Abstract

There is a great demand from the viewpoint of security insurance to calculate the value of damage due to leakage of personal information. The Japan Network Security Association(JNSA) proposed a model to calculate the damage compensation amount. However, the coefficient was determined by experts' subjective evaluations for which there is no basis. We propose a new mathematical model by applying multiple regression using cyber incident records and information such as enterprise size as explanatory variables and the value of extraordinary losses to a company as a target variable. We apply the damage model to 15,000 cyber incidents, compare the two models' loss amounts, and consider the relationship between them.
