Getting specific about what HDOs need in device visibility and insights CMMS data deficits must be resolved quickly, accurately, and continuously. Creating a single source of device data truth goes a long way to supporting ongoing risk abatement and workflow efficiencies that help keep operations secure. To achieve this, HDOs need to feed their CMMS dynamic information and validate it against existing CMMS data fields. This level of dynamic information should include specific details on the device model, make, OS version, network status, security posture, utilization, and location. Therefore, data solutions need to apply advanced deep packet inspection (DPI) techniques combined with vast medical expertise, so they can identify and capture relevant device details and consider the clinical context in which these devices are operating. Clinical context, after all, is crucial because medical devices are not like other IT devices. For example, most clinical devices are closed systems, and AV or security agents cannot be downloaded to protect them. They run proprietary or legacy software that can’t be patched unless approved and authorized by the manufacturer. This means vulnerabilities may persist, and devices may be open to exploit for the duration of the patch/fix process. They also often leverage proprietary or clinical protocols to communicate, so to identify activity that could pose a threat, these protocols need to be fluently understood. Since most clinical devices serve a specific function and act a certain way, they’re much more predictable than general computer systems controlled by people. However, this is only useful if the workflows and manufacturer-defined behaviors of the specific device are known. HDOs are unique because they require solutions with a level of knowledge that don’t produce a lot of false alarms on activity that is perfectly normal (and necessary) for a medical device’s operation. Probably the most important (and somewhat obvious) thing to be mindful of is that clinical devices are used in procedures and treatment plans, so protective measures cannot be disruptive. If access to a ventilator is blocked or an IV pump is prevented from communicating with a patient monitor simply because it was moved, powered up, or made a new connection, an unnecessary point of failure is introduced that can impact patient care and outcomes. All these things need to be considered and accommodated in device management and security decisions. Cyber Defense eMagazine – December 2021 Edition 102 Copyright © 2021, Cyber Defense Magazine.

The benefits are great When HDOs have real-time visibility and insights into their inventory, they can start to streamline and mature their security, BioMed, and IT workflows to lower risks and costs. For instance, they can use device location and utilization information to understand front-line care team preferences, improve patch planning, and optimize asset distributions, which can ultimately generate significant CAPEX and OPEX benefits. With a wide-angle view of where devices are used, HDOs can determine when to purchase new equipment or even reallocate devices from under-utilized locations to optimize capacity and meet needs. They can consider the risk posture of devices in their buying, renting, and leasing decisions; automate vulnerability correlations to pinpoint impacted devices (e.g., with an OS version-specific problem, outdated firmware, vulnerable application entity, etc.); and trigger associated remediation work orders that reduce the overall risk to operations. Automating device data collection and management routines allows HDOs to make data-driven decisions that increase their security posture, improve the lifecycle of their fleet, and drive operational savings. It’s essential not only for the sanity of HTMs (no more frantic searches for equipment) but also the HDO at large – benefiting their patients, balance sheet, and ongoing operations.
