API Security Checklist

🔑 Authentication & Authorization

• Implement proper authentication & authorization mechanisms #securityUse OAuth 2.0 or JWT for token-based authentication Limit token lifetime and enforce token revocation Require strong, unique passwords for user accounts Implement role-based access control (RBAC) for different user types Use multi-factor authentication (MFA) for critical actions or sensitive data access

⚙️ Validation & Sanitization

• Validate and sanitize all user input to prevent injection attacks #securityUse parameterized queries to prevent SQL injection Utilize input validation libraries to ensure data integrity Sanitize user input to prevent XSS and other injection attacks Reject requests with invalid or missing input data

🔒 Encryption & Secure Communications

• Secure all data transmission with encryption #securityUse HTTPS with strong SSL/TLS configurations Enable HTTP Strict Transport Security (HSTS) Encrypt sensitive data at rest (e.g., API keys, passwords)

🚥 Rate Limiting & Throttling

• Implement rate limiting and throttling to protect against abuse #securityLimit the number of requests per user/IP address Implement progressive delays for repeated failed requests Use CAPTCHAs or other challenge-response tests for suspicious activity

📈 Monitoring & Logging

• Monitor and log all API activity for security incidents #securityImplement centralized logging for all API requests and responses Monitor logs for suspicious activity or unauthorized access attempts Set up automated alerts for potential security incidents Regularly review and audit logs for compliance and security purposes
