ExpertGCP PCA · Question 11 · Domain 3: Designing for Security and Compliance
CASE STUDY: HealthData Corp
Overview: Healthcare SaaS managing 10PB of sensitive patient records and imaging.
Business: Strict HIPAA/SOC 2 compliance, ransomware protection, secure sharing of anonymized data with researchers, robust DR.
Executives:
- CEO: "Trust is our product. Zero tolerance for breaches."
- CFO: "Storage costs growing exponentially. Need lifecycle management."
- CISO: "Zero-trust architecture, end-to-end encryption."
Tech: RPO 15m, RTO 2h for core DB. All data CMEK encrypted. Strict access controls, audit logging. Prevent data exfiltration.
Constraints: Images retained 7 years but rarely accessed after 90 days. Researchers use external identities. No public IPs on compute.
How should you design the network security architecture to prevent data exfiltration, even if an employee's credentials are compromised?
