What is SQL injection in MVC frameworks?

SQL injection is a code injection technique that exploits vulnerabilities in an application's software by inserting malicious SQL statements into an entry field for execution.

How can I prevent SQL injection in my MVC application?

To prevent SQL injection, use parameterized queries, ORM frameworks, and validate user inputs. Always sanitize and escape inputs.

Can you give me an example of a parameterized query?

Sure! In C#, using Entity Framework, you can write: context.Users.Where(u => u.Username == username).ToList(); This safely handles user input.

What are some common signs of SQL injection attacks?

Common signs include unexpected database errors, slow performance, and unusual database activity. Always monitor logs for anomalies.
