Embodiment Construction

[0039] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0040] In related technologies, it is possible to obtain network traffic during network use through tools such as a data leakage prevention (DLP) client, and determine whether the network traffic satisfies a specified condition. When the network traffic satisfies the specified condition, it is determined to use The network transferred the file. However, the judgment granularity of this method is low, and it cannot be accurate to the file level. Usually, the transmission operation of request information (such as the request information for opening a web page) is misjudged as a file transmission operation. Therefore, the accuracy of this detection method is relatively low. Low. Moreover, when the request information is intercepted...

Abstract

The application discloses a file transmission detection method and device, and a storage medium, belonging to the field of network technology. The method includes: obtaining the first data set through the network filter driver in the operating system, and the first data set includes: a plurality of first data transmitted through the network; obtaining the second data through the file filter driver in the operating system set, the second data set includes: a plurality of second data in the file that has been operated, and the second data is used to characterize the file content of the file that has been operated; when the first data set and the second data set have the same When the target data is selected, the file to which the target data belongs is determined as a file that has been transmitted through the network. The application effectively improves the detection accuracy.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a file transmission detection method and device, and a storage medium. Background technique [0002] With the rapid development of Internet technology, people pay more and more attention to information security. Among them, enterprises are particularly concerned about the information security of confidential materials such as technical documents of enterprises. Usually, when detecting whether an employee transmits confidential information to the outside of the enterprise, it is necessary to first detect whether the file is transmitted through the network. [0003] In related technologies, it is possible to obtain network traffic during network use, and determine whether the network traffic satisfies a specified condition, and when the network traffic satisfies the specified condition, it is determined that the file is transferred using the network. Wherein, the network traffic...
