Executive Summary
A comprehensive security guide covering token rotation, rate-limiting algorithms, query depth limiting, and zero-trust authentication.
API security requires defense-in-depth across the entire network and application perimeter.
1. Sliding Window Rate Limiting Prevent credential stuffing, scraper bots, and denial-of-service attempts by implementing Redis sliding window rate limiters per IP and authenticated user token.
2. GraphQL Query Complexity & Depth Limiting GraphQL endpoints are inherently vulnerable to recursive query attacks (e.g. author -> posts -> author -> posts). Enforcing a maximum query depth of 5 and calculating AST complexity scores before execution prevents backend resource exhaustion.
3. Cryptographic Token Storage & Rotation Never store authentication tokens in client-side `localStorage`. Instead, employ HTTP-only, Secure, `SameSite=Strict` cookies with cryptographically signed refresh token rotation.
