Embodiment Construction

[0051] This embodiment adopts xml configuration file to store data structure information, filtering rules and merging rules. In the data structure information, in addition to setting attributes such as field type, name and size for each field of the data, an offset needs to be set The offset (offset) attribute is used to indicate the offset of the field relative to the starting position of the data it belongs to in the memory. The field value is obtained by the starting position of the data in the memory and the offset of a certain field of the data , to filter and merge data.

[0052] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0053]In order to realize data filtering and merging, it is necessary to define data structures, filtering rules and merging rules for various types of data, and store the structural information, filtering rules and merging rules of the same type of data in a configuration file....

Abstract

The invention discloses a data filter and combination method, comprising: storing the structure information, the filter rule and the combination rule of data in the corresponding configuration file according to the data types; after receiving the data, reading the corresponding configuration file according to the received data type and removing by filtration or keeping the data according to structure information and filter rule in the read configuration file; if the data is kept, combining the data with relative data according to the structure information and the combination rule in the read configuration file. The invention, by using the configuration file to store the structure information, the filter rule and the combination rule of data in various types and reading the corresponding field value through the field offset and the initial position of the data in the memory, carries out data filter and combination, so as to enhance the system flexibility.

Description

technical field [0001] The invention relates to the technical field of information management, in particular to a data filtering and merging method. Background technique [0002] Security Information Management (SIM) technology is used to collect, analyze and correlate security event information from the entire enterprise. Security information management technology specifically refers to collecting and analyzing security event information, detecting security events in a timely manner, and taking corresponding network security management measures. For the detected security events, according to the needs of the user, it is necessary to filter and combine them according to different field values. [0003] SIMS (Security Information Management System, SIMS) needs to collect various types of data such as logs and alarm data of various security devices, network devices, hosts, and application systems, and the types of various data are different. At present, the main method of da...
