A malware protection method to protect at least a subset of a set of computer systems from a malware includes accessing a model of the set of computer systems, the model identifying interacting pairs of the computer systems in the set based on interactions corresponding to previous communication occurring between the computer systems in the pair; simulating, over a plurality of time periods, a propagation of the malware originating from a predetermined source computer system in the model, the simulation being based on a number of interactions per time period between each interacting pair of computer systems in the set, and a rate of transmission of the malware per interaction; and, responsive to the simulating, identifying one or more computer systems or interacting pairs of computer systems to deploy a malware protection measure thereto so as to inhibit a propagation of the malware through the set of computer systems.

Malware propagation forecasting

A computer implemented malware protection method to protect at least a subset of computer systems in a population of network-connected computer systems, including determining a distribution of predicted final infection size, each predicted final infection size being determined by a forecasting simulation of malware propagation from an originating system in the population; determining a plurality of ranges of final infection size from the distribution; determining weighted associations between clusters of computer systems and ranges of final infection size based on measures of numbers of originating computer systems in each cluster associated with each range of final infection size; and deploying protective measures for one or more clusters of computer systems responsive to the weighted associations.
