基于云計算的數(shù)字取證關(guān)鍵技術(shù)的研究與實現(xiàn)
[Abstract]:Now, the network has become one of the most important roles in people's life, at the same time, a variety of security problems have emerged. In this context, digital forensics for the network has become a hot spot. At the same time, the rise of cloud computing technology provides a new solution to the problem of digital forensics. The ability of cloud computing technology to solve large-scale data is obvious. This new technology has provided a new form of computing and storage services. In this paper, cloud computing technology is introduced into digital forensics with network traffic as its target. Firstly, the background knowledge of cloud computing and the background knowledge of digital forensics are briefly introduced, and the advantages of Hadoop2.2 are described emphatically. And the reasons for choosing this version as the base platform; Secondly, the architecture of map-reduce and yarn is expatiated, and the network traffic digital forensics model based on cloud computing is given, and the distributed SVM algorithm proposed by predecessors is summarized, which is based on the previous algorithms. An improved distributed SVM algorithm is proposed as a network traffic algorithm. The validity and accuracy of the algorithm are verified by experiments, and the experimental process and results are given. It is proved that this distributed algorithm can ensure the accuracy of the algorithm. Improve the efficiency and performance of flow analysis to a certain extent; Finally, the work of this paper is summarized, and the application of cloud computing digital forensics background is prospected.
