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.

Chapter 1

  1. A database is a way to store data in a permanent way, usually in a structured and accessible way so that its content can be easily queried.
  2. A relational database is a database that uses tables to store data. These tables model objects and the relations among them, as the name suggests.
  3. Structured Query Language (SQL) is a language responsible for interacting with relational databases and relies on building queries with a straightforward syntax.
  4. Some examples of SQL-based systems include MySQL, SQLite, Microsoft SQL Server, and Oracle Database.
  5. SELECT is the most common SQL statement as it's responsible for querying a database to return data based on specified requirements.
  6. SQL injection is an attack that involves inserting, through inputted data, arbitrary SQL commands. This may result in otherwise restricted operations against a database being used by the target application.
