摘　　要：建立了网络安全态势感知的分层实现模型,并针对每个层次提出了基于多分类器融合的安全态势提取方法、基于统计学习的分层态势评估方法以及基于遗传神经网络态势的动态预测方法。经仿真实验验证,每个层次的实现方法都是可行有效的。Network security situation awareness technology is a novel technology to defend attacks and intrusions and provide global network security situation in an active and real-time style. The hierarchical realization model of network security situation awareness is built. The corresponding realization method of each layer is put forward respectively, including network security situation element extraction based on multi-classifier fusion, hierarchical situation assessment based on statistical learning and dynamic situation prediction based on back propagation neural network with genetic algorithm. Experimental results show that the proposed realization methods are feasible and reasonable.
