SQL injection attacks are one of the most common web application security threat and one of the easiest to prevent. Web application attackers will surely test your web application for this security vulnerability so you must take steps to ensure that this security hole is plugged, and plugged fast!

SQL injection attacks are made possible by allowing non-escaped single or double quote strings to be included in your database's SQL call. This can be done very easily by an attacker by including a partial SQL statement in a form field on your application, such as your login screen, where if the included text is constructed just right, could be used to change the return results of the back-end query that is called during that operation. In our login form example, one could easily see how that might result in the ability of an attacker logging into your web application without knowing a password. This is just one of many examples and risks of not handling this SQL injection exploit.

In this step-by-step tutorial, you'll learn how you can prevent SQL injection via Python. You'll learn how to compose SQL queries with parameters, as well as how to safely execute those queries in your database to keep your application and data secure.
