External terminal protection equipment and system based on one-way file transfer protocol

Abstract

The invention discloses an external terminal protection equipment and system based on a one-way file transfer protocol, and the equipment comprises a file monitoring module which is used for receivingto-be-stored data in external equipment, and transmitting the to-be-stored data to a file output module through the one-way file transfer protocol; a file output module which outputs the to-be-storeddata to a protected host according to a user instruction; wherein the one-way file transmission protocol means that the file monitoring module can only transmit encrypted to-be-stored data to the file output module, and the file monitoring module cannot transmit data to any equipment except the file output module. According to the invention, the purpose of performing safety protection on the protected host can be achieved without installing safety protection software on the protected host, the safety risk of the system is greatly reduced, and the potential safety hazard possibly generated byeach interface is comprehensively solved.

Description

technical field [0001] The invention belongs to the technical field of computer security, and in particular relates to an external terminal protection device and system based on a one-way file transfer protocol. Background technique [0002] In recent years, the rapid development of computer and network technology has greatly promoted the popularization of the network. While people are increasingly enjoying the convenience brought by the network traffic, it also provides security for the data traffic in the computers used by people in production / life. It brings new threats, such as common traffic attacks, hacker theft, unauthorized access, posing as legitimate users, destroying data integrity, interfering with the normal operation of the system, using the network to spread viruses, and man-in-the-middle eavesdropping, etc. [0003] There are many technical means to solve the problems of intranet computer network traffic control and information security, such as installing an...

AI Technical Summary

Problems solved by technology

According to statistics, 70% of computer crimes are caused by the illegal use of key resources such as hosts by insiders, and only 30% of the real threats come from outside. Irregular external equipment, implanted Trojan horse back door, resulting in abnormal data flow or even network paralysis, as well as system misoperation or deliberate destruction, will cause adverse effects or even major losses on agencies, enterprises and institutions.

[0004] At the same time, for some special equipment, such as the host equipped with special software control, the equipment of the engineer station / worker station in some industrial fields, these hosts / equipment are often not suitable for such systems on the market due to the particularity of the system. Network flow control software and security protection software, or the installation of flow control software or security software may easily cause compatibility problems with the original software of the host, or even affect performance

In addition, the hosts of these engineer stations / worker stations basically do not upgrade the operating system after they go online. Even after installing security software, they often do not update the anti-malware software version and malicious code library in time, and cannot achieve comprehensive security protection.
