Your company’s web application has been suffering from numerous SQL injection attacks. As the security analyst, you recommend implementing a specific technique to the development team to prevent these attacks. Which technique should be implemented to protect against SQL injection vulnerabilities?
To prevent SQL injection attacks, the appropriate method is to use parameterized queries. Parameterized queries ensure that user inputs are treated strictly as data and not as executable code. This distinction prevents attackers from injecting malicious SQL commands into the database query. While other methods, such as input validation and prepared statements, play roles in securing web applications, parameterized queries are specifically designed to address SQL injection vulnerabilities.
