针对关键服务安全态势分析难的现状,本文提出一种新颖的服务安全态势感知模型(SSSA),并对服务数据源进行分类描述,将用户质量需求的性能参数,服务本身的可生存性以及服务运行的软硬件配置信息三方面作为影响服务态势变化趋势特征的重要因素.通过捕获DNS服务的态势数据来验证模型的可行性.实验结果表明模型对检测服务变化趋势具有良好的灵敏度,能够有效地检测服务偏离和失效,为安全管理员正确决策提供支持.
In view of the current situation of difficult analysis of critical services security situation, this paper proposes a novel service security posture awareness model (SSSA), and classifies the service data sources. The performance parameters of user quality requirements, the survivability of services themselves, Run software and hardware configuration information as an important factor affecting the trend characteristics of service posture.The feasibility of the model is verified by capturing the situation data of DNS service.Experimental results show that the model has good sensitivity to the trend of service detection and can effectively Detect deviations and failures of services and support security administrators in making the right decisions.
