PHI Network Isolation
Patient data networks kept in their own lanes (VLANs), separate from guest Wi-Fi, medical devices, vendor and office traffic, designed so a problem in one does not reach the others. EHR (electronic health record) and clinical-system traffic isolated to defined VLANs with documented access controls. Inter-VLAN policy enforced at the firewall, with logged deny traffic for audit. Segmentation diagrams kept current and presentable to auditors on demand.
