Introduction
SQL Injection (SQLi) is one of the oldest and most dangerous vulnerabilities in web development. It occurs when malicious SQL statements are injected into entry fields for execution, exposing database records.
Best Practices for SQLi Prevention
1. Use Prepared Statements: Parametrized queries ensure database engines treat inputs as data, never as executable code.
2. Adopt Secure ORMs: Object-Relational Mappers (like Eloquent or Hibernate) handle query parameterization automatically.
3. Sanitize and Validate Input: Enforce strict allow-lists on the types of characters accepted in form fields.
Conclusion
SQL injection is entirely preventable. By adopting secure coding practices and database frameworks, you can keep your records safe from malicious access.
