基于粗糙集和D-S证据理论的系统安全评估
System Security Assessment Based on Rough Set and D-S Evidence Theory
摘要
Abstract
Aiming at the problem that traditional security management system can not reflect the security status of the entire system, a method based on rough set and D-S evidence theory is presented. It uses attribute reduction and attribute values reduction in rough set theory to optimize the evaluation indicators and get the simplest rules, determines the value of the evidence in the rough set and D-S theory combination rules according to the importance of the attribute in the decision table, gets Basic Probability Assignment(BPA) based on the decision table and establishes a system security assessment model. Experimental result shows that this method can optimize evaluation indicators, get the simplest rules, and improve the reliability of security assessment.关键词
