Practical implementation guide for network architects designing zero-trust segmentation for acute care and diagnostic imaging suites.
Effective segmentation begins with asset classification: separating life-support devices, diagnostic imaging systems, patient entertainment networks, and clinical workstations into discrete security trust tiers.
Policies should enforce least privilege: an MRI scanner requires access to PACS and radiology reporting servers, but must be barred from accessing general hospital web portals or administrative printers.
Combining microsegmentation with automated behavioral telemetry enables hospital security teams to detect port scans or lateral probing within seconds, automatically isolating suspect nodes without human intervention.
