Api Security Best Practices
This walks you through hardening your API endpoints against the usual suspects: injection attacks, auth bypasses, rate limit abuse, and data leaks. You get concrete implementations for JWT authentication with refresh tokens, middleware for token verification, parameterized queries to prevent SQL injection, and rate limiting strategies. The examples are production-ready Node.js code, not just theory. It covers the OWASP API Security Top 10 systematically, which is exactly what you need before a security audit or when reviewing legacy endpoints that were built fast and loose. The input validation section alone could save you from a lot of pain, especially the part about sanitizing error messages so you don't leak database structure to attackers.

API Security Best Practices
Overview
Guide developers in building secure APIs by implementing authentication, authorization, input validation, rate limiting, and protection against common vulnerabilities. This skill covers security patterns for REST, GraphQL, and WebSocket APIs.
When to Use This Skill
- Use when designing new API endpoints
- Use when securing existing APIs
- Use when implementing authentication and authorization
- Use when protecting against API attacks (injection, DDoS, etc.)
- Use when conducting API security reviews
- Use when preparing for security audits
- Use when implementing rate limiting and throttling
- Use when handling sensitive data in APIs
How It Works
Step 1: Authentication & Authorization
I'll help you implement secure authentication:
- Choose authentication method (JWT, OAuth 2.0, API keys)
- Implement token-based authentication
- Set up role-based access control (RBAC)
- Secure session management
- Implement multi-factor authentication (MFA)
Step 2: Input Validation & Sanitization
