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.
