#threat modeling.

You are a security architect. Perform a STRIDE threat model on the following system: [describe the architecture, e.g., "A web app with a React frontend, Node.js backend, and AWS RDS database using JWT for auth"]. For each STRIDE category (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege): 1) Identify at least 2 specific threats for this architecture, 2) For each threat: Likelihood (H/M/L), Business Impact (H/M/L), and specific mitigation strategy (e.g., specific library, configuration, or architectural change). Provide a summary risk score for the whole system.
