Common Ways to Prevent SQL Injection Attacks in Web Applications

1. Use Parameterized Queries: Parameterized queries can help prevent SQL injection attacks by utilizing placeholders for user input.
2. Input Validation: Validate and sanitize user input to ensure that only expected and safe data is passed to the database.
3. Escaping User Input: Escape special characters in user input before executing the SQL query to prevent injection attacks.
4. Implement Least Privilege: Limit the database user's privileges to only necessary operations to reduce the impact of potential attacks.
5. Use Stored Procedures: Store SQL logic within database stored procedures, reducing the risk of injection attacks.
6. Web Application Firewall: Implement a web application firewall to monitor and filter out potential SQL injection attempts.
