HITRUST CSF v11: Domain 09 Network Protection & Medical Data Enclaves
Implementing HITRUST Common Security Framework (CSF) Domain 09 network security controls for healthcare payers, providers, and SaaS vendors.
Regulatory Context & Scope
HITRUST CSF provides a comprehensive certifiable framework harmonizing HIPAA, NIST, ISO, and PCI standards for healthcare organizations.
Key Required Network Controls
Control 09.m: Network Routing Control - Restricting network routing to ensure traffic does not traverse unauthorized intermediate networks.
Control 09.o: Segregation of Networks - Establishing dedicated enclaves for electronic health record (EHR) processing systems.
Control 09.s: Security of Network Services - Enforcing explicit authorizations for third-party medical billing and insurance EDI gateways.
