Medical IoT Devices: The Expanding Attack Surface in Hospitals

Why medical IoT devices resist traditional endpoint security, and the network segmentation strategies hospitals use to manage the resulting risk.

A Hospital Full of Unmanaged Endpoints

Infusion pumps, imaging equipment, and patient monitors are increasingly network-connected, yet many run outdated operating systems that can't be patched without vendor involvement or risking device certification.

Why Traditional IT Security Doesn't Transfer

Standard endpoint security agents often can't be installed on medical devices at all, since doing so can void the manufacturer's regulatory clearance. Hospitals need a different security model for this category of device entirely.

Network Segmentation as the Primary Control

Isolating medical IoT devices onto dedicated network segments, with strict rules about what they can communicate with, is the most reliable control available when the devices themselves can't be hardened directly.

A Shared Responsibility with Manufacturers

Procurement contracts that require manufacturers to commit to a patching timeline and vulnerability disclosure process are becoming a standard, and necessary, negotiating point for hospital IT.
