API Rate Limiting and Security Enhancement

[Xaxxoo]

Implement comprehensive API security measures including rate limiting and abuse prevention.

Tasks:
Set up API rate limiting with tiered limits for different endpoints
Implement API key management and authentication system
Create API request logging and monitoring system
Set up API abuse detection and automatic blocking
Implement API request validation and sanitization
Create API security headers and CORS configuration
Set up API documentation with security guidelines
Implement API versioning and deprecation management
Create API testing and security audit tools
Set up API performance monitoring and optimization

Acceptance Criteria:
API is protected against common security vulnerabilities
Rate limiting prevents abuse while allowing legitimate usage
API performance remains optimal under various load conditions
Security measures are transparent and well-documented
API monitoring provides insights for continuous improvement

Hello, I'm Jefferson, a backend engineer based in Cameroon specializing in secure and scalable API design. My stack includes NestJS, TypeScript, Node.js, PostgreSQL, and Redis, with hands-on experience implementing API rate limiting, abuse detection, and audit logging.

For this task, I will implement Redis-backed rate limiting with tiered rules per endpoint type, set up API key-based authentication, and apply request validation and sanitization across all routes. I’ll configure CORS and Helmet for secure headers, log and monitor API traffic, and introduce versioning and deprecation mechanisms. Security documentation and testing tools will be included to ensure the system remains auditable and resilient.

Estimated completion time: 36 hours
