DRAFT: HIPAA Network Standard

Purpose

This standard defines the networking requirements for workloads that create, store, process, transmit, or provide access to Protected Health Information (PHI) within University-managed Azure environments.

The standard establishes requirements for workload isolation, secure connectivity, network governance, operational visibility, and integration with approved enterprise services.

Scope

This standard applies to:

  • HIPAA applications
  • HIPAA databases
  • HIPAA data products
  • HIPAA platform services
  • HIPAA integrations
  • HIPAA infrastructure
  • Network services supporting HIPAA workloads

within approved HIPAA hosting environments.

Requirements

1. Network Isolation

HIPAA workloads must be deployed within approved network architectures designed to provide appropriate workload isolation and security boundaries.

Network architectures must support segregation of HIPAA workloads from non-regulated workloads.

2. Dedicated HIPAA Hosting Boundaries

HIPAA workloads must operate within approved HIPAA subscriptions and approved network boundaries.

Networking designs must align with approved hosting and landing zone architectures.

3. Approved Connectivity

Network communications must be restricted to approved and necessary communication paths.

Connectivity must be governed through approved architecture standards and operational processes.

4. Ingress Control

Inbound connectivity to HIPAA workloads must be explicitly governed, managed, and monitored.

Unauthorized inbound access paths must not be permitted.

5. Egress Control

Outbound communications from HIPAA workloads must follow approved connectivity paths and approved enterprise networking requirements.

Outbound communications must be governed according to approved security and operational requirements.

6. Network Segmentation

HIPAA workloads must implement logical network segmentation appropriate for workload architecture, operational management, and security requirements.

Segmentation must support workload separation and administrative control.

7. Private Connectivity

Private connectivity mechanisms should be used when supported by the target platform, service, or application architecture.

Network architectures should minimize unnecessary public exposure of HIPAA services.

8. Shared Service Connectivity

HIPAA workloads may communicate with approved enterprise shared services when authorized through approved architecture standards and governance processes.

Shared service connectivity must follow approved security and operational requirements.

9. Identity Service Connectivity

Network architectures must support connectivity to approved enterprise identity services required for authentication, authorization, and access governance.

Identity communications must follow approved security controls.

10. Monitoring Integration

Network architectures must integrate with approved enterprise monitoring and logging services.

Network-related activities must support operational visibility, auditability, troubleshooting, and incident investigation.

11. Data Protection Support

Network architectures must support approved data protection controls, including encryption requirements and data protection standards applicable to HIPAA workloads.

Networking implementations must not circumvent approved protection requirements for regulated data.

12. Operational Visibility

Network services supporting HIPAA workloads must generate monitoring and audit information sufficient to support:

  • Operational support
  • Security investigations
  • Compliance activities
  • Audit reviews
  • Incident response

13. Governance Alignment

HIPAA network architectures must align with approved governance controls inherited through Management Group placement and related platform governance processes.

14. Architecture Review

Networking implementations that deviate from approved network architecture patterns require architecture review and approval before implementation.

15. Exceptions

Exceptions to this standard require documented approval through the approved architecture exception process.
