1. A computer-implemented method for quantifying correlated risk in a network of a plurality of assets having at least one dependency, each asset belonging to at least one entity, the method comprising:

  • generating a dependency graph based on relationships between the plurality of assets, the at least one dependency, and the at least one entity, wherein;

    each of the plurality of assets is selected from the group consisting of;

    Internet Protocol (IP) address, domain name, and server system;

    each of the at least one entity is selected from the group consisting of;

    a company and an organization; and

    each of the at least one dependency is selected from the group consisting of;

    hosting provider and software version;

    executing a plurality of Monte Carlo simulations over the dependency graph by;

    generating a seed event in the dependency graph, the seed event having a probability distribution; and

    propagating disruption through the dependency graph based on the seed event;

    assessing loss for each asset of the plurality of assets; and

    aggregating losses in a nonlinear sum for two or more assets of the plurality of assets to determine correlated risk in the network.
