How should healthcare IT teams secure medical devices and IoMT?
Protecting your healthcare organization requires a proactive, lifecycle-based approach to IoMT security that integrates continuous monitoring, rigorous vulnerability management, and adherence to HIPAA and FDA cybersecurity guidance. Every connected device is an asset to manage and a potential entry point to defend.
As the Internet of Medical Things (IoMT) expands, the attack surface grows with it. From connected infusion pumps to smart patient monitors, each device can be a pathway onto the clinical network. We help healthcare IT teams secure these assets without compromising patient care - because a control that interferes with care will not survive contact with the floor.
This builds on the same principles in our HIPAA risk assessment checklist for healthcare IT leaders and our guide to network segmentation for healthcare data security.
Essential steps for IoMT security
- Comprehensive asset discovery. You cannot protect what you cannot see. Maintain a real-time inventory of every connected device, including its firmware version and network location.
- Network segmentation. Isolate medical devices from the general IT network. Dedicated VLANs limit lateral movement if a single device is compromised. Our managed NGFW and network segmentation guide covers the practical setup.
- Vulnerability management. Scan for known vulnerabilities regularly, and prioritize patching by clinical impact and likelihood of exploitation. Some devices cannot be patched on demand, which makes segmentation and monitoring even more important.
- Strong authentication. Replace default credentials immediately and enable multi-factor authentication wherever the device interface supports it. Default credentials remain one of the most common entry points.
- Continuous monitoring. Deploy tools that flag abnormal traffic - unauthorized command-and-control communication or unusual data exfiltration - so a compromised device is caught early.
IoMT security checklist
| Action item | Suggested frequency | Typical owner |
|---|---|---|
| Asset inventory audit | Monthly | IT security team |
| Firmware / patch review | Quarterly | Clinical engineering |
| Network segmentation test | Semiannually | Network admin |
| Threat intelligence review | Weekly | Security operations |
Frequencies are a starting point; tune them to device criticality and your risk assessment.
Where HIPAA and FDA guidance come in
Medical device security sits at the intersection of two regulatory expectations. Under HIPAA, devices that create, receive, store, or transmit ePHI fall within the scope of the Security Rule’s administrative, physical, and technical safeguards.1 Separately, the FDA publishes guidance on cybersecurity in medical devices, emphasizing threat modeling and vulnerability management across the device lifecycle - from premarket design through postmarket support.2
Two practical implications follow. First, HIPAA documentation must be retained for six years, so keep your device risk assessments, segmentation decisions, and monitoring records on that retention schedule. Second, any third party that touches ePHI - including device vendors and remote-support providers - needs a business associate agreement (BAA) in place before access is granted. See our HIPAA business associate agreement checklist for IT vendors and MSPs.

FAQ: Medical device and IoMT security
What is the biggest risk to IoMT devices?
Default credentials and unpatched vulnerabilities are the most common entry points, giving attackers a foothold to move from a single device onto the broader clinical network.
How does network segmentation help?
It limits the blast radius of an attack. A compromised device confined to its own segment cannot easily reach EHR systems or other critical infrastructure, which contains the damage.
Are there specific FDA requirements for medical device security?
The FDA issues cybersecurity guidance for medical devices that emphasizes threat modeling and vulnerability management throughout the device lifecycle, shaping how manufacturers design and support devices.
How long do we need to keep HIPAA security documentation?
HIPAA requires covered entities and business associates to retain required documentation - including policies, risk assessments, and related records - for six years from the date of creation or last effective date.
Do device vendors need a business associate agreement?
Yes. Any vendor that creates, receives, maintains, or transmits ePHI on your behalf is a business associate and must have a signed BAA in place before they are granted access.
