Free Chapter
In this book, you will learn how to become an ethical hacker from scratch. We'll assume that you have no experience in ethical hacking, and, by the end of the book, you will be at an intermediate (to high) level.
Here is a quick overview of what will be covered in this book:
In the first part of this book, you will learn how to create your own lab, so that you can practice ethical hacking on your own computer. You will also learn the installation of Linux systems and how to interact with them, as well as how to set up other systems to try to hack into them.
In this part of the book, we will cover the most important penetration testing fields. In each of these sections, we will first illustrate how a particular system works, and will then test the security of that system. In the following sections, we will introduce the types of penetration testing that will be seen in this book.
In network penetration testing, the first things that we will learn are how networks work and how devices interact with each other.
First, we will learn more about the networks around us; we will gradually proceed by setting up a fake access point and luring people into connecting to networks so that we can capture data that is sent or received through them. We will then learn how to get the password for any Wi-Fi network, whether it uses WEP, WPA, or WPA2 encryption.
We will also go over a large number of powerful attacks that will allow us to gain access to any account that is accessed from any computer in a network. We will be able to capture usernames, passwords, images, and pictures that computers on a network send or receive.
In this part of the chapter, we will learn how to gain access to computer systems. There are two methods to hack a computer:
When learning about server-side attacks, you will see how to discover weaknesses in the programs installed on the target computer, and how to use those weaknesses to gain full access to the computer.
In the client-side attacks, you're going to learn how to use social engineering to hack into the target, you'll learn how to create undetectable backdoors, backdoors that look like images and pictures, and so on. We will also learn how to gain access to any computer if that computer exists in our network by using fake updates or by using fake downloads.
In this section, we look at post exploitation, learning how to control the devices that we hacked. So, we're going to see how to open a system's webcam, manage its filesystems, and download or upload files to it. We will also learn how to capture all of the key strikes that the person enters on their keyboard, or even use that computer as a pivot to hack into other computers.
In the final sections, which will be about website penetration testing, we will learn how to gather very comprehensive information about websites, including how to discover, exploit, and mitigate a large number of serious vulnerabilities.
Finally, we will learn how to protect ourselves (and our systems) from the attacks discussed in the preceding sections.
