Big Data Based on Fuzzy Grey Information System Security Intrusion Detection Research

Abstract

With the rapid development of computer networktechnology, and also can be used as well as the increasing number of users ofcomputer network, how to effectively guarantee the network information securitybecomes a key technology of computer network. This paper through the literatureinvestigation method to build the information system security risk evaluationindex system, and combining the expert evaluation process could not get all theinformation in the information system security, a method of information systemsecurity risk assessment is put forward. Was carried out on the key technologyof information system based on big data discussion and analysis, and brieflyintroduces its development prospects. Secondly illustrates the necessity ofintrusion detection, and the concept of intrusion detection and the model isgiven. Finally summarizes many kinds of intrusion detection method and thesystem structure, discusses the existing problems of this field and theresearch direction in the future.
