FCM-Based Model for Network Security Assessment

摘要

A FCM-based model for network security assessment was proposed. According to classified security criteria of information system, factors, criteria, and metrics for network security evaluation were designed. By building hierarchical assessment models and setting reasonable weights, networks' security situation was calculated qualitatively and quantitatively. Theoretical analysis and validation tests show that the model is feasible, and it has objective, comprehensive, and practical features. Thus, it provides a good solution to security evaluation of computer information systems.
