Healthcare is one of the most targeted industries for cyberattacks because it holds valuable patient information and provides important services. A report from IBM in 2020 showed that the average cost of a health data breach was $7.13 million. Also, ransomware attacks on healthcare providers almost doubled between 2022 and 2023, with over 1,000 facilities having service interruptions in 2024.
Medical devices often have weaker protection than other digital systems. Many use outdated software, do not encrypt data, or have weak password controls. These problems make them easy targets for cyberattacks. For example, a ransomware attack in the MercyOne healthcare system affected infusion pumps, which could have caused wrong medication doses. Such attacks can harm patients, reduce trust, and cause big fines.
The U.S. Food and Drug Administration (FDA) works to improve medical device cybersecurity. The Consolidated Appropriations Act of 2023 has Section 524B, which requires manufacturers to submit detailed plans about cybersecurity for new devices. These devices must have security features from their first design through their entire use.
Key Cybersecurity Risks Affecting Medical Devices
- Ransomware and malware attacks: These can lock devices or systems, stopping their use and delaying care.
- Unauthorized access: Weak passwords or poor login controls can let hackers change device settings or get patient data.
- Data breaches: Theft of patient data stored or used by devices can expose personal health information.
- Software vulnerabilities: Old or unpatched software might have weak spots hackers can use.
- Insider threats: Mistakes by staff or intentional misuse can also cause security problems.
These risks show the need for constant monitoring, quick updates, and strong access controls designed for medical devices in healthcare networks.
Regulatory Frameworks and Standards Guiding Medical Device Cybersecurity
Healthcare organizations in the U.S. must follow federal rules and shared standards to improve cybersecurity.
- FDA Guidance and Laws: The FDA requires device makers to use good cybersecurity practices throughout the product’s life. This includes submitting risk management plans as required by the 2023 Act.
- NIST Cybersecurity Framework (CSF): Used widely in healthcare, it helps organizations manage cybersecurity by identifying risks, protecting assets, detecting incidents, responding, and recovering.
- IEC 62304 and ISO 14971: These international standards focus on safe software processes and risk management for medical devices.
- ANSI/AAMI SW96: Offers guidance on cybersecurity for healthcare organizations related to medical devices.
- HIPAA: Sets rules to protect patient data privacy and security, affecting how devices handle health information.
Hospitals and clinics need to follow these rules to stay compliant and keep patients safe.
Proactive Risk Management and Asset Governance
Heather Afriyie’s 2025 review highlights four important parts for good medical device cybersecurity in hospitals:
- Risk Assessment and Management: Hospitals should regularly check for weaknesses and decide which ones need fixing first. This helps find high-risk devices.
- Device Lifecycle Management: Managing devices through buying, using, fixing, and retiring them ensures timely updates and replacement. Older devices tend to have more problems.
- Organizational Alignment and Collaboration: Cybersecurity is not just IT’s job. It needs teamwork from administration, clinical staff, and tech teams to keep security without disturbing work. Shared rules help make clear who does what.
- Governance and Accountability: Clear policies and leadership roles, like a security officer, are needed to keep track and enforce cybersecurity rules.
Using several layers of security and always improving helps healthcare organizations change their plans when new threats appear.
Simulating Medical Device Cyber Incidents for Preparedness
Simulations help improve readiness for cyber threats. Tabletop exercises, technical tests, and mixed simulations allow healthcare groups to find weak spots and test their responses before real attacks happen.
According to practices used by Censinet’s RiskOps
platform, simulations should have real-time watching, detailed logs, and change with new threats. Systems like STRIDE (which sorts threats like spoofing and tampering) and ISO 14971 help check device risks in an organized way.
Regular simulation training also helps staff know their roles during cyber incidents. This improves how fast they respond and lowers possible harm to patients.
Addressing Legacy Device Vulnerabilities
Many healthcare groups still use old medical devices that don’t support modern security. These devices stay in use because replacing them is expensive or they are needed for operations. They increase cybersecurity risks. To handle these devices, organizations should:
- Separate their network to isolate old devices from the main hospital network.
- Keep watching for unusual activity.
- Replace or upgrade them slowly with newer, safer devices.
- Limit who can use or manage old equipment with strict access controls.
These actions need planning but are important to lower security risks.
Strengthening Workforce Cybersecurity Practices
Human mistakes are a big cause of healthcare data breaches. Studies show insider-related threats made up almost 58% of healthcare data breaches according to the Verizon 2020 Data Breach Investigations Report. So, regular training for the workforce is very important. Training should be:
- Made for clinical and office roles.
- Updated each year and include phishing test exercises.
- Based on real examples showing what happens when cybersecurity fails.
Keeping records of this training is also key for following rules and getting ready for audits.
AI and Automated Workflow Integration in Medical Device Cybersecurity
Artificial intelligence (AI) and automation are being used more to improve cybersecurity in healthcare. These tools help reduce manual work and improve spotting and fixing risks.
AI-Based Threat Detection: AI looks at network activity and device actions all the time, learning what is normal. It can find ransomware, unauthorized access, or device tampering faster than regular tools.
Workflow Automation: Automated patching helps IT teams update many devices quickly with little downtime. Automation also helps find risks, combine alerts, and speed up incident responses.
Data Integrity Verification: Blockchain is starting to be used to keep safe and unchangeable logs of device actions and data sharing. This helps with audit checks and following the rules.
Collaboration Platforms: AI risk management tools like Censinet RiskOps let healthcare groups do continuous risk checks, compare security levels, and work safely with vendors.
For U.S. medical groups, using AI for cybersecurity fits with federal guidelines that promote a proactive defense. Automating routine security tasks frees IT teams to focus on important improvements and working with clinical staff.
Balancing Security with Clinical Workflow
Cybersecurity in healthcare must work alongside the need to provide steady patient care. Matthew Clarke, a healthcare cybersecurity expert, says that IT staff, clinicians, and administrators should all share responsibility for security. Involving clinicians in picking security tools makes sure these tools do not slow down daily work.
Security solutions should be easy to use and adjustable to help people accept them. Communication between IT and clinical teams helps fix worries about how security affects patient care.
Leaders also need to give enough resources and recognize staff efforts. Rewarding safe actions helps create a culture where cybersecurity is part of healthcare without stopping it from working well.
Technology and Security in Device Procurement
Buying medical devices is a key way to prevent cybersecurity problems. Healthcare leaders must demand strong security in new devices, such as:
- Proof that the manufacturers follow FDA cybersecurity rules.
- Software that can be updated and follows secure coding methods.
- Inclusion of a Software Bill of Materials (SBOM) for transparency and fast vulnerability checks.
- Regular checks of vendor security levels.
Contracts should also state how long devices will last and plans for when they are no longer supported to encourage upgrades.
Continuous Monitoring and Incident Response
Constant monitoring helps catch cyber threats to medical devices early. Healthcare groups should use network separation, firewalls, intrusion detection, and controlled access. Backups and encryption protect patient data even if devices are attacked.
Plans for incident response must be clear, with frequent drills for staff training. Simulations and updated guides help contain problems quickly, reduce patient harm, and keep healthcare services running.
Medical device cybersecurity needs ongoing work from healthcare leaders, IT staff, and clinical teams. Following rules, managing risks, training workers, and using AI tools help U.S. healthcare organizations protect patients, keep trust, and defend medical systems from cyber threats.
