Problems solved by technology

Although this method can form the "line" of the file transfer path between hosts, it is only a record of the file transfer behavior, whether the destination host successfully receives the file, and whether the file still exists on the host when an intrusion event needs to be analyzed The above problems cannot be determined by network monitoring

Embodiment Construction

[0052] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the present invention will be further detailed below in conjunction with the accompanying drawings illustrate.

[0053] The present invention provides an embodiment of a method for recording the transmission path and distribution of LAN files, such as figure 1 shown, including:

[0054] S101: monitor the creation and deletion of files on the local area network host, and record the file information of each file on the host; the file information includes: file name, file size, file format, file path and other file attribute information;

[0055] S102: Calculate the unique identifier of each file;

[0056] S103: Report the file information, the unique identifier of each file, and the hos...

Abstract

The invention provides a method and system for recording transmission paths and distribution conditions of files in a local area network. According to the method and system, host file monitoring is combined with network-level file transmission monitoring, and monitoring data are aggregated to a server for correlation analysis, and therefore, transmission paths and distribution conditions of the files between hosts in the local area network can be generated. With the method and system adopted, the defect of incapability of performing bidirectional monitoring on file transmission, accurately generating transmission paths and analyzing file distribution in the prior art can be eliminated; a basis can be provided for the backtracking of diffusion conditions of analysis files between the hosts, even if the files are deleted, the historical transmission paths of the files can be still recorded; the distribution conditions of virus files between the hosts can be obtained, and a foundation can be provided for virus elimination, and processing time can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of network file monitoring, in particular to a method and system for recording transmission paths and distribution of local area network files. Background technique [0002] With the emergence of APT (Advanced Persistent Threat, Advanced Persistent Threat) attacks, network intrusions have become more difficult to defend against. It is increasingly easy for attackers to construct targeted viruses to bypass the detection of host security software and enter the host, and can use normal software or network channels to spread in the local area network. When the security software has updated the virus database to detect virus files, it may have spread to multiple hosts in the LAN. If the transmission path of files between LAN hosts is recorded in advance and the distribution statistics are made, it can provide a basis for analyzing the process of intrusion and subsequent disposal. [0003] At present, the bounda...
