Your question is Threat Modeling a New Microservice. 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).
Walk me through your process for conducting a threat modeling exercise on a new microservice.
Focus on how you identify assets, trust boundaries, and likely abuse paths, then turn that into concrete controls and monitoring. Assume the service will handle sensitive Autodesk customer and design data, but do not invent a full product scenario.
