advance and thus prevent breaches and attacks. Ethical hackers play the role of protectors by fending off attacks after attacks, protecting businesses, securing data etc. The need for companies to secure their systems, networks and data with the help of ethical hackers too is increasing. The importance of ethical hacking has increased in todays scenario, when more and more companies are being targeted by cybercriminals.”]
