Medical Device Security: Key Strategies for Cybersecurity and Data Protection
Core Principles of Secure Medical Device Configuration
Securing medical devices throughout their lifecycle is essential to prevent cyberattacks and safeguard patient safety. With 83% of organizations experiencing multiple breaches and the average cost of a breach in the U.S. reaching $9.44 million, adhering to these principles is not optional - it’s critical[2].
Secure-by-Design Practices
Secure-by-design emphasizes embedding security measures into every stage of medical device development, rather than adding them as an afterthought[2]. This approach creates a solid security foundation, reducing vulnerabilities and making devices inherently more secure[4][5]. As the Cybersecurity and Infrastructure Security Agency (CISA) highlights:
"Every technology provider must take ownership at the executive level to ensure their products are secure by design."[3]
Before development begins, medical device teams should conduct a thorough risk assessment[2]. This process identifies potential threats and incorporates defenses from the outset. Key practices include:
- Using strong encryption to protect patient data during storage and transmission.
- Setting strict access controls to ensure only authorized personnel can interact with devices.
- Regularly updating software to address emerging security threats.
Collaboration between developers and cybersecurity experts is vital to ensure these measures are effectively implemented. Jama Software underscores this point:
"It is not just best practice, but a moral imperative for medical device teams to integrate security into the DNA of their development process. By doing so, they contribute to a safer and more resilient healthcare ecosystem."[2]
Secure design lays the groundwork, but it must be paired with ongoing risk assessments to maintain device integrity.
Risk Assessment and Threat Modeling
Risk assessment and threat modeling are essential for identifying vulnerabilities early in the development process. These methods work hand-in-hand: threat modeling maps out potential attackers, their goals, and tactics, while risk assessment evaluates and prioritizes risks based on their likelihood and potential impact[6].
The FDA has recognized the importance of these practices. In 2020, it funded threat modeling bootcamps through partnerships with MDIC and MITRE, providing industry professionals with training on best practices[7]. Additionally, the "Playbook for Threat Modeling Medical Devices" was developed to help organizations adopt these strategies effectively[7].
To be effective, threat modeling should start during the design phase and adapt as new threats emerge[6]. The FDA requires manufacturers to incorporate cybersecurity considerations into every stage of development, including robust risk assessments and ongoing monitoring for vulnerabilities[6]. Tools like the Microsoft Threat Modeling Tool can assist developers by mapping system components, data flows, and security boundaries, while also suggesting measures to address potential issues[8].
This proactive approach naturally transitions into the need for detailed documentation and transparency.
Configuration Documentation and Transparency
Clear documentation and transparency are cornerstones of secure medical device management. Without sufficient cybersecurity information, a device’s safety and effectiveness can be compromised[9]. Comprehensive documentation ensures users understand a device’s defenses and how to address potential threats[9]. In complex healthcare ecosystems, detailed labeling is crucial for configuring and updating devices securely[9].
Kyle Erickson, Senior Director of CRM Product Security at Medtronic, highlights the importance of visibility:
"We can't protect what we can't see. Supply chain risks exist, and digging into components and dependencies will be necessary to prevent supply chain attacks before an adverse event occurs."[10]
A key tool for enhancing transparency is the Software Bill of Materials (SBOM). Erickson explains:
"SBOMs are the first step to figuring out to identify priorities and what needs patching or mitigating and making that information visible."[10]
The level of documentation should match the device’s cybersecurity risk. High-risk devices require detailed records, including information about communication interfaces, third-party software, and potential vulnerabilities. Inadequate documentation can hinder assessments of whether a device’s safety or effectiveness is at risk[9].
Seth Carmody, Vice President of Regulatory Strategy at MedCrypt, underscores the value of transparency for regulatory oversight:
"That transparency helps regulators gauge the health risk of vulnerabilities impacting devices. Regulators want to trust that manufacturers can assess risk, have transparency in regard to what is in the system, and apply the right mitigations or patches if needed to effectively protect the public safety."[10]
Comprehensive documentation not only helps meet global regulatory requirements but also builds trust with healthcare providers and patients[11].
Best Practices for Configuration Hardening
Configuration hardening strengthens medical devices to protect patient data and maintain operational integrity. By layering defenses, organizations can effectively block unauthorized access and lower security risks.
Authentication and Access Controls
Strong authentication is a cornerstone of medical device security [12].
However, it's crucial to balance robust authentication with the need for efficient clinical workflows. In fast-paced environments, especially during emergencies, authentication methods should never delay patient care - an approach supported by FDA guidance. To address this, consider implementing flexible grace periods that reduce the need for repeated credential entry, helping clinicians work more efficiently. Emergency access, or "break-glass" protocols, can rely on secure methods like biometrics, smart cards, or mobile authentication tools. The choice between single- or multi-factor authentication should align with the device's risk level and clinical use case, in consultation with compliance teams.
Once strong authentication is in place, minimizing unnecessary device features can further reduce security vulnerabilities.
Disabling Unnecessary Features
A key step in reducing a device's attack surface is disabling features that aren't critical to its function. Every unused service, open port, or default account is a potential entry point for attackers. As Christerbell Clincy points out:
"By disabling non-essential network features, we effectively reduce the attack surface. Fewer connected devices mean fewer opportunities for cybercriminals to exploit vulnerabilities." [13]
Some effective hardening practices include:
- Removing default passwords during setup
- Disabling remote access for devices that don’t require external connectivity
- Eliminating test and debugging features before deployment
- Enabling secure boot to ensure only trusted software runs
These steps not only improve cybersecurity but also boost device reliability, simplify compliance efforts, and optimize resource use.
Pairing these measures with secure communication protocols adds another layer of protection.
Secure Communication Protocols and Encryption
Securing communication is essential to safeguard sensitive patient data. Medical devices often transmit critical information, making it vital to protect data both in transit and at rest. A 2017 pacemaker recall [14] highlighted the importance of strong encryption in preventing security breaches.
To address these risks, healthcare organizations should adopt a multi-layered encryption approach. This involves using current algorithms tailored to meet stringent security standards in the healthcare industry. Encryption policies should clearly outline which data need protection - whether stored on the device, transmitted across networks, or processed during clinical operations.
Beyond encryption, maintaining secure communications requires regular updates to software and firmware, routine security audits, and detailed incident response plans. Adding multi-factor authentication further strengthens defenses, ensuring that even if one layer is breached, critical systems remain protected.

Lifecycle Management and Continuous Monitoring
Managing medical device security is not a one-and-done task - it’s an ongoing process. With 74% of healthcare organizations reporting that more than half of their device inventory is connected to networks [17], constant vigilance is essential. In 2021 alone, ransomware attacks cost U.S. healthcare organizations $7.8 billion, and a staggering 68% of vulnerabilities across 2.1 million devices lacked validated patches [17]. This highlights the need for continuous monitoring to strengthen incident response and improve security over time.
Continuous Monitoring and Auditing
Monitoring medical devices effectively begins with establishing a baseline for normal behavior. By understanding how a device typically operates, organizations can quickly identify unusual activity that might signal a cybersecurity threat before it turns into a full-blown breach.
Regular audits are another key component. These audits ensure compliance with both regulatory and cybersecurity standards, while also helping to detect potential threats early. They safeguard the functionality, integrity, and confidentiality of patient data, protect privacy, and ensure devices remain available when needed [1].
Monitoring should include reviewing device logs and tracking any configuration changes that could introduce vulnerabilities. This is especially important in today’s interconnected healthcare systems, where devices often share sensitive patient information across networks. Organizations must also keep an eye out for unauthorized configuration changes and ensure access controls are correctly implemented and maintained.
Incident Response and Recovery
A well-thought-out incident response plan is critical for detecting, containing, and recovering from breaches, minimizing disruptions along the way [15].
An effective response plan includes several phases. The first step is detection and analysis, which allows teams to quickly assess the scope and impact of an incident. Containment and remediation follow, aiming to limit the damage and restore operations as soon as possible. Clear communication throughout the process ensures all stakeholders are kept informed.
Backup and restoration strategies are vital in this context. Organizations need to maintain secure backups of device configurations and test their recovery procedures regularly. This is especially important when dealing with ransomware or other attacks that compromise device integrity. Recovery efforts should also involve close coordination with device manufacturers. As the FDA emphasizes:
"Medical device manufacturers (MDMs) are responsible for remaining vigilant about identifying risks and hazards associated with their medical devices, including risks related to cybersecurity." [16]
This partnership between healthcare providers and manufacturers is essential for effective incident response and recovery.
Security Training and Feedback Loops
Human error is often a weak link in medical device security, making staff training a critical component of any security strategy. Training healthcare workers on cybersecurity best practices and safe device usage can significantly reduce risks. Key topics should include proper authentication procedures, recognizing suspicious activity, and adhering to established security protocols.
Training programs should be tailored to the audience. Clinical staff need to understand how security measures impact their workflows, while IT teams require in-depth knowledge of vulnerabilities and monitoring processes. Regular refresher courses help keep everyone up to date on evolving threats and industry standards.
Preparation doesn’t stop with technical defenses - staff also need to be ready to respond effectively to incidents. Establishing feedback loops allows organizations to learn from past incidents and near-misses. By systematically reviewing these events and incorporating lessons learned into risk assessments and planning, they can prevent similar issues in the future. Creating a culture where staff feel comfortable reporting potential security problems without fear of blame can also help identify risks early.
Collaboration with device manufacturers plays a crucial role here as well. Manufacturers can share updates on newly discovered vulnerabilities and recommend security measures, helping healthcare organizations stay ahead of emerging threats. These feedback loops - both internal and with manufacturers - are invaluable for refining security practices and training programs over time.
Using Tools and Platforms for Configuration Security
When it comes to securing medical device configurations, manual processes and spreadsheets simply can't keep up with the scale and complexity of modern healthcare environments. With a staggering 82% of healthcare organizations experiencing cyberattacks linked to medical device vulnerabilities [22], the need for specialized platforms has become undeniable. These tools are designed to simplify and enhance security operations in a field where the stakes are incredibly high.
Healthcare's unique challenges call for equally unique solutions. As Matt Christensen, Sr. Director GRC at Intermountain Health, puts it:
"Healthcare is the most complex industry... You can't just take a tool and apply it to healthcare if it wasn't built specifically for healthcare." [19]
This demand for tailored solutions has fueled the development of platforms that specifically address medical device security, regulatory compliance, and patient safety concerns.
Benefits of Using Specialized Platforms
Specialized platforms go beyond the manual, error-prone methods of the past. They automate risk assessments, streamline compliance, and centralize configuration management. These systems can evaluate device configurations, pinpoint vulnerabilities, and flag compliance issues in real time. The result? Faster threat detection and resolution, along with a collaborative workspace for IT teams, risk managers, cybersecurity experts, and biomedical engineers.
The compliance advantages are equally critical. With regulations constantly evolving and scrutiny from regulatory bodies intensifying, automated platforms help healthcare organizations stay on top of compliance requirements. They generate audit-ready reports that can save organizations from legal troubles and hefty penalties. As Steve Alder, editor-in-chief of The HIPAA Journal, explains:
"Compliance is important in healthcare because complying with regulations that govern the healthcare industry can help avoid legal risks and penalties for non-compliance, protect the privacy and security of individually identifiable health information, and improve the quality and safety of patient care." [23]
