Abstract

The utility model relates to a unidirectional physical isolation type network safety device which belongs to the field of network safety and solves the contradiction between the absolute safety protection of an internal network and the unidirectional data transmission from the internal network to an external network. The utility model is characterized in that a closed computer case with an internal computer outwards provides only one network input port and one network output port which are respectively connected with the internal network and the external network. By a network driving stage unidirectional control technology and that an output network cable of the network input port and an input network cable of the network output port in the computer case are cut off, unidirectional complete isolation from any connection with the external network can be realized; meanwhile, the function of the unidirectional data transmission from the internal network to an external network can also be realized; the security check, filtrating and parsing of application layer data is once again packaged additionally in an export technology. The innovative design of full-solidified idiot-type plug-and-play which is free of management and misoperation additionally increases the safety; the utility model is suitable for the situations of the unidirectional data transmission and that the highest safety is required to the internal network, such as a production control system transmits production real-time data to a management information system.
本实用新型是一种单向物理隔离型网络安全装置,属网络安全领域。解决了“要保障内网绝对安全”和“内网数据单向向外网传输”间的矛盾。其主要特征是,一内装计算机的封闭机箱,对外仅提供一网络输入口和一网络输出口,分别连接内网和外网。机箱内部通过将输入口的输出网线切断和将输出口的输入网线切断及网络驱动级单向控制技术,实现单向完全隔断同外网的一切连接,同时可实现从内网到外网的单向数据传输功能;应用层数据的安全检查过滤解析重新另封装输出技术、创新的全固化免管理的“傻瓜型”即插即用、防误操作设计,更增加了安全性。适用于单向数据传输且对内网安全有最高要求的场合,如生产控制系统向管理信息系统传输生产实时数据。
