Critical Infrastructure Cascade: Cyberattack Propagation & Containment

Modern cyberterrorism rarely stops at one target — power grids feed water treatment, water treatment cools hospital equipment, telecom carries the SCADA control traffic that ties them all together. This simulator models that interdependency as a graph of six critical-infrastructure sectors and runs a real independent-cascade model: a compromise at one node gets a per-edge chance to spread to every dependent neighbour, governed by attack intensity, network segmentation, and each sector's redundancy investment. Raise segmentation to sever cascade paths, raise redundancy to shorten containment time, and watch which combination keeps a single-sector breach from becoming a cross-sector emergency — the same dynamic that drives real Zero Trust and OT/IT segmentation policy for national critical-infrastructure defense.
