Risk Heat Map
Maximum business impact (highest of the six category scores) plotted against disruption likelihood, following the NIST SP 800-34 Rev. 1 risk characterization approach. Chips are colored by assigned tier; select any application for its full BIA record.
Business Impact →
Risk zone: Low (<5) Moderate (5–9) High (10–14) Severe (≥15)
Chip border = tier:T0T1T2T3
Ranked Risk Register
Impact × likelihood, descending
Likelihood reflects architecture fragility, vendor concentration, platform age, and outage history gathered during BIA interviews — not threat-actor probability. Methodology note: impact axis uses the maximum of the six category scores to avoid averaging away single-category severity.
