How can I ensure my web application is protected against SQL injection attacks?

Answer

To protect your web application against SQL injection attacks, you should use parameterized queries or prepared statements, which ensure that user input is treated as data rather than executable code.

<!-- BEGIN COPY / PASTE -->
    // Example of using parameterized queries in PHP with PDO
    $stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');
    $stmt->execute(['username' => $userInput]);
    $result = $stmt->fetchAll();
    <!-- END COPY / PASTE -->

Additional Comment:

Always validate and sanitize user inputs even when using prepared statements.
Use ORM libraries that inherently protect against SQL injection by abstracting query building.
Regularly update your database management systems and libraries to patch known vulnerabilities.
