We compare the performance of three growth models – Gompertz, Logistics, and Exponential -using security breaches data from the fifteenth annual report of the Computer Security Institute. Unlike other studies, multiple components (frequency of attacks and dollar loss value) are utilized to model the growth of security breaches thereby providing a balanced understanding of the undesirable phenomenon. The findings indicate that multiple- dimensional approach to modeling security breach approach seems more rigorous than the single-dimension found in the literature. The two components seem to be different and each explains an aspect of security breach growth rate. Frequency of attacks provides a slightly better fit than dollar loss value in all three models.
