[0002] The security protection of the core data server is an issue that every unit that owns a data publishing server attaches great importance to. Existing protection measures such as firewalls, security certification and other software methods are used for security protection. This single software protection measure is still vulnerable to destructive power. Trojan horse virus invasion

Embodiment Construction

[0012] As shown in the figure, a switch 2 is connected between multiple data distribution servers and the core data server 1, and each data distribution server has a fixed IP address, which is published to the public network through a router 12. This is the prior art, and this embodiment Among them, four data publishing servers 3, 4, 5, and 6 are used. Timing relays are connected between each data distribution server and the router, and the four data distribution servers 3, 4, 5, and 6 are correspondingly connected with timing relays 7, 8, 9, and 10. Each data publishing server is connected to the corresponding timing relay, and each timing relay is connected to the router 12 through a network cable. Between each data publishing server and the corresponding timing relay, between each timing relay and the router, a network cable is connected through a crystal head connector. One end of the network cable is also connected with a crystal connector, and the aforementioned two cry...

Abstract

The invention relates to a network safety protection physics isolation apparatus and a method thereof. The apparatus comprises: a core data server, a plurality of data release servers and a router. A switchboard is connected between a plurality of data release servers and the core data server. A timing relay is connected between each data release server and the router. The timing relays close alternatively and only one timing relay closes at a time. And correspondingly, each data release server updates data for the core data server alternatively. Each time only one data release server updatesthe data for the core data server so that an IP address published on a public network changes continuously.

Description

technical field [0001] The invention relates to a physical isolation device and method for network security protection. Background technique [0002] The security protection of the core data server is an issue that every unit that owns a data release server attaches great importance to. Existing protection measures such as firewalls, security certification and other software methods are used for security protection. This single software protection measure is still vulnerable to destructive power. Trojan horse virus intrusion. Contents of the invention [0003] The object of the present invention is to provide a physical isolation device and method for network security protection, which can effectively improve the network security of a core data server. [0004] Based on the same inventive concept, the present invention has two independent technical solutions: [0005] 1. A physical isolation device for network security protection, comprising a core data server, multiple ...
