A method of data centralization across security domains based on master data mapping

Abstract

The invention discloses a method for realizing data concentration across security domains based on main data mapping, which belongs to the data concentration ETL field. The method is characterized by realizing the unification of main data and business data across security domains through consistency check and map of the main data, and data integration carried out through a middleware, and comprises the following steps: through defining main data configuration, and configuring a main data sheet, fields and the referenced field information, realizing the configuration of consistency check of the main data; carrying out mapping definition of the main data and defining a data extraction rule through a main data check result, and extracting, switching and loading the data according to the main data map when the data is concentrated; and realizing data concentration from a low security domain to a high security domain through a database backup manner. Compared with the prior art, the method has the advantages that the data of different security domains can be concentrated, data sharing under the condition of physical isolation is realized, and the method has the characteristics of high security, less influence on production environment, and the like.

Description

technical field [0001] The invention relates to the field of data integration ETL (data extraction, transformation and loading), in particular to a method for realizing data concentration across security domains based on master data mapping. Background technique [0002] The problem of data exchange across different security domains is caused by the development of network security. In order to ensure the security of network information systems, the network security domains are divided for systems with different network security requirements, and network isolation is adopted for different networks. Technology, used to prevent external illegal attacks and internal data leakage. However, in the actual application of information systems, information needs to be shared and exchanged in different security domain information systems. Network isolation and data exchange are a natural pair of contradictions. At the same time, solving network security and realizing data exchange is a...

However, in the actual application of information systems, information needs to be shared and exchanged in different security domain information systems. Network isolation and data exchange are a natural pair of contradictions. At the same time, solving network security and realizing data exchange is a topic that many security technicians have been exploring. Therefore, breaking the numerous information islands caused by network security isolation has become an urgent problem to be solved.
