  • research survey of Network Security situation awareness
    Journal of Computer Applications, 2012
    Co-Authors: Zhang Yongzheng
    Abstract:

    The research of Network Security Situation Awareness(SA) is important in improving the abilities of Network detection,response to emergency and predicting the Network Security trend.In this paper,based on the conceptual model of situational awareness,three main problems with regard to Network Security situational awareness were discussed: extraction of the elements in the Network Security situation,comprehension of the Network Security situation and projection of future situation.The core issues to be resolved,and major algorithms as well as the advantages and disadvantages of various algorithms were focused.Finally,the opening issues and challenges for Network Security situation awareness concerning both theory and implementation in near future were proposed.

  • application of fuzzy analytic hierarchy process model in Network Security situation assessment
    Computer Simulation, 2011
    Co-Authors: Wang Qingxian
    Abstract:

    The Networks are facing many Security hidden dangers,and the Network information Security is facing huge risks and Security threats.To reduce the Network Security loss,based on the analysis of the factors influencing Network Security situation,the Network Security situation assessment model was proposed based on fuzzy analytic hierarchy process method.The analytic hierarchy process was used to calculate the evaluation index weights,and the Network Security posture fuzzy hierarchical analysis evaluation model of Network Security situation was put forward.Research result shows that the evaluation model has very good scientific and practical rationality,and can improve the Network Security situation of present situation assessment.

  • a method of Network Security situation awareness based on rough set theory
    Computer Science, 2007
    Co-Authors: Wang Hui
    Abstract:

    Network Security situation awareness is a hot research field in the Network Security domain.A method of Network Security situation awareness based on rough set theory is first used,in which Network attack is regarded as the Network Security factor,and the threat degrees of each Security factor or combination of them on Network Security are analyzed quantitatively,finally Network Security situation awareness model with three layers—attacks,Network services and Security situation is established and definite Network Security situation graph is created by the simulation experiment.The use of RST makes the Network Security situation awareness system be able to deal with large volumes of Network data effectively,generate explainable attack-detection rules,then the influence of Network attack on the whole Network Security can be reflected clearly and intuitively.

  • dynamic awareness of Network Security situation based on stochastic game theory
    International Conference on Software Engineering, 2010
    Co-Authors: Liang Ying, Li Bingyang, Wang Huiqiang
    Abstract:

    Stochastic game theory is proposed to apply in the research on Network Security situational awareness (NSSA), which is a research focus in Network Security field at present. A novel dynamic awareness method of Network Security situation (NSS) based on analyses of Network service states is proposed in this paper. Realizing situation awareness is a dynamic process, and the diverse states of Network services are just direct mirrors of the whole Network Security situation. Network Security situation reflects what is happening in the Network, including both the offense and defense behaviors in it. Stochastic game model of Network Security system is constructed in this paper, and Network Security situation is quantified by the game mathematical formulation, costs or rewards of attackers and defenders are established, and finally non-linear programming is used to compute the Nash equilibrium points, at which point both of the two sides get a balance between their benefits. Network Security situation can then be dynamically achieved by visualizing the diverse metrics information of Network services at Nash equilibrium during the operating of Network system.

  • study of Network Security situation awareness model based on simple additive weight and grey theory
    Computational Intelligence and Security, 2006
    Co-Authors: Lai Jibao, Wang Huiqiang, Zhu Liang
    Abstract:

    Network Security situation awareness is a new technology to monitor Network Security, and it is one of hot research domains in information Security. The research situation of situation awareness all over the world is first analyzed. Network Security situation awareness model (NSAM) based on simple additive weight and grey theory is presented. The construction of NSAM is divided into two stages: current Network Security situation evaluation modeling and future Network Security situation prediction modeling. The model of current Network Security situation evaluation using simple additive weight is established by the threat degree of various services attacked. The model of future Network Security situation prediction adopting grey theory is built by past and current Network Security situation. Test results show that NSAM is feasible and reasonable.

  • Loose Coupling Network Security Situation Awareness Model
    Computer Engineering, 2012
    Co-Authors: Liu Bao-xu
    Abstract:

    In order to assess the historical Security states and forecasts future Network Security situation,this paper proposes a loose coupling Network Security situation awareness model by using survivability analysis based on Kaplan-Meier method.It uses survivability analysis method to get loose coupling between multi-source information fusion and Security situation awareness method.A representation analysis of example with multi-type nodes based on KDD99 is given for Security situation assessment.And it illustrates the superiority of this model in adapting the dynamic changes of Network structure and multi-source data.The applicability and correctness of model is validated by drawing the graph of Security situational awareness and comparing the results of Security situational awareness with historical Security states.
