Research Of Real-time Network Audit Based On Data Mining

With the development of global telecommunication and the improvement of communication technology in China,information system is being widely utilized in many industries,especially in the big data era.This requires up to date auditing method and auditing skills in order to better serve as an “immune system” in every process of the national economy.Additionally,as the foundation of real time network audit,a proper method should be used for auditors to process and find valuable auditing information from the database being collected by auditing firms.This thesis,which is based on searching worldwide related reference studies,real working experience,and “real-time network audit supervision in a net” system created by T City Audit Bureau,introduces the discovery and experience of constructing auditing informatization made by T city Audit Bureau.This thesis,combining with the current condition of real time net work audit,discusses how to use the existing condition and data mining to further dig on auditing hints.At the same time,it analysis the necessity and availability of the data mining in the application in real time net work audit.Under the premise of enhancing the auditing efficiency and quality,this thesis analysis the positive result of applying auditing informatization after getting the information from data.This thesis altogether divides into five parts: The first part is introduction that introduces such contents as the topic selection background,significance,purpose,methods and framework of this research.The second part focus on analyzing two parts: one is the definition of the relevant concepts of the research,another is about the related literature review of real time net work audit and the application of data mining in some correlative fields.The third part is an overview of real time net work audit within T City Audit Bureau.Researches in thesis are all based on real time net work audit within T City Audit Bureau and then discuss the application of data mining in the real time net work audit.The forth part is to analyze the implementing environment of data mining,which introduces the construction of the system in detail.In addition,this thesis also applies support vector machine algorithm to the work of real time net work audit,and introduces theoretical basis of support vector machine algorithm and the design of experiment scheme that based on the theory.The last part points out the contributions and defects in this thesis as well as the improvement of the existing problem.Under the background of real time net work audit within T City Audit Bureau,the purpose of this thesis is to provide an example for expanding application of real time net work audit in a way of integrating data mining theory with practice.
