From the first hello, the Locknet® team is dedicated to serving you and your needs.
The rapid growth of connected medical devices has transformed patient care. Infusion pumps, imaging systems, cardiac monitors, and even nurse call systems are now integrated into clinical networks, enabling real-time data sharing and operational efficiency. But this connectivity has also dramatically expanded the attack surface within healthcare environments.
For clinic administrators, IT directors, and compliance leaders in healthcare organizations, medical device cybersecurity is an operational and patient safety risk.
According to recent industry analysis, FBI Cyber Division data shows that more than half of medical devices averaging 10 years in deployment lack basic security features such as encryption or authentication. Even more concerning, it’s estimated roughly one in five connected medical devices operate on unsupported or outdated operating systems that no longer receive security updates.
For independent clinics with limited IT resources, these statistics represent real and immediate exposure.
Unlike traditional IT systems, many connected medical devices were designed primarily for clinical performance, not security. Historically, FDA cybersecurity requirements did not mandate robust controls. Before updated guidance and legislation took effect from 2023-2025, manufacturers were not required to embed comprehensive cybersecurity safeguards into their products.
As a result, many legacy devices:
This creates a dangerous gap. Attackers can exploit unpatched vulnerabilities to gain a foothold inside a clinic’s network. From there, they may move laterally to access electronic health records, billing systems, or other sensitive infrastructure.
More alarming is the potential for patient safety risk. Vulnerabilities in infusion pumps, imaging systems, or monitoring devices can potentially allow manipulation of treatment parameters or disruption of clinical workflows. For small clinics that rely heavily on uptime and patient trust, even brief disruptions can damage safety and reputation.
The regulatory landscape has shifted significantly between 2023 and 2025. Under the PATCH Act and related FDA guidance, cybersecurity is now formally treated as part of medical device safety.
As of 2025, manufacturers seeking FDA approval for a “cyber device” must:
Failure to maintain these processes is now considered a prohibited act.
While this is a positive development, it does not eliminate provider responsibility. Hospitals and clinics must still implement patches, manage configurations, segment networks, and retire unsupported devices. Hospital cybersecurity compliance extends beyond employee healthcare record (EHR) systems to every connected device in the clinical environment.
One of the most common mistakes in healthcare cybersecurity planning is treating medical device security as solely the responsibility of IT.
In reality, effective medical device cybersecurity requires collaboration across multiple departments:
For small independent clinics, these roles may overlap. A clinic administrator or COO may also oversee compliance and IT strategy. That makes cross-functional coordination even more critical.
Security must be considered from acquisition through decommissioning. If procurement selects devices based solely on clinical function and cost, without evaluating security posture, the organization may inherit long-term risk.
While providers cannot redesign devices themselves, they can significantly reduce risk through practical, structured controls.
You cannot protect what you cannot see. Maintain a real-time inventory of all connected medical devices, including:
Many breaches begin because organizations lack visibility into IoT medical device security exposure.
Network segmentation is one of the most effective defenses. Place connected medical devices on separate VLANs or isolated network zones. Limit communication strictly to required systems.
This prevents a compromised device like an infusion pump from becoming a gateway into financial or patient record systems.
Many devices ship with default passwords. These should be changed immediately upon deployment. Disable unnecessary services and ports wherever possible.
Work closely with device vendors to understand update schedules and patch availability. Document a formal process for testing and deploying updates to avoid disrupting clinical operations.
For unsupported legacy devices that cannot be patched, implement compensating controls such as strict network isolation and enhanced monitoring. Develop a phased replacement plan when feasible.
Traditional antivirus solutions often cannot be installed directly on medical devices. Instead, deploy network-based monitoring tools capable of detecting abnormal traffic patterns or suspicious behavior from IoT devices. Early detection is critical to minimizing operational disruption and protecting patient safety.
Request SBOMs and cybersecurity documentation from vendors. Ask questions like:
This aligns purchasing decisions with long-term hospital cybersecurity compliance obligations.
Medical device risk should be integrated into your broader healthcare cybersecurity risk assessment. Document findings and remediation plans to demonstrate due diligence during audits or investigations.
The following FAQs address common concerns and questions related to medical device cybersecurity in healthcare settings.
Legacy devices often run on unsupported operating systems and cannot receive security patches. Many lack encryption or strong authentication, making them easier targets for attackers and difficult to secure with modern controls.
Manufacturers must meet FDA cybersecurity requirements, but providers are responsible for maintaining devices in their environment. This includes applying patches, segmenting networks, monitoring activity, and managing risk throughout the device lifecycle.
Cyber vulnerabilities can potentially allow attackers to disrupt device functionality or alter treatment parameters. Even if patient harm does not occur, downtime or compromised systems can delay care and disrupt clinical operations.
Start with a comprehensive inventory of all connected medical devices. Visibility is the foundation for effective risk management, network segmentation, patching, and long-term compliance efforts.
Hospitals and clinics require cybersecurity solutions that work seamlessly, yet the rise of connected medical devices brings complex risks that shouldn’t be ignored. The rapid growth of IoMT devices has expanded the attack surface, and outdated systems with weak security controls increase the risk of data breaches, operational disruptions, and patient harm.
Fortunately, practical measures can significantly reduce these threats. Ensuring strong medical device cybersecurity is essential for patient safety, regulatory compliance, and maintaining the trust patients place in healthcare providers.
