Overview of this book

This book starts with the basics of ethical hacking, how to practice hacking safely and legally, and how to install and interact with Kali Linux and the Linux terminal. You will explore network hacking, where you will see how to test the security of wired and wireless networks. You’ll also learn how to crack the password for any Wi-Fi network (whether it uses WEP, WPA, or WPA2) and spy on the connected devices. Moving on, you will discover how to gain access to remote computer systems using client-side and server-side attacks. You will also get the hang of post-exploitation techniques, including remotely controlling and interacting with the systems that you compromised. Towards the end of the book, you will be able to pick up web application hacking techniques. You'll see how to discover, exploit, and prevent a number of website vulnerabilities, such as XSS and SQL injections. The attacks covered are practical techniques that work against real systems and are purely for educational purposes. At the end of each section, you will learn how to detect, prevent, and secure systems from these attacks.

What is SQL?

We are going to be learning about a popular type of vulnerability called SQLi. Before we discuss how it occurs and how to exploit it, let's first learn what SQL is. For example, if we are performing a pen test on a certain website, the chances are the website is a little bit bigger than other websites and so probably uses a database. Most websites, other than very simple ones use databases to store data, such as usernames, passwords, news articles, blog posts, pictures, and anything that happens on the website. The web application reads the database and then displays the data to us or to the users. When the user performs an action on the website, the application will either update, delete, or modify the data that exists in the database. This interaction between the web application and the database happens using a language called SQL.

Let's see what we mean...
