Problems solved by technology

[0005] The existing technology is to analyze all the received RDP data, and the RDP data may transmit multiple data packets or only part of the data packets during one transmission, so that the received data packets can be directly analyzed Analyzing will result in extraction of wrong information
At the same time, it takes too long to analyze a large amount of data, and the time to generate logs is too slow
As a result, the audit system cannot quickly and accurately obtain user login and operation information when analyzing the generated logs, and thus cannot quickly and accurately help the audit department to complete data analysis and positioning

Embodiment Construction

[0020] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0021] figure 1 It is a flowchart of a method for parsing RDP plaintext data and log encapsulation according to an embodiment of the present invention.

[0022] In step S101, the input RDP plaintext data is processed to obtain a complete RDP plaintext data message.

[0023] In an example, the input RDP plaintext data is split and / or spliced ​​to obtain a complete RDP plaintext data message for easy parsing.

[0024] In step S102, determine the type of the complete RDP plaintext data message, and filter the RDP plaintext data message that does not require information extraction according to the type.

[0025] Specifically, the RDP plaintext data message type includes the RDP5 format data message type and the RDP4 format data message type; wherein, the RDP4 format data message includes a connection authentication phase...

Abstract

The invention relates to an RDP plaintext data analysis method and an apparatus thereof. The RDP plaintext data analysis method comprises the following steps of acquiring one complete RDP plaintext data message; then determining a type of the complete RDP plaintext data message; and finally, carrying out differential processing on the RDP plaintext data messages with different types and extracting interaction information between a client and a service terminal. In the invention, RDP plaintext data analysis time is saved, a log can be rapidly generated and a user experience is increased. The method and the apparatus can be applied to the data acquisition audit field.

Description

technical field [0001] The invention relates to the field of computers, in particular to the field of data collection and auditing. Background technique [0002] The Remote Desktop Protocol (RDP for short) is a multi-channel (multi-channel) protocol that allows a user's PC to connect to control another computer with a Windows operating system. RDP supports virtual channels to continuously transmit data exchange between the client and the server, such as display data from the server, and encrypted mouse and keyboard data on the client. The remote desktop based on the RDP protocol allows users to reliably use all applications, files and network resources on the remote computer without executing local programs. [0003] At present, the research on the RDP protocol can only be based on the technical documents related to the predecessor of the RDP protocol or the analysis of the existing rdesktop source code to obtain preliminary information, and then use the reverse engineering...
