通过对网络安全态势相关概念语义关系的分析，构建出网络安全态势的指标体系。在此基础上，利用本体工程技术，从顶级本体、领域本体、任务与行为层本体及应用层本体等四个层次，建立知识库模型。最后，对网络场景进行了形式化定义，通过网络场景来描述网络安全态势知识库中的具体实例，并分析了网络流量数据序列中的一个异常场景。
通過對網絡安全態勢相關概唸語義關繫的分析，構建齣網絡安全態勢的指標體繫。在此基礎上，利用本體工程技術，從頂級本體、領域本體、任務與行為層本體及應用層本體等四箇層次，建立知識庫模型。最後，對網絡場景進行瞭形式化定義，通過網絡場景來描述網絡安全態勢知識庫中的具體實例，併分析瞭網絡流量數據序列中的一箇異常場景。

Research on network security situational knowledge base is the basis and emphasis of research on network security situation awareness. Through the analysis of the semantic relations between concepts related to network security situation, an index system of network security situation was constructed. On this basis, a knowledge base model was formed by ontology engineering technology, from the four levels: top ontology, domain ontology, task and behavior ontology and application ontology. Finally, the network scenario was formally defined to describe the specific examples of network security situational knowledge base entity, as well as analyze an abnormal scene in network traffic time series data.
