Abstract

The utility model provides a computer safety device capable of achieving network physical isolation, and the computer safety device capable of achieving network physical isolation is good in isolation effect and high in safety. The computer safety device capable of achieving network physical isolation comprises a network security separate card, a network interface, a power interface, an intranet processor, a safety hard disc, an extranet processor, an internet accessing hard disc, a switcher and a self-adaption encipher, wherein the switcher is arranged on the network security separate card, the network security separate card is provided with the network interface and the power interface, the safety hard disc and the self-adaption encipher are connected with the intranet processor, the internet accessing hard disc is connected with the extranet processor, and the intranet processor and the extranet processor are connected with the switcher. Due to the fact that the self-adaption encipher is added, a user needs to input intranet starting pass words when an extranet is switched to an intranet, the self-adaption encipher is triggered and a computer conducts self-locking, when no operation is conducted within one minute, the cache is wiped and an intranet power supply is shut down when the condition that the pass words are not correctly input for more than three times is fed back to the intranet processor, and intranet safety is enhanced.

Description

A kind of computer security device of realizing the network physical isolation

Technical field

The utility model relates to computer safety field, relates in particular to a kind of computer security device of realizing the network physical isolation.

Background technology

the security assurance information ability is new century national overall national strength, the important component part of white war strength and viability, especially in government network, internal network has a large amount of sensitive information, constantly realizing informationization, in the time of efficient convenient information, safe and secretly also be even more important, but the safety assurance ability of information network lags behind its development far away, the form severe of information security, only make in-house network and public network physical isolation, could guarantee really that the internal information network is not subjected to the assault from internet, physical isolation also delimited clear and definite secure border for in-house network, make the controllability of network strengthen, be convenient to inner management, in existing physical isolation card only guarantees, the information of outer net is fully independent, do not share, in switching, computer meeting autoboot during outer net, and automatically remove buffer memory, in making, the outer net hard disk is not altered mutually, but perfect not for the Intranet function of keeping secret, when the computer unmanned, if someone opens computer, can directly enter Intranet, steal capsule information.

Summary of the invention

according to above technical matters, the utility model provides a kind of isolation effect good, the computer security device of the safe network physical realized isolation, comprise isolation card, network interface, power interface, interior network processor, safe hard disk, outer network processor, the online hard disk, switch, it is characterized in that: also comprise the adaptive refinement device, described switch is arranged on isolation card, described isolation card is provided with network interface and power interface, described network interface has three, connect respectively the computing machine network interface card, Intranet, outer net, described power interface has three, connect respectively the computer motherboard power supply, safe hard disk power supply, online hard disk power supply, described safe hard disk, the adaptive refinement device is connected with interior network processor, described online hard disk is connected with outer network processor, described interior network processor, outer network processor is connected with switch.

the beneficial effects of the utility model are: the utility model has increased the adaptive refinement device on original basis, when the user switches to Intranet from outer net, the Intranet setting up password that needs input to set, prevent that the stranger from stealing confidential data, when the user switches to Intranet from outer net, the Intranet setting up password that needs input to set, prevent that the stranger from stealing confidential data, when computing machine is in the Intranet pattern, without any operation over one minute, can trigger adaptive refinement device self-locking computer, when inputting the password mistake over three times, can feed back to interior network processor, remove buffer memory, and network source in cutting off, strengthened the security of Intranet, Inside and outside network has fully independently storage hard disk, more effectively realize the physical isolation of network.
