Method and device for improving safety of data interaction between enterprises

Abstract

The invention discloses a method and device for improving safety of data interaction between enterprises. The device is arranged in a DMZ space deployed between an enterprise intranet and an externalnetwork. The device comprises an MQ module used for organizing external incoming data in a message queue mode; a preprocessing module used for sequentially preprocessing the data organized by the message queue, wherein preprocessing comprises data cleaning, data integration and data transformation; and a CDC module used for synchronizing the preprocessed data flow to an enterprise intranet database in real time by adopting a changed data capture mode. According to the device and the method, high security and high stability of data exchange between enterprises are improved.

Description

technical field [0001] The invention relates to the field of communication security, in particular to a method and device for improving the security of data interaction between enterprises. Background technique [0002] The degree of informatization of existing enterprises is gradually improving, and more and more information systems are used within the enterprise. The specialized systems used by each production unit in the industrial chain operate independently, each producing and managing a certain amount of data. There is no direct relationship between these data, but as an information-based industrial chain, data flows in every link. Data is now an important production resource, making the entire industry operate as a whole. [0003] There is actually an inherent logical connection between the data within each production unit. If a complete business process is realized across units, it often requires the cooperation of multiple information systems of each unit. These d...

Problems solved by technology

However, this often means a huge development workload and maintenance costs, because ensuring data security requires a lot of manpower for system security construction and may affect the efficiency of information transmission. Carry out effective combing and screening to avoid table lock and data redundancy caused by repeated reading, writing and modifying of the database

If a dedicated conversion application is established for each different application database storage, the development complexity will be very large and the development cycle will be very long

However, in the existing technology, it is difficult to have a system that satisfies safety and reliability and can effectively sort out the program. The development cost is high, more maintenance costs are required, the development cycle is long, and various factors need to be involved. In practice, There will also be various problems, resulting in a low success rate of software system development and a long development cycle, which is not conducive to the implementation of enterprise projects
