The embodiment of the invention discloses a method and a device for extracting user information. The method obtains a selected protocol extracting module according to the target communication protocolof transmitting the target information for the target information composed of the message, and extracts the target protocol features from the target information through the selected protocol extracting module. Then, according to the target attribute and the target communication protocol to be extracted, the selected user information extracting module is obtained, and the user information corresponding to the target attribute is extracted from the target protocol features through the selected user information extracting module. In this method, the protocol extracting module and the user information extracting module are all pre-stored functional modules, A function module for feature extraction of data transmitted through a protocol can be generated and stored according to requirements, and a function module for extracting user information of a certain attribute from protocol features corresponding to the protocol can be generated and stored, and the stored module realizes the extraction of user information, which has good scalability.
Description
Technical field [0001] The 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. User-based auditing and control have gradually become the basic functions of network security products. The premise of all this is to have 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 module analyzes the application layer protocol, and then extracts the attribute content of interest. However, this method of extracting user information can only extract information from commonly used protocols below four layers. It does not have the ability t...
