Input Sanitization vs Validation: Protecting Your API From Injection

1. 1Implement input validation using schema-based validation tools like Joi or Zod to ensure data conforms to expected formats
2. 2Use input sanitization techniques like trimming and normalizing user input to prevent XSS attacks
3. 3Configure a Web Application Firewall (WAF) to detect and prevent common web attacks
4. 4Test your API's input handling using tools like OWASP ZAP or Burp Suite to identify vulnerabilities
5. 5Apply least privilege principles to limit damage in case of a successful injection attack

Backend developers and security teams can benefit from understanding the distinction between input sanitization and validation to strengthen their API's defense against malicious attacks

💡 Input validation ensures data correctness, while input sanitization removes harmful characters to prevent injection attacks
