Scenario: Your application uses parameterized queries, but you suspect it may still be vulnerable to SQL injection. What steps would you take to assess and improve its security?
- Implement input validation
- Perform code review to identify vulnerabilities
- Update database permissions
- Use a vulnerability scanner
Conducting a thorough code review can help identify any overlooked vulnerabilities in the application's usage of parameterized queries. Implementing input validation can supplement parameterized queries by ensuring that only expected data formats are accepted. While vulnerability scanners can be useful, they might not catch all potential issues. Updating database permissions can help limit the impact of successful attacks but does not directly address the vulnerability.
