Abstract: In this paper, the necessity and feasibility of quantitative security evaluation are analyzed, in particular with regard to nowadays security requirements. Based on the probability and statistics, the quantitative security model is brought forward. And then a complete quantitative evaluating system is introduced, which is based on the modularization and the quantitative security model. Finally, the rationality and validity of this system are verified through experiments.
