Securing APIs: Anti‐Forgery, CORS, HTTPS, etc.?

Short answer: HTTPS: Enforced via UseHttpsRedirection() CORS: Limit origins using policies Anti-forgery: Usually not needed for APIs unless using cookies (use ValidateAntiForgeryToken) Use authentication + authorization checks for all endpoints

Real-world example (ShopNest)

A ShopNest checkout request flows through middleware, hits a minimal API or controller, uses scoped services, and returns ProblemDetails on errors.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
