Your question is Securing APIs in Microservices. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How do you secure APIs in a microservices architecture?
Discuss authentication, authorization, API gateway controls, service-to-service trust, secrets management, transport security, abuse prevention, and monitoring. Explain how your design handles compromised credentials, replay attacks, excessive traffic, and failures without creating a single point of failure.
