Preparing for Medical Device Cybersecurity Assessments

The medical device industry operates in a high-stakes, highly regulated environment where innovation meets cybersecurity risks. As devices become more sophisticated and interconnected, the attack surface expands, exposing companies to new threats. Regulators like the FDA and the European Commission have responded by tightening cybersecurity mandates, making robust security controls a requirement, not an option.

A company’s design data and intellectual property (IP) are intrinsically tied to its competitive edge and long-term success. Ensuring the confidentiality, integrity, and availability of design data not only protects a company's market position but also facilitates smoother regulatory approvals and fosters trust among stakeholders. While much effort goes into protecting patient data and device functionality, securing the design processes that bring these devices to life is equally crucial.

Let’s explore how medical device manufacturers can prepare for cybersecurity assessments by securing design data and IP, mitigating cyber risks, and leveraging best practices for regulatory compliance.

The Value of Design Data and IP in Medical Devices

In medical device development, design data includes everything from initial schematics to firmware and manufacturing instructions, while IP covers proprietary circuit designs, trade secrets, and algorithms. Protecting these assets is critical not only for maintaining market leadership but also for ensuring compliance and patient safety. When this sensitive information is compromised, it can lead to costly product recalls, competitive disadvantages, and reputational damage. 

Moreover, regulatory bodies increasingly expect companies to have robust mechanisms in place to protect design data from unauthorized access and tampering—see the European Union's Medical Device Regulation (MDR), the U.S. FDA’s latest cybersecurity guidance, and the proposed HIPAA security rule updates. Beyond the financial and compliance risks, the integrity of design data is critical in ensuring that medical devices function as intended, providing safe and reliable solutions to patients.

The FDA specifically highlights the importance of risk management, software transparency, and supply chain security—all areas where design data security plays a critical role.

A compromised design file or tampered firmware could lead to a catastrophic failure in the field, jeopardizing patient safety. According to the Reuters report, the FDA recently identified cybersecurity risks in certain patient monitors, underscoring the growing threat landscape in medical device development. As regulatory scrutiny increases, companies must prove cybersecurity resilience not only in their devices but also in their design processes.

Understanding the Risks: The Expanding Cyber Threat Landscape

As medical devices integrate more digital technologies and become more connected, the attack surface expands, offering malicious actors more opportunities to infiltrate design processes and supply chains and harm your business, its reputation, and its profits. Common risks include:

• Unauthorized Access & Data Breaches: Without strict role-based access controls (RBAC), design data can be exposed to unauthorized parties, leading to the theft of sensitive IP or the tampering of design files. Cybercriminals or even employees with insufficient privileges may exploit weak access controls, leading to IP theft or data leaks, which could be used against the company or its patients.
• Data Tampering & Undetected Alterations: Malicious actors can alter schematics or firmware, leading to compromised device functionality and patient safety risks. A small modification in a design file, if overlooked, can compromise device functionality, introduce safety risks, and cause regulatory noncompliance. Hence, the FDA stresses the need for traceability throughout the design process to detect unauthorized modifications before production.
• IP Theft: Competitors, rogue employees, or nation-state actors may steal proprietary designs, undermining a company’s market position and resulting in significant revenue impacts. Given the lucrative black market for medical technology, companies must secure their design data with encryption and strict access control measures.
• Insider Threats: Employees or contractors with access to sensitive data can inadvertently or maliciously leak information. This threat is particularly concerning when organizations have global teams, where employees might have different security practices or levels of awareness about best practices for securing IP.
• Supply Chain Vulnerabilities: The increasing reliance on global suppliers and third-party contractors introduces additional risks. Counterfeit parts, compromised suppliers, and unvetted vendors can introduce vulnerabilities into the design process, potentially allowing for design flaws, malware insertion, or other security risks.

Best Practices for Protecting Medical Design Data and IP

Regulatory bodies like the FDA and the EU require companies to demonstrate robust security measures throughout the medical device lifecycle. Implementing best practices for securing design data not only helps meet these requirements but also builds a foundation of trust with regulatory agencies. Companies can take proactive measures to protect their sensitive data.

Implement Robust Access Controls

Access to design files should be restricted based on roles and responsibilities. Adopting role-based access control (RBAC) ensures that only authorized personnel can access sensitive data, reducing the risk of internal breaches. Implementing multi-factor authentication (MFA) adds another layer of security by requiring users to verify their identity with something they have (e.g., a smartphone) and something they know (e.g., a password).

Use Secure Collaboration Platforms

In a global development environment, teams often need to collaborate across multiple locations. Using secure cloud-based platforms like Altium 365 allows teams to share design files while maintaining strict security controls. End-to-end encryption ensures that data is protected both in transit and at rest, preventing unauthorized access to sensitive files during collaboration.

Altium 365, for instance, helps engineers and developers collaborate securely from anywhere in the world. This platform integrates access controls, tracking, and security features in real time, ensuring that medical device companies can maintain complete oversight and governance over their design data, no matter where their teams are located.

Track Changes with Version Control

Version control systems track every modification made to design files, providing a complete history of changes. This helps to maintain design integrity while creating an audit trail that can be invaluable during regulatory inspections. By keeping a secure log of each design revision, companies can prove compliance and demonstrate that they’ve taken steps to safeguard data integrity.

Establish a Single Source of Truth

Managing design data in a centralized location reduces the risk of outdated files circulating within the team. A single source of truth ensures that everyone works from the latest version, eliminating confusion and minimizing errors. For medical device companies, this is especially important in environments with multiple stakeholders, including design engineers, regulatory bodies, and manufacturing teams.

Conduct Regular Security Audits and Risk Assessments

Conducting regular security audits and risk assessments helps identify vulnerabilities in the design process. These audits should cover access controls, encryption practices, and the security of third-party tools and suppliers. Regular risk assessments also help identify emerging threats and adapt the security measures accordingly.

Leverage Digital Twin Technology

Digital twins—virtual models of physical devices—are becoming instrumental in medical device development. Teams can simulate device performance, identify potential vulnerabilities early, and streamline regulatory submissions, ensuring greater security and efficiency. Digital twins can help predict the performance of a device under different conditions, allowing teams to test and modify designs without compromising the physical prototypes.

The use of digital twins is especially beneficial in ensuring device functionality and patient safety by allowing engineers to detect potential failures early in the development process, ensuring better outcomes.
