How can I prevent injection attacks in my web application?

To prevent injection attacks, you should use parameterized queries, validate user input, and employ ORM frameworks.

What are parameterized queries?

Parameterized queries are a way to execute SQL statements where the parameters are bound to the query, preventing malicious input.

Can you give me an example of how to implement them?

Sure! In Python with SQLite, you can use cursor.execute('SELECT * FROM users WHERE id = ?', (user_id,)) to safely include user input.

What other security measures should I consider?

In addition to parameterized queries, consider using input validation, escaping output, and implementing web application firewalls.
