Building functional software is only half the battle; keeping user data secure is the other. With rising cyber threats, securing API endpoints in Laravel or Node.js should never be an afterthought.
API Security Checklist
Implement these essential security controls in your web application backend:
1. Input Validation and Sanitization
Never trust user data. Validate all incoming parameters against strict schemas (e.g. Laravel validation arrays or Node.js Joi/Zod schemas) to prevent SQL Injection and Cross-Site Scripting (XSS).
2. Secure Authentication with JWT or Sanctum
Use robust, token-based authentication. Ensure JWT tokens have short expiration times, are stored securely on the client in HTTP-only cookies, and implement token-revocation patterns.
3. Implement CORS and Rate Limiting
Configure Cross-Origin Resource Sharing (CORS) to only allow requests from whitelisted domains, and apply rate limits (e.g. maximum 100 requests per minute) to defend APIs against DDoS attacks.
