Module 10

Security Boundaries: API Keys, Auth Concepts, and CORS

By the end of this module you can reason about API keys, authentication and CORS as boundaries - and explain why CORS is a browser rule, not a security control.

Units

  1. Unit 10.00: What an API key does and does not prove
  2. Unit 10.01: Where credentials belong, and where they leak
  3. Unit 10.02: Authorisation is not authentication
  4. Unit 10.03: CORS, and what it actually protects
  5. Unit 10.04: Rate limits and the state they need
