The SMART Toolkit: Mapping Healthcare's Critical Dependencies
The Health Sector Coordinating Council Cybersecurity Working Group has released the Sector Mapping and Risk Toolkit (SMART), a 16-month initiative born from the Change Healthcare attack in February 2024. The toolkit provides 17 workflow maps covering critical healthcare functions from blood supply distribution to claims processing, pharmaceutical manufacturing, and dialysis services. Each map visualizes the complex web of third-party dependencies that support daily healthcare operations, offering organizations a template to identify single points of failure and concentration risks. The toolkit is designed to be scalable, serving both large health systems with complex vendor ecosystems and smaller practices with simpler workflows. By making the invisible infrastructure visible, SMART enables healthcare organizations to understand where their critical dependencies lie and what would happen if those services were disrupted.
Materiality Assessment and Risk Prioritization
The toolkit introduces a structured approach to measuring material impact across clinical, administrative, financial, and regulatory dimensions. Organizations use the maps to assign relative risk ratings to third-party services based on factors including cybersecurity hygiene, market concentration, and geographic risk. This materiality framework helps healthcare entities prioritize where to invest in risk mitigation and where to focus on resilience planning. For services where organizations have market leverage, they can demand better security practices or switch providers. For concentrated markets where a single vendor controls 70-80% of the market, the focus shifts to right-of-boom preparedness — developing continuity plans, backup procedures, and manual override capabilities. The methodology acknowledges that not all risks can be mitigated, but all can be prepared for through awareness and planning.
Industry Collaboration and Future Evolution
The SMART toolkit represents a collaborative effort involving approximately 460 organizations across the healthcare spectrum, including providers, payers, medical technology companies, pharmaceutical manufacturers, and health IT firms. The working group deliberately excluded AI-driven workflows from the current version, recognizing that AI's role in healthcare automation is still maturing too rapidly to capture accurately. The toolkit is positioned as a living document that will evolve based on user feedback and industry changes. Early adopters have already begun implementing the maps, with one healthcare provider presenting lessons learned just six weeks after publication. The working group is actively seeking feedback on accuracy, usability, and implementation experiences to refine future versions. This sector-led approach mirrors similar critical infrastructure mapping efforts in financial services, where visualization of systemic dependencies helped government agencies understand where to focus preparedness and recovery resources.
