Why Healthcare Cybersecurity Is Hard

Healthcare technology has the potential to transform care delivery — but its benefits are only as strong as the security that underpins them.
This whitepaper explains why healthcare cybersecurity remains uniquely difficult, identifying six systemic constraints that hinder progress across medical device manufacturers (MDMs), healthcare delivery organizations (HDOs), and regulatory agencies.

By framing cybersecurity challenges through economic, operational, and regulatory lenses, this paper clarifies why security debt accumulates across the healthcare ecosystem — and how proactive, secure-by-design strategies can begin to reverse it.

Despite spending $10–20 billion annually on cybersecurity, the healthcare sector consistently ranks among the most targeted and least secure industries.
Regulatory fragmentation, economic misalignment, and clinical priorities often push security down the list of business imperatives.
As a result, security debt — vulnerabilities that originate from design, integration, or maintenance — is passed downstream to hospitals and patients.

Understanding these constraints is the first step toward systemic reform. This whitepaper provides insight into how industry and regulators can rebalance incentives, reduce security debt, and build sustainable, resilient healthcare technology systems.

‍

• Medical Device Manufacturers (MDMs): executives, engineering, and product security leaders
• Healthcare Delivery Organizations (HDOs): CISOs, CIOs, and clinical engineering teams managing complex connected environments
• Regulators and Policy Makers: professionals working across FDA, HHS, and Congress on cybersecurity policy
• Industry and Security Researchers: seeking to understand the economic and systemic challenges of securing healthcare

• Healthcare’s cybersecurity problem is structural, not technical.
• Security debt originates with technology producers and compounds across the ecosystem.
• Adversaries exploit fragmented governance and inconsistent oversight.
• Regulatory models built for static systems (like drugs) are ill-suited for dynamic software ecosystems.
• True resilience will require continuous feedback loops between design, deployment, and monitoring — not one-time compliance.

1. Introduction: The Reality of Connected Healthcare
   
   1. How connectivity improved clinical outcomes and efficiency — and introduced new risks
   2. The concept of security debt as inherited technical debt
2. Constraint 1: Healthcare Optimizes for Healthcare
   
   1. Economic incentives favor clinical innovation over cybersecurity investment
   2. Why medical device manufacturers prioritize healthcare features over secure-by-design principles
   3. Impact on resource allocation, regulatory strategy, and time-to-market
3. Constraint 2: Security Debt Accumulates and Manifests for Consumers
   
   1. How vulnerabilities propagate from technology producers to consumers (HDOs and patients)
   2. The imbalance between who creates security risk and who bears the cost
   3. Real-world data: hospitals spend billions annually managing inherited security debt
4. Constraint 3: Adversaries Exist
   
   1. The shift from opportunistic to targeted cyberattacks on healthcare systems
   2. Case studies: WannaCry, NotPetya, and ransomware attacks on major hospital systems
   3. How healthcare’s financial pressures amplify cyber risk exposure
5. Constraint 4: Security Requires Deep Specialization
   
   1. Why expecting clinicians or HDO IT teams to handle product security is unrealistic
   2. The cost of in-house security expertise vs. leveraging commercial solutions
   3. The danger of “rolling your own” cryptography and bespoke security implementations
6. Constraint 5: U.S. Healthcare Governance Is Fragmented
   
   1. Mapping the fractured regulatory ecosystem — FDA, HHS, CMS, OCR, FTC, FCC, and others
   2. Why oversight gaps leave system interfaces under-secured
   3. The need for coordinated national security-by-design policy
7. Constraint 6: Uncertainty Breaks Existing Risk Models
   
   1. Why medical device software cannot be regulated like drugs
   2. Limitations of static, deterministic quality frameworks (cGMP vs. dynamic systems)
   3. The FDA’s evolving position on adaptive regulation and real-time postmarket feedback
8. Conclusion: Reducing Uncertainty, Reducing Debt
   
   1. The case for continuous, data-driven security monitoring across product lifecycles
   2. Building shared accountability among regulators, MDMs, and HDOs
   3. How security innovation, not just compliance, will drive the next phase of healthcare safety
