CLAIR Model Empowers Defenders to Map and Mitigate Infrastructure Cascade Risks

The SANS diary recently unveiled the CLAIR (Critical Infrastructure Interdependency) model, a systems‑of‑systems framework that charts how the nation’s essential sectors—energy, transportation, finance, health, and more—rely on each other. By visualizing these links, defenders can pinpoint where a cyber‑physical breach in one domain could trigger downstream failures across the entire ecosystem.

For security teams, CLAIR turns abstract interdependencies into actionable intelligence. It supports risk‑based prioritization, realistic cascade simulations, and coordinated response planning across agencies. In an era where a ransomware hit on a power grid can cripple hospitals and disrupt supply chains, adopting the CLAIR model helps defenders anticipate ripple effects, close blind spots, and bolster the overall resilience of critical infrastructure.
