What measures can be implemented to prevent SQL Injection attacks in a web application?

To prevent SQL Injection attacks in a web application, the following measures can be implemented:

1. **Input Validation**: Validate and sanitize all user inputs received from the web application’s forms or other user inputs fields. Use prepared statements or parameterized queries to validate and bind user inputs to prevent malicious SQL code injection.

2. **Use ORM Tools**: Object-Relational Mapping (ORM) tools like Hibernate or Entity Framework can help prevent SQL Injection by abstracting database interactions and automatically parameterizing queries.

3. **Avoid Dynamic SQL**: Avoid the use of dynamic SQL queries as they are more prone to SQL Injection attacks. Instead, prefer using stored procedures or functions to interact with the database.

4. **Least Privilege Principle**: Grant minimum necessary privileges to the database user account used by the web application to limit the potential damage of a successful SQL Injection attack.

5. **Web Application Firewall (WAF)**: Implement a WAF that can detect and prevent SQL Injection attacks by filtering HTTP traffic and blocking malicious requests.

6. **Regular Security Audits**: Conduct regular security audits and penetration testing to identify and remediate any vulnerabilities in the web application that could be exploited by SQL Injection attacks.

By implementing these measures, a web application can significantly reduce the risk of becoming a victim of SQL Injection attacks and enhance its overall security posture.
