Scenario: A developer is tasked with fixing a SQL injection vulnerability in an application. What steps should the developer follow to address this issue and prevent future vulnerabilities?
- Encrypt all database communications to prevent interception and tampering of sensitive data.
- Implement access controls to restrict database permissions for each user role to minimize the impact of potential attacks.
- Replace all SQL queries with NoSQL queries to eliminate the risk of SQL injection entirely.
- Validate and sanitize all user inputs to prevent malicious SQL queries from being executed.
The developer should follow the best practice of validating and sanitizing all user inputs to prevent SQL injection. This involves using parameterized queries or ORM libraries to ensure that user input is treated as data rather than executable code. Additionally, input validation should be enforced on both the client and server sides to mitigate the risk of injection attacks. Educating developers on secure coding practices and conducting regular code reviews can further enhance the application's resilience to SQL injection vulnerabilities.
