Threat Modeling and Secure System Design Questions
Applying threat modeling and structured problem solving to secure system design. Candidates should be able to decompose complex security challenges by identifying business context, critical assets, threat actors, attack surfaces, and compliance requirements. Topics include threat modeling methodologies, attacker capability and motivation analysis, risk assessment and prioritization, selection of mitigations and compensating controls, and evaluation of trade offs among security, usability, cost, and performance. Candidates should also be able to produce implementation and monitoring plans that address scalability and maintainability and to clearly explain and justify design choices and residual risk to stakeholders.

As a Solutions Architect, explain what threat modeling is and why it's important for designing secure systems. Describe the core outputs of a threat modeling exercise (for example: architecture/DFD diagrams, prioritized threat list, recommended mitigations, assigned risk owners, and monitoring requirements), which stakeholders should participate (engineering, product, security, legal, operations), and how often threat models should be revisited across the project lifecycle (design, pre-release, major changes).

Describe the principle of least privilege and provide a pragmatic approach to implement it for three components: database access for microservices, administrative access to the cloud console, and third-party integrations. Include how you'd verify enforcement and rollback strategies for misconfigurations.

Describe how you would use CVSS scores combined with asset criticality and business impact to prioritize remediation across thousands of vulnerabilities. Outline a simple scoring formula or process, describe automation opportunities, and note important caveats (e.g., exploit availability, internet exposure, service criticality).

Design an automated system that collects compliance evidence from CI/CD pipelines (configurations, test results, deployment manifests) and stores tamper-proof audit trails for regulators and auditors. Describe architecture, data flows, access controls, immutability options (e.g., signed artifacts, object lock), metadata linking (commit, build ID, deploy time), and how to scale the solution for 100+ microservices.

Design an initial threat hunting program for a mid-size enterprise. Detail team composition (roles and skills), essential telemetry sources to prioritize, three detection use cases (for example: credential misuse, insider data exfiltration, lateral movement), hypotheses for each use case, data requirements, and success metrics to measure program effectiveness.
