Research And Implementation Of Network Attack Effect Evaluation

With the rapid development of network and the Internet,network security has gradually become a great hidden danger for the threat to the country and the people,network security greatly affected the national development and people's life,the network security in various fields has received some attention,in the field of national defense,space network,the network operational concepts are gradually accepted by everybody.Network space against technology and equipment development,the urgent need for quantitative and qualitative assessment of the network attack effect,used to guide the development of network attack weapons and find their own vulnerability.This paper is focused on the construction of the two main problems index system and the evaluation model of the network attack effect evaluation.The main work of this paper includes the following aspects:1)each kind of network attack should be corresponding to the evaluation index,according to the index extraction principles,from three aspects of system,network and network attack type,constructed a comprehensive network attack effect evaluation index system,at the same time,the paper analyzes the index system of the rationality of the evaluation criteria and the scalability problem.2)in order to establish the network attack effect evaluation model,this paper studies the standardized method of the index data,index weight calculation,research and analysis of the entropy weighting method to determine the weight of the principle,and gives the calculation process,and compares the advantages and disadvantages of the AHP and Fuzzy AHP,analysis of Fuzzy AHP to determine the weight computation process.Based on the establishment of evaluation index system,the research and analysis of various evaluation methods,the establishment of the evaluation model.Also introduced fuzzy evaluation method,using the fuzzy comprehensive evaluation of attack effect evaluation,and through an example,a complete analysis of the calculation of the specific process of evaluation model of fuzzy analytic hierarchy process(AHP)and fuzzy comprehensive evaluation method combining based on evaluated.3)based on the above research,the design and implementation of the a set of index information collection,index data show and network attack effect evaluation calculation of the prototype system,described in detail the system design and each module,the prototype system of data acquisition based on open source software,data processing,calculated using the python language,effect evaluation uses the Django framework to build the website shows.
