DORA ICT Cascade Simulator

Monte Carlo simulation of ICT incident propagation across a financial institution's dependency graph. 500 stochastic BFS paths model cascade failure from a single point of compromise through interconnected systems — returning time-to-disruption percentiles, P(DORA reporting threshold breached), and critical path identification aligned to Articles 17–25.

ICT Topology Preset

Defines the dependency graph structure. Node count: 16–18.

Initial Failure Node

Secondary Failure Node (optional)

Cascade Threshold — 50%

Fraction of a node's dependencies that must fail to trigger cascade propagation.

MTTR Profile

Mean time to recovery multiplier applied to each node's base MTTR.

Simulation Paths

Chain from ART-09 Artifact (optional)

Links this simulation's provenance to an upstream DORA incident classification.
