An electronic document output control system and method based on one-way transmission

Abstract

The invention provides an electronic document output control system and method based on one-way transmission. The system includes: a terminal agent module, a centralized management center module, and an outgoing isolation module. The terminal agent module communicates with the centralized management center module in two directions; the centralized management center module Two-way communication with the outgoing isolation module; the advantages are: (1) Through the one-way transmission technology, the internal network is connected to the peripheral output device through the outgoing isolation module, ensuring the one-way output of electronic documents, and realizing the output of peripheral devices such as printers Effective isolation from sensitive internal networks; (2) Ensure the credibility of the outgoing source of electronic documents through secure identity authentication, ensure that the content of outgoing electronic documents is manageable and controllable through security checks, and ensure that only authorization is granted through the implementation of security policies (3) It supports multiple output methods such as print output, CD burning output, and storage medium output, and can be widely used in various electronic document security output occasions.

Description

technical field [0001] The invention belongs to the technical field of network information security, and in particular relates to an electronic document output management and control system and method based on one-way transmission. Background technique [0002] In the modern enterprise office environment, there are a large number and various types of electronic documents. Among them, electronic documents refer to documents that rely on computer systems to access and can be transmitted on communication networks, including: electronic documents, electronic letters, electronic reports, and electronic drawings. , electronic versions of paper text documents, etc. Due to work needs, the demand for outputting electronic documents is very common. Here, electronic document output includes two types: (1) printing electronic documents as paper documents by printers: for example, printing electronic documents as paper documents, and then, Hand over the printed paper documents to the le...

Problems solved by technology

[0003] The existing electronic document output method is mainly: each employee is equipped with a terminal computer for office use, and the employee directly outputs electronic documents through various peripheral interfaces configured on the terminal computer. The main problems of this output method are: (1) output Behavior is uncontrollable: the output behavior of employees outputting electronic documents cannot be monitored, and once a leak occurs, it cannot be tracked and traced; (2) output content is uncontrollable: the content of electronic documents output by employees cannot be monitored, which may easily cause information leakage; (3 ) output devices are uncontrollable: printers and other output devices on the market have independent chips, and there is a risk of actively accessing and attacking the internal network of the enterprise, thereby stealing corporate information; And send it out through the built-in wireless module of the printer settings, resulting in information leakage
