SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires bcrypt, express-rate-limit, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps developers implement secure API design patterns, including authentication, authorization, input validation, rate limiting, and protection against common API vulnerabilities, to build robust and secure APIs.

Core Features & Use Cases

  • Authentication and Authorization: Implement secure authentication methods like JWT, OAuth 2.0, and API keys, along with role-based access control and multi-factor authentication.
  • Input Validation and Sanitization: Protect against injection attacks by validating and sanitizing user inputs, using parameterized queries, and implementing request schema validation.
  • Rate Limiting and Throttling: Prevent abuse and DDoS attacks by implementing rate limiting per user/IP and API throttling.
  • Data Protection: Secure sensitive data by encrypting data in transit and at rest, and implementing proper error handling.
  • API Security Testing: Verify security implementation through penetration testing and checking for common vulnerabilities.

Quick Start

Use the api-security-best-practices skill to implement JWT authentication in your API.

FAQPage Schema
How do I implement JWT authentication and role-based access control in my API?

Implement JWT authentication by issuing signed tokens during login and applying role-based access control middleware to verify user permissions before processing requests. This approach secures endpoints by validating token integrity and restricting access based on assigned user roles.

What is the best way to prevent injection attacks through API input validation?

Prevent injection attacks by validating and sanitizing all user inputs, enforcing strict request schema validation, and using parameterized queries. This approach ensures input data conforms to expected formats and prevents malicious code from executing within your API.

How does express-rate-limit work for preventing API abuse and DDoS attacks?

Express-rate-limit prevents API abuse and DDoS attacks by tracking incoming requests per IP or user and blocking traffic that exceeds defined thresholds. This rate limiting middleware restricts excessive requests, protecting backend resources from being overwhelmed.

Can I use bcrypt for password hashing in my API authentication workflow?

Yes, you can use bcrypt for password hashing in your API authentication workflow. Bcrypt securely hashes and salts user passwords before storage, protecting sensitive credentials by ensuring that even if data is compromised, the original passwords remain extremely difficult to reverse engineer.

What are the limitations of relying solely on API keys for authorization?

Relying solely on API keys for authorization limits granular access control, as keys typically grant broad system access rather than specific role-based permissions. This approach lacks multi-factor authentication and exposes APIs to broader vulnerabilities if keys are leaked.
