This paper introduces the cloud computing technology to the digital forensics problem with the network traffic as the goal, firstly, the background knowledge of cloud computing and the background knowledge of digital forensics are introduced briefly. The advantages of Hadoop2.2 and the reasons of choosing this version as the base platform are emphatically described. Secondly, it expounds the architecture of map-reduce and yarn, gives the digital forensics model of network traffic based on cloud computing, sums up the distributed SVM algorithm, and puts forward an improved distributed SVM algorithm based on previous algorithms. As a network traffic algorithm, the validity and accuracy of the method are verified experimentally, and the experimental process and results are given, which proves that the distributed algorithm can improve the efficiency and performance of traffic analysis to some extent under the premise of guaranteeing the accuracy. Finally, the work of this paper is summarized, The paper also forecasts the background of digital forensics applied in cloud computing.
