📚 9. Real-World Case Studies

🛑 Unrotated CMKs in FinTech Data Warehouse

Issue: CMKs used in Redshift and S3 had not been rotated in 3 years
Impact: Data residency and PCI compliance violations

🛠️ Our Fix Journey: Healthcare SaaS on Azure

Client: HIPAA-covered SaaS platform
Findings:

  • Multiple client secrets stored without Key Vault

  • Manual key lifecycle without logging or expiry
    Our Role:

  • Hardened encryption architecture with policy-as-code

  • Setup key expiry automation and logging
    Outcome:

  • Passed HIPAA re-certification audit

  • Eliminated plaintext secret risk

📋 11. Sample Encryption Checklist (Preview)

  1. Enable encryption at rest and in transit for all services.
  2. Use cloud-native KMS or HSM for key management.
  3. Define key rotation policies and enforce them automatically.
  4. Limit key access using strict IAM policies.
  5. Monitor key usage and anomalies.
  6. Enable logging for key operations (creation, use, deletion).
  7. Tag and classify keys based on sensitivity.
  8. Ensure key backups and recovery plans are tested.
  9. Use separate keys per environment or business unit.
  10. Enforce customer-managed key usage for sensitive workloads.
