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.

SQL for SQL injection – a recap

This chapter served as an introduction to, in a general sense, the basic topics behind SQL injection. The following is a summary of the main points to focus on in this first chapter so that you can memorize the main concepts we have mentioned thus far:

  • SQL injection is a software weakness of SQL, a specific language and engine for interacting with database structures based on the relational model that treats data in a structured format using tables. It can allow malicious users to execute arbitrary commands, thus interacting with the database of an application in a way that is not originally intended by the application SQL injection can be used by attackers in many ways:
  • SQL provides a simple language that can be used to perform operations on relational databases. SQL processes statements with simple structures in most cases. Some SQL statements are as follows:
