Ethical Hacking is an authorized practice of bypassing system security to identify potential data breaches and threats in a network. The company that owns the system or network allows Cyber Security experts to perform such activities in order to test the system’s defenses. Thus, unlike malicious hacking, this process is planned, approved, and more importantly, legal.

Ethical hackers aim to investigate the system or network for weak points that malicious hackers can exploit or destroy. They collect and analyze the information to figure out ways to strengthen the security of the system/network/applications. By doing so,  they can improve the security footprint so that it can better withstand attacks or divert them.

Ethical Hackers check for key vulnerabilities include but are not limited to:

  • Injection attacks
  • Changes in security settings
  • Exposure of sensitive data
  • Breach in authentication protocols
  • Components used in the system or network that may be used as access points

There are many free and paid courses are available but here 5 best Ethical hacking Course that gives the mastery on Hacking (Udemy Course):


1. Learn Ethical Hacking from Scratch:



This course is highly practical but it won't neglect the theory; we'll start with ethical hacking basics, breakdown the different penetration testing fields, and install the needed software (on Windows, Linux, and Mac OS X), then we'll dive and start hacking straight away. From here onwards you'll learn everything by example, by analyzing and exploiting different systems such as networks, servers, clients, websites .....etc, so we'll never have any boring dry theoretical lectures.


The course is divided into a number of sections, each section covers a penetration testing/hacking field, in each of these sections you'll first learn how the target system works, the weaknesses of this system, and how to practically exploit theses weaknesses to hack into this system, not only that but you'll also learn how to secure systems from the discussed attacks. By the end of the course, you will have a strong foundation in most hacking or penetration testing fields.

2. Website Hacking / Penetration Testing & Bug Bounty Hunting:



This course is highly practical but it won't neglect the theory, first, you'll learn how to install the needed software (on Windows, Linux, and Mac OS X) and then we'll start with websites basics, the different components that make a website, the technologies used, and then we'll dive into website hacking straight away. From here onwards you'll learn everything by example, by discovering vulnerabilities and exploiting them to hack into websites, so we'll never have any dry boring theoretical lectures.


Before jumping into hacking, you'll first learn how to gather comprehensive information about the target website, then the course is divided into a number of sections, each section covers how to discover, exploit and mitigate a common web application vulnerability, for each vulnerability you will first learn the basic exploitation, then you will learn advanced techniques to bypass security, escalate your privileges, access the database, and even use the hacked websites to hack into other websites on the same server.


All of the vulnerabilities covered here are very common in bug bounty programs, and most of them are part of the OWASP top 10.

3. Network Hacking Continued - Intermediate to Advanced




this course is highly practical, but it will not neglect the theory, since this is an advanced course we will be breaking each attack into its smaller components and understand how each of these components work, therefore by the end of the course you will be able to mix these attacks and adapt them to suit different situations and different scenarios, you will also be able to write your own man in the middle scripts to implement your own attacks.

Because this course builds on what you learn in the courses mentioned above, the main sections here have similar titles to the main sections in these courses, but the topics covered here are more advanced.
