Ethical Hacking: What is it and Why is it Important?.

Introduction. Definition of ethical hacking Importance of ethical hacking in maintaining cyber security Ethical hacking, also known as "white hat" hacking, is the practice of using hacking techniques to identify and protect against cyber threats. It involves simulating the actions of a malicious hacker in order to test the security of a system or network, and to identify and fix any vulnerabilities before they can be exploited. Ethical hacking is important because it helps to keep our systems and networks secure. With the increasing reliance on technology and the internet in our daily lives, it's more important than ever to ensure that our systems and data are protected against cyber threats. Ethical hackers play a crucial role in identifying and mitigating these threats, and in helping to prevent cyber attacks and data breaches.
