API Security Enhancement – Rate Limiting Implementation Summary

Implemented a global rate-limiting mechanism across all public-facing API endpoints to improve system resilience, protect backend resources, and mitigate abuse vectors such as brute-force attacks, scraping, and denial-of-service attempts.

Completed Work

• Integrated express-rate-limit middleware across the entire HTTP API surface to enforce consistent request throttling for all public endpoints.

• Defined and enforced tiered rate-limiting policies:

  • General endpoints: Limited to 100 requests per 15 minutes per IP address
  • Sensitive authentication and write operations: Restricted to 10 requests per 15 minutes per IP address

• Standardized rate-limit violation responses:

  • Returns HTTP 429 Too Many Requests when thresholds are exceeded
  • Includes proper Retry-After headers to inform clients of retry timing and reduce unnecessary request pressure

• Configured server trust settings by enabling trust proxy, ensuring accurate client IP resolution when operating behind reverse proxies or load balancers. This prevents header spoofing and ensures rate limits cannot be bypassed using manipulated client IP headers.

• Applied middleware globally to ensure consistent enforcement across all public routes, eliminating unprotected entry points.

Outcome

The API is now significantly more resilient against traffic abuse and automated attack patterns. Rate limiting enforces fair usage across clients, preserves backend stability under load, and improves overall service availability for legitimate users while maintaining predictable behavior under high traffic conditions.
