网络安全态势感知综述

网络安全事关国家安全和经济社会稳定，网络安全态势感知作为一种高效智能的新时代网络安全防护体系，正在得到中外学者的高度关注和广泛研究。从态势感知的发展历程和相关概念出发，对网络安全态势感知的现有研究进行了梳理与对比，根据一种基于数据融合的网络安全态势感知框架，总结分析了网络安全态势提取、网络安全态势评估、网络安全态势预测3个层面的主要技术优缺点，并据此对其未来发展方向进行了分析与展望。

Overview of Network Security Situation Awareness

Network security concerns national security and social stability. As an efficient and intelligent protection system for network security in the new era, network security situation awareness is increasingly receiving great attention and extensive research from foreign and domestic scholars. From the development history and related concepts of situation awareness, existing studies on network security situation awareness are sorted out and compared. Meanwhile, according to a framework of network security situation awareness based on data fusion, the advantages and disadvantages of main technologies are analyzed and summarized from the three perspectives of extraction, assessment and prediction of network security situation. On this basis, the direction of its development in the future is analyzed and prospected.
