Problems solved by technology

The user needs to select the internal network or external network through the switch first, and then start the computer; or start the computer first, and then select the internal network or external network, so it takes a long time to switch between networks, which is inconvenient for users

Embodiment 1

[0029] The network selection switch 30 controls the network isolation device 20 to switch over the network through the wire control mode. When the internal network switching key 31 is pressed, the main computer 10 starts and enters the internal network mode; when the external network switching key 32 is pressed, the main computer 10 Start and enter the external network mode. If network switching is performed when the computer is running, the computer host can first save the current system running status to the hard disk, make the current system enter a dormant state, then restart the computer and switch to the network mode selected by the network selection switch. When the computer switches to the original network state again, the above-mentioned saved system operation program is automatically invoked and executed.

Embodiment 2

[0031] The network selection switch 30 is provided with a wireless transmitting module, and controls the network isolation device 20 to perform network switching through a wireless method, and the wireless method may be an infrared method or a bluetooth method. Same as the wired method described in Embodiment 1, when the intranet switching key 31 is pressed, the host computer 10 starts and enters the intranet mode; when the external network switching key 32 is pressed, the host computer 10 starts and enters the external network mode. If network switching is performed when the computer is running, the computer host can first save the current system running state to the hard disk, make the current system enter a dormant state, then restart the computer and switch to the network mode selected by the network selection switch. When the computer switches to the original network state again, the above-mentioned saved system operation program is automatically invoked and executed.

Embodiment 3

[0035] In order to further facilitate the operation of network switching, the present invention can set the network selection switch 30 on the computer host 10 , and embed the internal network switching key 31 and the external network switching key 32 on the boot panel of the computer host 10 . Different from the traditional computer mainframe, the computer mainframe has two power-on keys with both network switching functions—intranet switch key 31 and external network switch key 32 . When the intranet switch key 31 is pressed, the computer host 10 starts up and enters the intranet mode; when the extranet switch key 32 is pressed, the computer host 10 starts up and enters the extranet mode. If the network switch is performed when the computer is running, the computer host can first save the current operating state of the system to the hard disk, make the current system go to sleep, then restart the computer and switch to the network mode selected by the network selector switch....

Abstract

The isolation system for computer and network includes following parts: host of computer; network isolation device (NID) is connected to the host of computer, and network interface of NID is connected to inner network and outer network respectively; and network selection switch (NSS). Through wired or wireless modes, network selection switch communicates with NID. Inner network switch key (INSK) and outer network switch key (ONSK) are setup on NSS. Carrying out network switching, INSK and ONSK starts computer at same time. Characters of the invention are that functions for switching networks and starting computers are integrated on one key to implement switching network in mode of 'one key in type'. Moreover, the invention also can implement sleep-switching mode. The invention raises speed for switching network effectively, and is convenient to use.

Description

technical field [0001] The invention relates to a network isolation technology in the field of computer network information security, in particular to a network isolation system applied to a computer network and a control and switching method thereof. Background technique [0002] With the rapid development of computer technology and the widespread popularization of the Internet, network security and information security have become an issue of increasing concern, especially in government agencies, banks and other enterprises and institutions, whose internal confidential or confidential data information is not It is hoped to be freely obtained by users of external networks. Once important data is leaked, it will cause great losses to the interests of the unit or company, and even threaten the security and interests of the country. In order to solve the above problems, a network isolation technology has emerged. There are various forms of existing network isolation methods, a...
