Security Architecture Patterns and Tradeoffs Questions

Reusable security patterns and the decision making required to select and apply them. Candidates should be able to propose authentication and authorization models, role design and least privilege patterns, secure inter service and application programming interface communication patterns, encryption and key management approaches, secrets management and rotation practices, secure configuration baselines and hardening patterns, and assume compromise design approaches. Coverage includes selection criteria for patterns, control placement, and the trade offs between security, performance, cost, complexity, and operational burden. Candidates should also be able to communicate risk and security benefits to non technical stakeholders and know when to escalate to specialist security or cryptography experts.
