Security and Compliance Architecture Questions

Architecting systems to meet security requirements and regulatory and compliance obligations. Candidates should understand how to embed data classification, data governance, encryption, least privilege access, audit trails and logging, secure design patterns, and threat modeling into architectures. Expect discussion of how architectural choices affect obligations under common regulations such as the General Data Protection Regulation, the Health Insurance Portability and Accountability Act, the Payment Card Industry Data Security Standard, and System and Organization Controls frameworks. Topics include documenting architecture for compliance reviewers, retention and data residency considerations, denial of service mitigation and web application firewall strategies, and balancing security controls with usability and operational cost. Candidates should be able to describe when to engage legal and compliance teams and how to design for auditability and evidence capture.

An auditor has requested proof that cryptographic keys used for customer data are never exported in plaintext and are rotated according to policy. Describe how you would architect the key lifecycle (generation, storage in HSM, usage patterns, rotation, backup, destruction) and list the artifacts and evidence (logs, KMS audit trail, HSM attestation) you would provide.

Design a cross-cloud Bring-Your-Own-Key (BYOK) architecture where a customer's keys remain in their on-prem HSM and cloud workloads perform cryptographic operations without keys leaving the HSM. Describe the connectivity model, latency and throughput considerations, failover strategy, and controls to prove to compliance teams that keys never left customer control.

Design a secrets-management approach for a CI/CD pipeline that deploys to multiple clouds. Cover secure storage (Vault/Secrets Manager), injection patterns (sidecar, vault agent, ephemeral credentials), rotation, access controls, and how you would prevent secrets from leaking into build logs or ephemeral runners.

What is a Web Application Firewall (WAF)? Describe two common deployment patterns (inline reverse-proxy WAF vs. CDN-integrated WAF) and explain when you would recommend each for a client concerned about OWASP Top 10 vulnerabilities and automated bot traffic.

Explain how to design least-privilege access for microservices using service identities, mutual TLS (mTLS), and a centralized authorization service (policy engine). Describe how to manage role changes, emergency break-glass access, and how to audit and roll back policy changes.
