摘要: 为解决入侵检测系统漏检后的网络安全防御问题,利用平台层动态目标防御技术,设计一种新的平台动态防御(PDD)策略。结合隔离区PDD系统,分析PDD运行原理,考虑平台响应入侵检测告警的随机选择平台迁移以及漏检情况下固定时间间隔的主动迁移,给出PDD策略和防御效能评估指标。仿真结果表明,该策略在异常事件和入侵检测系统漏报率增多的情况下能够始终保持较高的费效比,可有效解决防御收支不平衡和入侵检测系统漏报带来的安全隐患问题。

Abstract: In order to solve the network security defense problem after the intrusion detection system misses detection,using the Moving Target Defense(MTD) technology of the platform layer,this paper designs a new dynamic defense strategy for platforms.Combined with the dynamic defense system of the platform in Demilitarized Zone(DMZ),the dynamic defense operation principle of the platform is analyzed.Considering the active platform migration at fixed intervals caused by missed intrusion detection and random platform migration caused by detected intrusion alarms,a dynamic defense strategy for platform and an evaluation index for defense effects are given.Simulation results show that the proposed strategy always maintains a high cost-effectiveness ratio in the case of abnormal events and an increased false negative rate of the intrusion detection system,which can effectively solve the imbalance between defense costs and effects and the security risks caused by missed detection of the intrusion detection system.

Key words: Moving Target Defense(MTD), dynamic defense for platform, event-driven, timing migration, intrusion detection
