When a hospital's MRI scanner gets hit by ransomware or a networked infusion pump broadcasts unencrypted patient data, the biomedical engineering team is now on the front line — not just IT. OxMaint's CMMS tracks patch status, network segmentation compliance, and vulnerability remediation for every connected medical device in your fleet, giving biomedical teams a single audit trail that satisfies both FDA postmarket cybersecurity guidance and hospital IT security requirements. The threat is real: healthcare suffered more cyberattacks than any other sector in 2024, and 83% of connected medical devices run on unsupported operating systems.

Cybersecurity for Networked Medical Devices: A Maintenance Team Responsibility
Patch management, network segmentation verification, and vulnerability tracking are now biomedical maintenance responsibilities — here is how CMMS brings them under one roof with full compliance documentation.

Why Biomedical Teams Own Device Cybersecurity Now
The FDA's 2023 Consolidated Appropriations Act and subsequent postmarket cybersecurity guidance formally shifted responsibility for connected medical device security onto the device lifecycle — which means biomedical engineering, not just IT. Patch deployment, SBOM verification, segmentation checks, and vulnerability tracking must now be documented as part of the equipment maintenance record. OxMaint connects these tasks to existing PM workflows so they are tracked, timestamped, and reportable alongside every other maintenance activity.

The 4-Layer Medical Device Cyber Defense Stack
Effective medical device cybersecurity is not a single tool — it is a layered approach where each layer depends on the one below it. Biomedical teams are responsible for Layers 1 and 2; IT owns Layers 3 and 4. OxMaint's CMMS is the documentation spine that makes all four layers auditable.

Device Cyber Compliance
The FDA's postmarket cybersecurity guidance has fundamentally changed the biomedical engineering role. Patch management and vulnerability tracking are now maintenance activities — they need to live in the same system as PMs and work orders, with the same documentation standards. A CMMS that does not track cybersecurity tasks alongside physical maintenance is no longer fit for purpose in a modern hospital biomedical program. OxMaint's approach of embedding cyber checklists directly into PM work orders is exactly the right architecture for this regulatory environment.

Frequently Asked Questions
Does FDA require biomedical teams to document medical device cybersecurity activities?
Yes — the 2023 Consolidated Appropriations Act and FDA's postmarket cybersecurity guidance require manufacturers and healthcare organizations to maintain records of patch deployment, vulnerability remediation, and network segmentation compliance. For health systems, this means biomedical departments must document cybersecurity tasks in a way that is retrievable for FDA inspections and TJC surveys.
OxMaint's CMMS creates this documentation automatically as part of normal work order completion — no separate cyber-tracking system required.
What is MDS² and how does OxMaint help track manufacturer cybersecurity disclosures?
MDS² (Manufacturer Disclosure Statement for Medical Device Security) is the standardized document that medical device manufacturers provide to disclose the cybersecurity capabilities and risks of their devices. OxMaint stores MDS² documents against each device record and creates automatic work orders when advisories are issued by the manufacturer — ensuring your team receives, reviews, and responds to every disclosure with a documented audit trail.

Can OxMaint track network segmentation compliance for medical devices during scheduled PMs?
Yes — OxMaint supports custom checklist items embedded directly into PM work orders. Your biomedical team adds a network segmentation verification step to the annual PM checklist for connected devices — confirming the device is on the correct VLAN, firewall rules are active, and no unauthorized connections are detected. Completion of this step is timestamped and recorded, creating the documented evidence that both IT security and TJC EC.02.04.01 audits require. Devices that fail segmentation checks automatically generate a corrective work order assigned to IT.
How does OxMaint handle devices with manufacturer-only patch rights — where biomed cannot directly apply updates?
OxMaint tracks the patch status of every device regardless of who applies the patch. For devices where the OEM performs all firmware and software updates, OxMaint manages the service request to the manufacturer, tracks the expected completion date, and documents the patch version and date when the OEM confirms completion. This means your CMMS record always reflects actual patch status — including OEM-serviced devices — giving you a single complete view of your fleet's cybersecurity posture even when update authority is split between your team and the manufacturer.
Medical Device Cybersecurity Is a Maintenance Responsibility. Manage It Like One.
