【 摘 要 】

Hadarics et. al. gave a Mathematical Model for DistributedVulnerability Assessment. In this model the extent of vulnerability of aspeci c company IT infrastructure is measured by the probability of atleast one successful malware attack when the users behaviour is also incorporatedinto the model. The di erent attacks are taken as independentrandom experiments and the probability is calculated accordingly. Themodel uses some input probabilities related to the characteristics of thedi erent threats, protections and user behaviours which are estimated bythe corresponding relative frequencies. In this paper this model is furtherdetailed, improved and a numerical example is also presented.
