Learn Ethical Hacking from Scratch | A Comprehensive Guide

Ethical hacking, also known as white-hat hacking or penetration testing, is the practice of identifying and exploiting vulnerabilities in computer systems and networks for the purpose of improving their security. With the increasing reliance on technology in every aspect of our lives, the need for skilled and ethical hackers has never been greater. This comprehensive guide will provide you with everything you need to know to learn ethical hacking from scratch.

Part 1: Understanding Ethical Hacking

In this section, we will explore what ethical hacking is, the difference between ethical hacking and illegal hacking, and the importance of ethical hacking in today's world.

Ethical hacking is the practice of using hacking techniques for the purpose of identifying and fixing security vulnerabilities in computer systems and networks. The goal of ethical hacking is to improve security, not to cause harm or steal information. Ethical hackers are professionals who are hired by organizations to test their systems and networks for vulnerabilities.

It's important to understand the difference between ethical hacking and illegal hacking. Illegal hacking, also known as black-hat hacking, is the use of hacking techniques for malicious purposes, such as stealing information or causing damage to computer systems. Ethical hacking, on the other hand, is done with the permission of the organization being tested and is focused on improving security.

The importance of ethical hacking cannot be overstated. With the increasing reliance on technology in every aspect of our lives, the potential for cyber attacks has never been greater. Ethical hackers play a critical role in identifying and fixing vulnerabilities before they can be exploited by malicious hackers.
