# Cloud for Sovereignty Compliance Guide
|
||||
|
||||
**Last Updated**: 2025-01-27
|
||||
**Status**: Comprehensive Compliance Framework
|
||||
**Standard**: Microsoft Cloud for Sovereignty
|
||||
|
||||
## Overview
|
||||
|
||||
This document outlines how The Order project achieves and maintains compliance with Microsoft Cloud for Sovereignty requirements, ensuring data residency, operational control, and regulatory compliance.
|
||||
|
||||
## Compliance Requirements
|
||||
|
||||
### 1. Data Residency
|
||||
|
||||
**Requirement**: All data must remain within specified geographic regions and never be replicated to non-approved regions.
|
||||
|
||||
**Implementation**:
|
||||
- ✅ Azure Policy enforcement for region restrictions
|
||||
- ✅ Regional resource groups and storage accounts
|
||||
- ✅ Database geo-restrictions
|
||||
- ✅ CDN regional restrictions
|
||||
- ✅ No cross-region data replication (except for DR)
|
||||
|
||||
**Verification**:
|
||||
```bash
|
||||
# Check resource locations
|
||||
az resource list --query "[].{Name:name, Location:location}" --output table
|
||||
|
||||
# Verify policy compliance
|
||||
az policy state list --filter "complianceState eq 'NonCompliant'"
|
||||
```
|
||||
|
||||
### 2. Operational Sovereignty
|
||||
|
||||
**Requirement**: Customer maintains control over operations with limited Microsoft access.
|
||||
|
||||
**Implementation**:
|
||||
- ✅ Customer-managed encryption keys (CMK)
|
||||
- ✅ Azure Lighthouse for customer control
|
||||
- ✅ Independent logging and monitoring
|
||||
- ✅ Customer-managed backups
|
||||
- ✅ Audit trail independence
|
||||
|
||||
**Key Vault Configuration**:
|
||||
- Premium SKU with HSM-backed keys
|
||||
- Soft delete and purge protection enabled
|
||||
- Private endpoints only
|
||||
- Customer-managed keys for all services
|
||||
|
||||
### 3. Regulatory Compliance
|
||||
|
||||
**Requirement**: Compliance with local regulations, data protection laws, and industry standards.
|
||||
|
||||
**Implementation**:
|
||||
- ✅ GDPR compliance (EU data protection)
|
||||
- ✅ eIDAS compliance (electronic identification)
|
||||
- ✅ ISO 27001 alignment
|
||||
- ✅ SOC 2 Type II readiness
|
||||
- ✅ Industry-specific compliance
|
||||
|
||||
**Compliance Dashboards**:
|
||||
- Azure Policy compliance dashboard
|
||||
- Microsoft Defender for Cloud compliance
|
||||
- Regulatory compliance reporting
|
||||
- Audit log retention (90 days production, 30 days dev)
|
||||
|
||||
