Introduction
In this blog post, we will explore how to build a secure SQL injection testing page using ASP.NET Web Forms and C#. This project is ideal for learning about basic SQL injection protection mechanisms and implementing input sanitization, error handling, and parameterized queries.
Technologies Used
- ASP.NET Web Forms (ASPX)
- C# (Code-Behind)
- SQL Server
- ADO.NET with SqlHelper (Application Block)
- Bootstrap 5 (Frontend UI)
Goal of This Application
- Provide a login form that is intentionally structured to test SQL injection patterns.
- Detect and block malicious inputs from both query string and form fields.
- Log all suspicious activity.
- Redirect users to a custom error page when SQL injection attempts are detected.
