Shared Responsibility Pci Soc2 Service Tiers

What the Solution Is

In the Google Cloud shared responsibility model, compliance and operational obligations vary significantly across Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) models. To validate compliance for cloud-hosted environments, customers must manage their scoped responsibilities while leveraging Google Cloud Compliance Reports Manager (or designated compliance resources) to download independent third-party attestations like SOC 2 reports and PCI Attestation of Compliance (AOC) documents.

How It Meets the Requirements

• IaaS (Compute Engine): Google manages physical data center security, host hardware, and the hypervisor layer. The customer retains full responsibility for the guest operating system, OS security patching, firewall rules, and application-level hardening.
• PaaS (Cloud SQL): Google assumes responsibility for the underlying VM provisioning, OS maintenance, database engine binary patching, and hardware reliability. The customer is responsible for logical access management (IAM and database users), database connection security (SSL/TLS), table-level access, and data configuration.
• SaaS (Google Workspace): Google manages the entire infrastructure, application software, and service availability. The customer is responsible for identity governance, multi-factor authentication (MFA), context-aware access policies, and data classification.
• Compliance Evidence: Independent third-party audit reports, including Google's SOC 1/2/3 reports and PCI DSS AOC, provide the necessary verification of Google's underlying control environment to regulatory bodies and external auditors.

Key Advantages and Capabilities

• Clear Audit Demarcation: Allows the security team to accurately scope customer-controlled audit requirements versus provider-certified controls.
• Automated Evidence Collection: Provides direct access to current audit certificates and third-party reports via compliance management portals.
• Reduced Operational Overhead: Leveraging PaaS and SaaS shifts infrastructure and runtime patching responsibilities to Google, reducing the customer's direct PCI DSS control surface.

Why This Is Optimal

This solution correctly delineates control ownership at each specific cloud service abstraction level and establishes a defensible audit trail using official third-party compliance attestations.
