SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Hardening a service reduces the attack surface by enforcing authentication, input validation, rate limiting, and security headers, while promoting safe secrets handling.

Core Features & Use Cases

  • Implement Auth Middleware: enforce authentication and authorization on protected endpoints.
  • Add Input Validation and Security Headers: validate user input and apply appropriate headers to prevent common web vulnerabilities.
  • Enable Rate Limiting and CORS: throttle requests and configure safe cross-origin resource sharing.
  • Use Case: Harden a REST API behind a public gateway to prevent unauthorized access and data leakage.

Quick Start

Configure auth, add input validation, enable rate limits, and apply security headers to harden your service.

FAQPage Schema
How do I harden a REST API with authentication and rate limiting?

To harden a REST API, you enforce authentication middleware, validate user input, apply rate limiting, and set security headers. This reduces the attack surface and prevents unauthorized access to protected endpoints.

Does this service hardening approach work with FastAPI and Express?

Yes, this service hardening approach works across modern web frameworks including Express, FastAPI, Django, Rails, and Go net/http. It provides end-to-end guidance for adding auth middleware, CORS, and security headers to these environments.

What's the best way to add input validation and security headers to a web service?

The best way to add input validation and security headers is to apply middleware that validates user input and enforces appropriate headers. This prevents common web vulnerabilities and improves overall security posture.

How do I configure CORS and secrets management for a public gateway API?

You configure CORS and secrets management by setting safe cross-origin resource sharing policies and handling credentials securely. This protects public gateway APIs from data leakage and unauthorized cross-origin requests.

When do I need to implement auth middleware and rate limiting on my endpoints?

You need auth middleware and rate limiting when exposing services behind a public gateway. Authentication enforces authorization on protected endpoints while rate limiting throttles requests to prevent abuse.
