Embodiment 1

[0059] Please refer to figure 1 , 3 , a kind of electronic forensics method of present embodiment, comprises the steps:

[0060] S1. The edge node receives the electronic data forensics task issued by the cloud platform, and issues the electronic data forensics task to the corresponding forensics equipment;

[0061] Specifically, the sending the electronic data forensics task to the corresponding forensics equipment includes:

[0062] The edge node decomposes the electronic data forensics task into multiple subtasks, and sends the subtasks to corresponding forensics devices according to preset rules;

[0063] Among them, the preset rules include file type processing rules, file size processing rules, content element processing rules, file source processing rules, file metadata processing rules, source application type processing rules, etc.;

[0064] For example, when a user initiates an electronic data forensics task on the cloud platform, he first enters basic information...

Embodiment 2

[0079] Please refer to Figure 4 , 5 , on the basis of Embodiment 1, this embodiment further defines how to build the three-layer architecture of the cloud edge terminal and how to configure the functions of each layer of the cloud edge terminal before step S1:

[0080] Including the construction of a cloud-side-end three-tier architecture;

[0081] Specifically, as Figure 4 As shown, edge nodes are added to the cloud platform and forensics equipment to realize the cloud-edge-end three-tier architecture. The edge nodes are deployed in the electronic data forensics laboratory. One cloud platform manages multiple edge nodes, one edge node manages multiple forensics equipment, and the cloud The platform and the edge nodes are connected by a backbone network, and the edge nodes and forensics equipment are connected by a 10G LAN to ensure bandwidth capacity;

[0082] Configure the functions of each layer of the cloud edge;

[0083] like Figure 5 As shown, the cloud platform ...

Embodiment 3

[0087] Please refer to figure 2 , an edge node for electronic data forensics, including a memory, a processor, and a computer program stored on the memory and operable on the processor, and implementing the first or second embodiment when the processor executes the computer program each step in the .

[0088] To sum up, the electronic data forensics method and the edge node provided by the present invention receive the electronic data forensics task issued by the cloud platform through the edge node, decompose it into multiple subtasks, and issue the subtasks according to preset rules To the corresponding forensics equipment, the sub-tasks are coordinated to improve the timeliness of data processing. The edge node receives and stores the structured data collected by the forensics equipment, gathers the structured data to the cloud platform, and then receives the unstructured data and based on The preset task processing strategy is used for calculation, and the calculation re...

Abstract

The invention discloses an electronic data forensics method and an edge node, and the method comprises the steps: receiving an electronic data forensics task transmitted by a cloud platform through the edge node, transmitting the electronic data forensics task to corresponding forensics equipment, receiving original data collected by the forensics equipment, and calculating unstructured data in the original data; gathering the obtained calculation results to the cloud platform, and newly adding the edge nodes between the cloud platform and the forensics equipment to form a cloud edge end three-layer architecture, so that even if the backbone network or the cloud platform fails, the transmission between the edges and the ends is not influenced, and the stability of data transmission is improved; moreover, the cost for local construction of the architecture is lower than that of a cloud platform and a data center network structure, the construction cost is reduced, unstructured data in original data is calculated through edge storage and edge calculation technologies, obtained calculation results are gathered to the cloud platform, a user can analyze the calculation results on the cloud platform. And full application of the unstructured data is realized.

Description

technical field [0001] The invention relates to the field of electronic data forensics, in particular to an electronic data forensics method and an edge node. Background technique [0002] Electronic data forensics has gone through three eras, and the period from 2001 to 2011 belongs to the first generation, which is characterized by single-soldier media forensics and no data aggregation. The period from 2012 to 2017 belongs to the second generation, and its main feature is the construction of a cloud platform, which realizes the aggregation and comprehensive analysis of electronic data. Currently entering the third generation, the main features are artificial intelligence applications, cloud forensics, Internet of Things forensics, etc. At present, there are basically two layers of architecture - cloud and end, where cloud refers to the cloud platform, and end refers to electronic forensics equipment. Forensics data mainly gathers structured data, and most cases do not ga...
