What is Ethical Hacking?

Before diving into the “how,” let’s define what ethical hacking actually is. Ethical hacking, also known as penetration testing or white-hat hacking, involves using hacking techniques to identify security vulnerabilities in systems, networks, and applications. The key difference between ethical hacking and malicious hacking is intent. Ethical hackers have permission from the system owner to conduct these tests, with the goal of improving security and preventing real-world attacks. An ethical hacker is essentially a cybersecurity professional who uses their skills for good.

The role of an ethical hacker is crucial in today’s digital landscape. Businesses and organizations are increasingly reliant on technology, making them vulnerable to cyberattacks. Ethical hackers help protect these entities by proactively identifying and mitigating security risks.
