 What is Hacking?

Gaining access to a system that you are not supposed to have access is considered as hacking.

In 1960, the first known event of hacking had taken place at MIT and at the same time, the term Hacker was organized.

What is Ethical hacking?

Ethical hacking is also known as White hat Hacking or Penetration Testing. Ethical hacking involves an authorized attempt to gain unauthorized access to a computer system or data. Ethical hacking is used to improve the security of the systems and networks by fixing the vulnerability found while testing. 

Ethical hackers improve the security posture of

an organization. Ethical hackers use the same

tools, tricks, and techniques that malicious

hackers used, but with the permission of the

authorized person. The purpose of ethical

hacking is to improve the security and to

defend the systems from attacks by malicious

users.
