    摘要:

    随着Internet规模的迅速扩大,复杂性和不确定性也随之增加,基于融合的网络态势感知必将成为网络管理的发展方向.在分析现有网络管理不足以及发展需求的基础上,介绍了网络态势感知的起源、概念、目标和特点.首先,提出了一个网络态势感知研究框架,介绍了研究历程,指出了研究重点以及存在的问题,并将现有评估方法分为3类:基于数学模型的方法、基于知识推理的方法、基于模式识别的方法.然后详细讨论了模型、知识表示和评估方法这3方面的研究内容,总结存在的共性问题,着重评价了每种评估方法的基本思路、评估过程和优缺点,并进行了对比分析.随后介绍了网络态势感知在安全、传输、生存性、系统评价等领域的应用研究.最后指出了网络态势感知的发展方向,并从问题体系、技术体系和应用体系3方面作了总结.

    Abstract:

    The rapid development of Internet leads to an increase in system complexity and uncertainty. Traditional network management can not meet the requirement, and it shall evolve to fusion based Cyberspace Situational Awareness (CSA). Based on the analysis of function shortage and development requirement, this paper introduces CSA as well as its origin, conception, objective and characteristics. Firstly, a CSA research framework is proposed and the research history is investigated, based on which the main aspects and the existing issues of the research are analyzed. Meanwhile, assessment methods are divided into three categories: Mathematics model, knowledge reasoning and pattern recognition. Then, this paper discusses CSA from three aspects: Model, knowledge representation and assessment methods, and then goes into detail about main idea, assessment process, merits and shortcomings of novel methods. Many typical methods are compared. The current application research of CSA in the fields of security, transmission, survivable, system evaluation and so on is presented. Finally, this paper points the development directions of CSA and offers the conclusions from issue system, technical system and application system.
