SQL Injection Strategies

By: Ettore Galluccio, Edoardo Caselli, Gabriele Lombari

Overview of this book

SQL injection (SQLi) is probably the most infamous attack that can be unleashed against applications on the internet. SQL Injection Strategies is an end-to-end guide for beginners looking to learn how to perform SQL injection and test the security of web applications, websites, or databases, using both manual and automated techniques. The book serves as both a theoretical and practical guide to take you through the important aspects of SQL injection, both from an attack and a defense perspective. You’ll start with a thorough introduction to SQL injection and its impact on websites and systems. Later, the book features steps to configure a virtual environment, so you can try SQL injection techniques safely on your own computer. These tests can be performed not only on web applications but also on web services and mobile applications that can be used for managing IoT environments. Tools such as sqlmap and others are then covered, helping you understand how to use them effectively to perform SQL injection attacks. By the end of this book, you will be well-versed with SQL injection, from both the attack and defense perspective.

Summary

So, to sum this up, let's take a look at what we covered in this chapter. SQL works using relationships, and it accepts a wide range of commands. We've also seen that, in general, some of these can be abused by malicious attackers. For this reason, we should keep security in mind when designing and developing applications that rely on databases. This chapter gave you a taste of the main security issues and possible solutions.

The next chapter will focus on what a malicious attacker can do by taking advantage of SQL capabilities. We will provide examples of this, all while dealing with aspects related to non-relational databases.

This first chapter, despite being more abstract, is essential for focusing on the main concepts behind SQL injection. Of course, this just an introduction to what we are going to cover throughout this book, but with more concrete examples. Be sure to keep these topics in mind when dealing with the practical aspects of SQL injection.
