Security Design Frameworks Questions

Covers formal approaches and mental models used to design secure systems end to end. Candidates should be able to clarify scope and requirements, enumerate and prioritize assets, build data flow and trust diagrams, perform threat modeling and risk assessment, and map security controls to attacker profiles. This topic includes frameworks such as Scope Assets Layers Tradeoffs and other step by step design approaches that force explicit assumptions, constraints, and failure modes. Interviewers will probe how a candidate balances security goals against performance, cost, operational complexity, and user experience, and how they document and communicate design decisions to engineering and product partners. Expect to discuss how frameworks guide control selection, testing strategies, and incremental rollout plans.
