To trust a computer system that is supposed to be secure, it is necessary to predict the degree to which the system’s security level can be achieved when operating in a specific environment under cyber attacks. In this paper, we propose a state-based stochastic model for obtaining quantitative security metrics representing the level of a system’s security. The main focus of the study is on how to...
