the file log comprises an operation log and a process exit log;
the file operation request at least comprises one of the following: file creation requests, file read requests, and file write requests.
In this embodiment, before filtering the obtained file logs, file logs of various files are further obtained. For example, the file filtering driver may obtain a file creating request, a file reading request, and a file writing request sent by the process, generate an operation log according to the file operation request of the process, and register a callback function in the file filtering driver to monitor the process exit operation, thereby obtaining the process exit log, and thus obtaining a complete file log, that is, the file log includes an operation log and a process exit log.
In an embodiment, the filtering the obtained file log to obtain an associated log of the compressed file includes:

when the file suffix is determined to be a specified compressed suffix, recording the file read log;
the specified compression suffix comprises the following compression format: zip, rar, 7z, cab, and tar.
In this embodiment, the file log is filtered to screen out the associated log of the compressed file. For example, in a case where it is determined that the operation log includes a file read log, a file suffix of a file read by the file read log may be detected, and when it is determined that the file suffix is a specified compressed suffix, the file read log may be recorded. The file suffix referred to in this embodiment is a compressed package file suffix, and the compressed format may be zip, rar, 7z, cab, and tar, or may be other compressed formats, which is not limited herein. Of course, if the file suffix of the file read by the file read log is detected in the case where it is determined that the operation log contains the file read log, as shown in fig. 2, if the detected file suffix is not the specified compressed suffix, no processing is performed.
In an embodiment, the determining, according to the association log, an operation behavior performed on the compressed file, and recording the operation behavior according to a preset rule includes:

And recording the log if the process ID and the thread ID of the file creation log are the same as the process ID and the thread ID of the recorded file read log of the compressed file. For example, a file read log of a compressed file may be stored in association with a corresponding file creation log. If the file read log recorded by the same process ID and thread ID does not exist, the processing is not carried out.
In an embodiment, the determining, according to the association log, an operation behavior performed on the compressed file, and recording the operation behavior according to a preset rule further includes:

The specific file write log records a process ID for performing a write operation, a thread ID, and a file name for the write operation to be performed. For example, in this embodiment, the process ID, the thread ID, and the file name of the file write log may be compared with the process ID, the thread ID, and the file name of the file creation log, and as shown in fig. 2, if the process ID, the thread ID, and the file name are the same, the file write log is recorded. For example, a file write log of a compressed file may be stored in association with a corresponding file creation log. If the file write log recorded by the same process ID, thread ID and file name does not exist, the processing is not carried out.

and under the condition that the comparison results are the same, generating a decompression log according to a preset file compression rule.
In this embodiment, the process ID in the process exit log and the process ID in the file creation log are further compared, and in the case that the comparison result is the same. That is, this indicates that the compressed file that performed the file creation step has completed subsequent operation actions. In this embodiment, after the process exits, the decompression log is generated according to the preset file compression rule under the condition that the comparison results are the same. Thus, the decompression log of the compressed file can be obtained.
In an embodiment, the generating a decompression log according to a preset file compression rule includes:
and under the condition that the operation log contains a file write log corresponding to the current process exit log, matching the file write log and the corresponding associated record result according to a preset algorithm to obtain a decompression log.

Thus, it is determined that the write operation is performed on the compressed file, and thus the file write log and the corresponding associated record result may be matched according to a preset algorithm in this embodiment, so as to obtain a decompression log. For example, the file write log, the file read log of the associated record and the file creation log are matched according to a preset algorithm, so that a decompression log is obtained. In an alternative embodiment, the obtained decompression log may be named according to a file name of the corresponding file read log. Therefore, the problem that the compressed file in the process cannot be tracked is solved, and the tracking of the data flow of the compressed file is realized. And if the operation behavior of the compressed file comprises a file creation log, and the process is executed and exited under the condition that the operation behavior of the compressed file does not comprise a file writing log, the process is not recorded.
