External terminal protection device and protection system based on file monitoring service

Abstract

The invention provides an external terminal protection device and protection system based on file monitoring service. The equipment comprises a file monitoring module which can be connected with external storage equipment and is used for carrying out safety monitoring on the external storage equipment and file data contained in the external storage equipment, wherein the file monitoring module comprises a data monitoring module, a safety file service module and a main control module, the safety file service module is used for managing and transmitting file data, and the main control module isused for controlling monitoring, management and transmission of file data; and a file output module which performs confidential data transmission with the security file service module to call securityfile data, and transmits the security file data to the protected equipment. According to the invention, the security monitoring of the external storage device and the file data contained in the external storage device can be realized, and the security risk of the protected device is greatly reduced while the secure transmission of the file data is ensured.

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 a protection system based on file monitoring services. Background technique [0002] In recent years, the rapid development of computer and information technology has greatly promoted the popularization of the network. When people enjoy the convenience brought by this computer and information technology, it is also the data in the computer used by people in production / life. Security has brought new threats, such as common unauthorized access, posing as a legitimate user, destroying data integrity, interfering with the normal operation of the system, using the network to spread viruses, and man-in-the-middle eavesdropping and so on. [0003] There are many technical means to solve intranet security problems, such as installing and using network security products such as firewalls, anti-viruses, and intrusion detectio...

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. Non-standard external storage devices, as well as system misoperation or deliberate damage, will cause adverse effects or even heavy 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. Security protection software, or the installation of 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.
