An effective medical device security program must consider the Medical Equipment Lifecycle (MELC). MELC divides medical device management into four parts. Each part needs special security actions:
This process helps healthcare groups keep devices safe from purchase to disposal.
Before buying a new device, healthcare managers and IT staff must do careful risk checks. They should look at:
The FDA will ask manufacturers to share SBOMs from 2023, giving healthcare places better knowledge of software parts and making risk checks more accurate.
Since more than half of hospital IoMT devices had serious security problems in a 2022 report, these early checks are very important. They help keep unsafe devices out of healthcare networks.
After buying devices, putting them to use is another chance for risks to enter. IT teams should:
Working with IoMT cybersecurity experts can help set up secure deployments. For example, some big health systems use platforms that watch connected devices all the time. They find problems like strange network traffic quickly.
Deployment can be hard because devices are complex and many types exist. But it is a key step for device security.
Once devices are working, healthcare groups must stay alert. They should:
Security teams need tools that send real-time alerts about device health. Continuous monitoring is important because over half of hospital IoMT devices show critical risks. It is not safe to check them only sometimes.
Old devices can cause the biggest security problems if they stay connected after they are done being used. These devices might not get security updates and can be attacked.
Healthcare groups should:
Failing to remove devices right can cause data leaks, service stops, or harm patients. Working with device makers and security experts helps a lot during this step.
Security is not just about technology. People matter too. Healthcare places should:
Well-trained workers make fewer mistakes and reduce inside risks that might break device security. Constant education helps staff stay up-to-date on new threats and rules.
New artificial intelligence (AI) and automation can help improve device security. AI software can study huge amounts of device data, network traffic, and security reports faster than people.
Here are some ways AI and automation help:
AI tools help reduce workload and improve accuracy in managing device security. As devices get more complex, using AI is a good step for healthcare groups across the U.S.
Protecting medical devices needs teamwork. Healthcare groups cannot do it alone. Working together with:
One example is a partnership of a large hospital and a cybersecurity provider. They shared data and found strange network activity linked to patient monitors. This helped fix problems quickly and keep devices working well and patients safe.
Healthcare managers should keep open communication with manufacturers and security experts to manage risks fully.
Setting up medical device security programs can be hard because of:
To handle these problems, healthcare groups should:
Hospitals and clinics can lower cyber risks by following these steps carefully. This will help keep patients safe and meet federal rules.
Healthcare organizations in the U.S. face big risks from unsecured medical devices. But following the Medical Equipment Lifecycle can reduce these risks well. By doing good risk checks, securing networks, monitoring devices, training staff, retiring devices properly, and using AI while working closely with manufacturers and security experts, healthcare leaders can protect patients, data, and systems effectively.
The Medical Equipment Lifecycle (MELC) is a framework for managing medical devices from initial purchase through maintenance to eventual disposal. It helps maintain device integrity throughout its lifetime and is essential for ensuring cybersecurity in the Internet of Medical Things (IoMT).
The four stages are: 1) Pre-Procurement, involving risk assessments; 2) Deployment, focusing on securing network-connected devices; 3) Operation, managing device vulnerabilities; and 4) Decommissioning, ensuring legacy devices are secured before disposal.
Manufacturers are responsible for designing and testing medical devices to comply with security standards. They must provide ongoing support, including addressing new risks and releasing necessary upgrades or patches to secure devices post-release.
HDOs must create secure networks, conduct regular vulnerability scans, and manage updates efficiently. Implementing strict access controls and ensuring collaboration with manufacturers and IoMT cybersecurity providers are crucial for maintaining security.
HDOs often struggle when manufacturers do not release timely patches for vulnerabilities. Budget constraints and the complexity of decommissioning outdated devices can also hinder effective risk management and security efforts.
Collaborative efforts between manufacturers, HDOs, and IoMT cybersecurity providers facilitate better risk management, enhance communication about vulnerabilities, and lead to more comprehensive security measures across the Medical Equipment Lifecycle.
Steps include: 1) Conducting comprehensive risk assessments; 2) Implementing access controls; 3) Regularly monitoring devices for anomalies; 4) Keeping devices updated with security patches; and 5) Establishing ongoing security training programs for staff.
MDS2s provide essential information on securing medical device components, while SBOMs list all software installed on a device. Both are crucial for managing vulnerabilities and ensuring devices remain secure over time.
IoMT cybersecurity providers help assess risk levels, identify security gaps, and provide strategies for risk management. They can handle the monitoring and operational aspects of medical device security throughout the equipment lifecycle.
One example is a health system with patient monitor issues. Collaboration with Asimily revealed abnormal network traffic, allowing for corrective action. The partnership enhanced the system’s security posture and improved device functionality.
