Implements defense-in-depth security patterns to protect REST APIs from abuse, injection attacks, and data leakage.
API Hardening provides Claude with a comprehensive set of security patterns to secure web services across Express, FastAPI, and serverless environments. It enables the implementation of critical defense layers including Redis-backed distributed rate limiting, robust input validation using Zod, and secure CORS configurations. By following these industry-standard patterns, developers can safeguard their applications against common vulnerabilities like SQL injection, XSS, and brute force attacks while managing API keys securely through hashed storage and tiered access control.
Key Features
01Industrial-grade API key generation and hashed storage management
02Schema-based input validation and sanitization using Zod and DOMPurify
03Prevention strategies for SQL injection and Cross-Site Scripting (XSS)
