A Patient Safety Approach for Assessing Medical Device Vulnerabilities

As healthcare systems grow increasingly connected, the risk of medical device vulnerabilities expands with it. This joint whitepaper by Medcrypt and The AbedGraham Group provides a clinically informed, patient safety-driven approach to evaluating and prioritizing vulnerabilities in connected medical devices. Using real-world use cases and quantitative analytics, it demonstrates how technical flaws like Ripple20 and BlueKeep translate into tangible clinical, operational, financial, and regulatory risks; and offers a framework for mitigation that aligns with both cybersecurity and patient safety objectives.

Traditional vulnerability scoring systems (e.g., CVSS) don’t capture the real-world clinical impact of a cyber event. A vulnerability that seems minor on paper could disrupt patient care, while others may be less impactful than headlines suggest. This paper reframes vulnerability management through a patient safety lens, helping both manufacturers and healthcare delivery organizations prioritize threats based on how they affect clinical workflows and outcomes — not just technical severity.

• Vulnerabilities must be assessed within clinical context, not in isolation.
• Ripple20 and BlueKeep highlight systemic risks in connected care environments.
• CVSS scores alone fail to convey the patient safety implications of device exploits.
• A dual proactive/reactive approach — “shift security left” during design, then monitor continuously — offers the most sustainable defense.
• Collaboration between manufacturers and providers is essential for effective risk management and regulatory compliance.
