From fbf43750289e4329b2e3a32f4fe67a0197e5d7e0 Mon Sep 17 00:00:00 2001 From: Richard Shade Date: Fri, 3 Oct 2025 10:46:09 -0500 Subject: [PATCH] feat(azure-yaml): add enterprise SFTP blob storage example with advanced security MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add new Pulumi YAML example demonstrating Azure Blob Storage with SFTP support, featuring enterprise-grade security controls including customer-managed encryption, private network access, and comprehensive audit logging. - **Customer-Managed Encryption**: HSM-backed 4096-bit RSA keys in Azure Key Vault Premium - **Infrastructure Encryption**: Double encryption layer for maximum data protection - **Private Network Only**: Zero public internet access with private endpoints - **Immutable Storage**: WORM compliance with version control and change tracking - **Extended Audit Logging**: 7-year retention for compliance requirements - **Role-Based Access**: Admin and auditor users with granular container permissions - **Latest Azure Native Provider**: Uses Azure Native v3.8+ features and 2024 API versions - **Storage Account**: Data Lake Gen2 (hierarchical namespace) with SFTP enabled - **Key Vault Premium**: HSM-backed customer-managed encryption keys - **Encryption Scope**: Dedicated scope with infrastructure encryption - **Virtual Network**: Isolated VNet with subnets for storage and Key Vault - **Private Endpoints**: Secure access to storage and Key Vault services - **Managed Identity**: Secure Key Vault access without shared keys - **Log Analytics**: Comprehensive monitoring with extended retention ```yaml Encryption: - At Rest: Customer-managed keys (4096-bit RSA-HSM) - In Transit: TLS 1.2+ and SSH - Infrastructure: Double encryption enabled Network Security: - Public Access: Disabled - Private Endpoints: Required - Network Rules: Explicit deny all - Service Bypass: None Access Control: - Authentication: SSH keys only (passwords disabled) - Shared Keys: Disabled - Authorization: Azure AD OAuth - User Types: Admin (full) and Auditor (read-only) Data Integrity: - Immutable Storage: Enabled on all containers - Versioning: Full version control - Change Feed: 7-year audit trail - Soft Delete: 7-year retention ``` - Clean technical implementation guide - Quick start with configuration examples - Architecture diagram with mermaid - Troubleshooting and support information - Minimal length focused on essentials - Healthcare security reference (educational only) - Comprehensive legal disclaimers - Technical security patterns for regulated industries - No compliance guarantees - professional validation required - Reduced from initial 3,754 lines (80% reduction) - Removed excessive operational guides - Focused on practical implementation While this example implements security controls commonly required by healthcare and financial organizations, it includes prominent disclaimers: - ⚠️ No guarantee of HIPAA, PHI, or regulatory compliance - ⚠️ Professional legal and compliance consultation required - ⚠️ Independent security assessment needed for production use - ⚠️ Compliance standards evolve - always verify current requirements Healthcare organizations can reference `HIPAA_COMPLIANCE.md` for additional security considerations, but must validate with their own compliance teams. To test this example: ```bash cd azure-yaml-sftp-blob pulumi stack init dev pulumi config set azure-native:location "East US 2" pulumi config set storageAccountName "testsftpstorage$(date +%s)" pulumi config set userPublicKey "$(cat ~/.ssh/id_rsa.pub)" pulumi preview pulumi up ``` This YAML example can be converted to other languages: ```bash pulumi convert --language typescript --out ./typescript-version pulumi convert --language python --out ./python-version pulumi convert --language go --out ./go-version pulumi convert --language csharp --out ./csharp-version ``` None - this is a new example. Closes #XXXX (if applicable) - [x] Code follows repository standards - [x] Documentation is clear and concise - [x] Example includes architecture diagram - [x] Security best practices implemented - [x] Legal disclaimers for compliance content - [x] Formatting validated with `make format` and `make check_python_formatting` - [ ] Tested deployment with `pulumi preview` - [ ] Tested full deployment cycle (requires Azure environment) 1. **Legal Review**: The HIPAA_COMPLIANCE.md file includes extensive legal disclaimers. Please validate these are sufficient to protect against liability claims. 2. **Azure Syntax**: Some Pulumi YAML syntax should be validated during review: - Managed identity property structure (line 150) - `getClientConfig` function syntax (lines 60, 108) - Subnet array indexing (lines 393, 414) - BlobService versioning property name (line 212) 3. **Security Configuration**: All security features use latest Azure Native provider capabilities. Review that: - Customer-managed keys are properly configured - Infrastructure encryption is enabled at all layers - Private network access is enforced correctly - Audit logging captures all required events 4. **Documentation Scope**: Intentionally kept documentation minimal (755 lines total) to avoid overwhelming users. More detailed operational guides were removed as they were too extensive for an example. This example was created in response to requests for: - Modern SFTP support in Azure with latest security features - Customer-managed encryption implementation patterns - Healthcare/compliance-ready infrastructure examples (with appropriate disclaimers) - Pulumi YAML examples demonstrating complex Azure architectures --- azure-yaml-sftp-blob/.gitignore | 107 +++++ azure-yaml-sftp-blob/HIPAA_COMPLIANCE.md | 563 +++++++++++++++++++++++ azure-yaml-sftp-blob/Pulumi.yaml | 511 ++++++++++++++++++++ azure-yaml-sftp-blob/README.md | 194 ++++++++ 4 files changed, 1375 insertions(+) create mode 100644 azure-yaml-sftp-blob/.gitignore create mode 100644 azure-yaml-sftp-blob/HIPAA_COMPLIANCE.md create mode 100644 azure-yaml-sftp-blob/Pulumi.yaml create mode 100644 azure-yaml-sftp-blob/README.md diff --git a/azure-yaml-sftp-blob/.gitignore b/azure-yaml-sftp-blob/.gitignore new file mode 100644 index 0000000000..ff813a07c7 --- /dev/null +++ b/azure-yaml-sftp-blob/.gitignore @@ -0,0 +1,107 @@ +# Pulumi +.pulumi/ +Pulumi.*.yaml + +# OS +.DS_Store +Thumbs.db + +# Logs +*.log +logs/ + +# Runtime data +pids +*.pid +*.seed +*.pid.lock + +# Backup files +*.backup +*.bak + +# Temporary files +*.tmp +*.temp + +# Secrets and sensitive data +secrets/ +*.pem +*.key +id_rsa +id_rsa.pub +*.p12 +*.pfx + +# Generated files +generated/ +dist/ +build/ + +# Language-specific (for converted versions) +# Node.js +node_modules/ +npm-debug.log* +yarn-debug.log* +yarn-error.log* +package-lock.json +yarn.lock + +# Python +__pycache__/ +*.pyc +*.pyo +*.pyd +.Python +env/ +venv/ +pip-log.txt +pip-delete-this-directory.txt +.pytest_cache/ + +# Go +# Binaries for programs and plugins +*.exe +*.exe~ +*.dll +*.so +*.dylib +vendor/ +go.sum + +# C# +bin/ +obj/ +*.user +*.suo +*.userprefs +packages/ +.vs/ + +# Java +target/ +.m2/ +*.jar +*.war +*.ear +*.class + +# IDE +.idea/ +.vscode/ +*.swp +*.swo +*~ + +# Azure CLI +.azure/ + +# Test results +test-results/ +coverage/ +*.cover +.coverage +.pytest_cache + +# Documentation build +docs/_build/ \ No newline at end of file diff --git a/azure-yaml-sftp-blob/HIPAA_COMPLIANCE.md b/azure-yaml-sftp-blob/HIPAA_COMPLIANCE.md new file mode 100644 index 0000000000..dfa77dca81 --- /dev/null +++ b/azure-yaml-sftp-blob/HIPAA_COMPLIANCE.md @@ -0,0 +1,563 @@ +# Healthcare Security Reference - Azure SFTP Blob Storage + +## ⚠️ IMPORTANT LEGAL DISCLAIMERS ⚠️ + +**NO GUARANTEE OF COMPLIANCE**: This document provides technical guidance and examples for implementing security controls that may be relevant to healthcare organizations.
