The embodiment of the present invention discloses a method and device for extracting user information. For the target information composed of messages, the method obtains the selected protocol extraction module according to the target communication protocol for transmitting the target information, and obtains the selected protocol extraction module from the selected protocol extraction module. Extract target protocol features from target information. Then obtain the selected user information extraction module according to the target attribute to be extracted and the target communication protocol, and extract the user information corresponding to the target attribute from the target protocol feature through the selected user information extraction module. In this method, both the protocol extraction module and the user information extraction module are pre-stored functional modules, which can generate and store a functional module for feature extraction of data transmitted through a certain protocol as required, and generate a protocol feature corresponding to the protocol. The functional module that extracts user information of a certain attribute is stored, and the stored module realizes the extraction of user information, which has good scalability.
Description
technical field [0001] Embodiments of the present invention relate to the field of network technology and information security technology, and in particular, to a method and device for extracting user information. Background technique [0002] With the rapid development of network technology and information security technology, users have become an important element of security products, and user-based audit and control have gradually become the basic functions of network security products. The premise of all this is accurate and comprehensive user information. extraction capacity. At present, the extraction of user information is based on third-party tools such as pcap to capture packets, and then the functional modules analyze the application layer protocol, and then extract the concerned attribute content. However, this method of extracting user information can only extract the information of commonly used protocols below the fourth layer, and does not have the ability t...
