摘要:网络安全态势感知技术作为一种综合性的安全信息获取与处理技术,在网络安全防护
领域具有极其重要的地位。但是,传统的网络安全态势感知存在着准确度较低、单点失效
等方面的缺陷。云计算技术可以有效地解决节点处理能力不足的问题。文章以能处理多种
网络数据源为出发点,提出了一种基于云计算的四层网络安全态势模型,解决了网络态势
信息生成准确性的问题。同时,对节点的可信性进行了研究,使云模型具有一定的安全特
性。

Abstract: INetwork security situation awareness technology as an integrated security information
acquisition and processing technology, has an extremely important role in the field work
security. However, work security situational awareness technology has defects on
low accurate, single point of failure and other aspects. puting technology can
effectively solve the problem of insufficient processing capacity of nodes .To be able to process
variety work data sources, paper proposed a four-work security situation model
based on puting, to solve the problem work situational information generated
accuracy. Meanwhile, the credibility of the nodes was studied, so that the cloud model has certain
safety features.
Key words: Network security situation awareness; puting; Node credibility
