Overview
Google Cloud Platform with Assured Workloads holds FedRAMP Moderate authorization for government cloud storage and computing. It provides compliance guardrails for data residency and access controls.
CUI Risk Assessment
FedRAMP authorized at Moderate impact level. Approved for CUI handling in DoD environments.
Using Google Cloud Government in a Defense Contractor Environment
Google Cloud Government (GCG) with Assured Workloads is specifically designed for defense contractors handling CUI categories including ITAR-controlled technical data, financial information, acquisition sensitive information, and operational security data. Within CMMC Level 2 authorization boundaries, GCG typically serves as the primary cloud infrastructure hosting contractor applications, databases, and file storage systems. The FedRAMP Moderate authorization provides baseline security controls, but contractors must implement additional Assured Workloads policies for data residency, personnel screening, and access logging to meet DFARS 252.204-7012 requirements. DCMA and DIBCAC assessors consistently evaluate GCG deployments by reviewing Assured Workloads configuration, examining data flow diagrams to ensure CUI remains within authorized regions, and validating that contractor personnel have implemented proper identity federation with government-approved identity providers. Recent DCMA compliance reviews have highlighted GCG as a positive example when properly configured with Assured Workloads, particularly noting its comprehensive audit logging and automated compliance monitoring capabilities. However, assessors frequently cite contractors who deploy standard Google Cloud Platform instead of the Government offering, resulting in immediate CMMC findings. The tool's integration with contractor Active Directory systems and support for PIV/CAC authentication makes it particularly suitable for DoD environments requiring strong identity assurance.
Deployment & Architecture
Deployment Model: Government Cloud (FedRAMP boundary)
Google Cloud Government operates within a FedRAMP-authorized boundary. CUI can be processed within the authorization scope, but contractors must verify their specific use case falls within the system's security boundary as documented in the SSP.
Implementation Guide
Defense contractors already using Google Cloud Government should focus on proper Assured Workloads configuration rather than migration, requiring 4-6 weeks for full compliance implementation. Phase 1 (weeks 1-2) involves enabling Assured Workloads policies for data residency and personnel access controls, including configuring location restrictions to approved regions (us-central1, us-east4) and implementing data sovereignty controls. Phase 2 (weeks 3-4) requires integrating contractor identity systems with Google Cloud Identity, configuring PIV/CAC authentication, and establishing proper role-based access controls aligned with least privilege principles. Phase 3 (weeks 5-6) involves comprehensive testing of audit logging, backup procedures, and incident response workflows. CUI data handling during configuration changes requires implementing temporary access restrictions and maintaining detailed change logs for CMMC documentation. User training focuses on Assured Workloads console navigation, proper data classification procedures, and incident reporting protocols, typically requiring 8 hours per technical user. Compliance documentation updates include modifying the SSP to reflect Google Cloud Government architecture, updating authorization boundary diagrams to show data flows within FedRAMP boundaries, and creating POA&M entries for any temporary configuration gaps. Configuration costs range from $15,000-$30,000 for consulting services plus ongoing Assured Workloads premium of approximately 20% above standard Google Cloud pricing.
Configuration Checklist
- 1ISSO shall enable Google Cloud Assured Workloads with data residency controls configured for approved US regions to meet DFARS 252.204-7012 data sovereignty requirements.
- 2System administrator shall configure organization-level policies restricting data storage to us-central1 and us-east4 regions within the Assured Workloads compliance framework.
- 3ISSO shall integrate Google Cloud Identity with contractor Active Directory using SAML federation and enable PIV/CAC authentication for all CUI system access.
- 4System administrator shall implement IAM policies enforcing least privilege access controls and configure conditional access policies based on device compliance status.
- 5ISSO shall enable Cloud Audit Logs with 7-year retention for all administrative actions and data access events to support NIST 800-171 AU controls.
- 6System administrator shall configure Google Cloud Security Command Center with custom rules for detecting unauthorized data access or configuration changes.
- 7ISSO shall update the System Security Plan to document Google Cloud Government architecture, data flows, and Assured Workloads control implementation.
- 8ISSO shall modify authorization boundary diagrams to clearly delineate FedRAMP Moderate boundary and contractor-controlled cloud resources.
- 9Contracts officer shall validate that Google Cloud Government usage aligns with contract data handling requirements and DFARS flowdown clauses.
- 10System administrator shall implement automated backup procedures with encryption in transit and at rest using customer-managed encryption keys stored in Cloud KMS.
Compliance Cross-References
Google Cloud Government's FedRAMP Moderate authorization directly supports NIST 800-171 control families including AC (Access Control) through integrated IAM and conditional access policies, AU (Audit and Accountability) via comprehensive Cloud Audit Logs with immutable storage, SC (System and Communications Protection) through encryption in transit and at rest with customer-managed keys, and SI (System and Information Integrity) via Security Command Center monitoring. The platform triggers DFARS 252.204-7012 compliance obligations for CUI handling and 252.204-7021 requirements for cybersecurity incident reporting through automated logging and monitoring capabilities. For CMMC Level 2 assessments, Google Cloud Government impacts all assessment domains but particularly strengthens Asset Management (AM), Access Control (AC), and System and Information Integrity (SI) practices through its native security controls. The FedRAMP Moderate authorization provides a foundational security baseline that contractors can leverage to demonstrate compliance with underlying NIST 800-53 controls, reducing assessment scope for inherited controls while requiring contractors to implement organizational-level controls for data classification, personnel security, and incident response procedures.
