Research And System Realization Of Security Situation Evaluation In Enterprise Intranet

In recent years,with the continuous development of Internet technology and the expansion of computer networks,the traditional security technology meets difficulties in solving the threatens of various types of different networks,the network security situation assessment has been invented as an independent security mechanism in this situation.The network security situation assessment can extract the safety factors from various kinds of massive safety related data,construct the evaluation index system,evaluate the network security situation objectively and accurately and provide valuable help to network managers in making the correct safety protection decisions.Due to the lack of classification for different network types in the present situation,the accuracy of assessment of catholicity network security situation model and index system has reduced in special network conditions.In view of the above problems,this paper focuses on the research and realize the system of the security situation assessment of the special network type of the intranet of enterprise,which mainly includes the following specific aspects:(1)Comparing the basic models and methods of the current security situation assessment,combining with the network structure characteristics and practical application requirements of the enterprise network,according to the theory of analytic hierarchy process,from the three aspects of assets,vulnerability and threat,Hierarchical enterprise network security situation assessment model and index system has been constructed(2)According to the norms and standards of various safety assessment,the index of the index system is quantified and the method of constructing the bias judgment matrix is used to divide the index weight and the calculation of the security situation value.Finally,obtain the results of the security situation assessment and verified the scientificity of the calculating method by means of experiment(3)On the basis of this,the enterprise security situation evaluation system including data acquisition,environmental testing,situation assessment,security situation displays and early warning function module is realized by means of system development tools such as Microsoft Visual Studio 2010 development platform.
