API Security Best Practices 🐧

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

Protect against injection attacks:

• Validate all input data
• Sanitize user inputs
• Use parameterized queries
• Implement request schema validation
• Prevent SQL injection, XSS, and command injection

Step 3: Rate Limiting & Throttling

Prevent abuse and DDoS attacks:
