Research And Implementation Of Targeted Object Attack Evaluation

With the rapid development of the network,the Internet has become a high-performance computer network.However,network communication,resource sharing and other characteristics have brought convenience to the illegal elements,and network security events occur frequently.With the development of network security,information security is not only about defense,detection,control,management and so on,but now it has been extended to attack,analysis and evaluation.The research and analysis of the target state after network attack and the accurate and effective evaluation of the attack results have become an important research content in the process of network development and network security construction.By studying the evaluation of the attack effect,we can measure the safety of the device,in order to make the information system able to deal with many kinds of sudden attacks in complex and changeable network environment,so as to improve the compression ability and viability of the information system.In addition,the information data in the evaluation process provide data support and defense basis for information security and intrusion detection.This paper focuses on the evaluation technology of network attack effect.Combined with the existing index system,by analyzing the characteristics of attack targets,we first set up a set of evaluation criteria for target parties,and set up the three levels index system of "target attribute index".Through comprehensive analysis,research and extraction of the attributes that are changing before and after the attack of the target side,a comprehensive evaluation system of the network attack effect of the surface object is established.Secondly,the concept of fuzzy trend approaching degree is put forward.The closeness degree between fuzzy AHP and entropy weight is regarded as the basis of weight accuracy,and the fuzzy hierarchical weight trend is used as the benchmark to determine the weighting method.Using the comprehensive evaluation method is proposed in this paper and multiplied the proximity of the comprehensive weight were weighted calculation,compared to the use of different methods of influence on the results,and explain the influence of different weights and evaluation results closer to the accurate weight of fuzzy trend and as a follow-up assessment to determine the way.Into the TOPSIS method based on grey relational concept weights,evaluation and calculation in Euclidean distance sequence with the desired sequence of join index mutual influence degree consideration so as to establish close comprehensive correlation weighted TOPSIS evaluation method based on the solution,and the positive and negative ideal sequence set the elimination of the sample data or re set the reference sequence of complex process.Finally,we design and implement a target attack oriented network attack effectiveness evaluation system,and introduce the overall design plan and core module design and implementation.Through the experiment,the evaluation model is validated effectively.
