Abstract
The utility model discloses a computer network security isolation system, including that auto -change over device connects intranet and outer net through the main frame of service isolator connect switch device, being equipped with ordinary hard disk parallelly connected each other, excessive hard disk and main hard disk in the main frame, connect first switch between ordinary hard disk and the excessive hard disk, connect the second switch between excessive hard disk and the main hard disk, ordinary hard disk, excessive hard disk and main hard disk are through first switch and second switch linked computers power, service isolator and auto -change over device linked computers power. The utility model discloses an advantage: the utility model discloses inserting outer net computer -chronograph host computer and working with single hard disk mode, can in time cut off the data transmission between intranet and the outer net when meetting the network risk, be three hard disk mode with the main frame switching simultaneously, ensured the intranet information security, auto -change over device connects alarm device, can play the effect of warning illegal invasion, has stopped the possibility that information was revealed.
Description
Technical field
The utility model relates to computer realm, particularly relates to a kind of computer network security shielding system.
Background technology
Along with the progress of computer technology, computing machine is with its exclusive function and powerful ability to work, and computing machine has become the necessary instrument of people's life and work.For any computer network, network security and information security have become a problem day by day received publicity, the particularly Intranet of some unit, enterprise, in-house foundation and private, must cannot invade by strict guarantee internal network, internal data does not leak, simultaneously not by the virus on internet, wooden horse infect, once there is information leakage, can suffer heavy losses to the interests of our unit.Existing information security of computer network is poor, and computing machine is not easy to management, causes sensitive information leakage, especially shows the aspect such as to steal of Internet resources, causes great impact to the use of computing machine.
Utility model content
The purpose of this utility model is to solve the shortcoming existed in prior art, and a kind of computer network security shielding system proposed.
To achieve these goals, the utility model have employed following technical scheme:
A kind of computer network security shielding system, it is characterized in that: comprise main frame, described main frame Connection Service isolator, described service isolator connection switching apparatus, described switching device shifter connects Inside and outside network, common hard disc parallel with one another is provided with in described main frame, excessive hard disk and main hard disk, the first switch is connected between described common hard disc and excessive hard disk, second switch is connected between described excessive hard disk and main hard disk, described common hard disc, excessive hard disk is connected computer power supply by the first switch with second switch with main hard disk, described service isolator is also connected described computer power supply respectively with switching device shifter.
Preferably, described switching device shifter connects warning device, and when described switching device shifter is subject to illegally forbidding, described warning device gives the alarm.
Preferably, described warning device is hummer.
Preferably, described second switch is the single-pole switch with the synchronous interaction of described service isolator.
The utility model has the advantage of: a kind of computer network security shielding system provided by the utility model, its reasonable in design, accessing external network computer-chronograph main frame is with single hard disk work pattern, the data transmission between Intranet and outer net can be cut off in time when running into network risks, main frame is switched to three hard disk operational patterns simultaneously, ensure Intranet information security, set up with low cost, computing machine makes user's blocked operation in Inside and outside network by switching device shifter, switching device shifter connects warning device, the effect of warning illegal invasion can be played, stop the possibility of information leakage, there is good application value.
Accompanying drawing explanation
Fig. 1 is the theory diagram of a kind of computer network security shielding system provided by the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As everyone knows, when interior network operation, network environment is comparatively safe, at this time can consider that two hard disk works simultaneously, when accessing external network, network environment relative risk is larger, the mode of operation of independent hard disk can be adopted, when cut off outer net time again by secure data stored in main hard disk.
As shown in Figure 1, a kind of computer network security shielding system that the utility model provides, it is characterized in that: comprise main frame 1, described main frame 1 Connection Service isolator 2, described service isolator 2 connection switching apparatus 3, described switching device shifter 3 connects Intranet 4 and outer net 5, described switching device shifter 3 also connects warning device 12, when described switching device shifter 3 is subject to illegally forbidding, described warning device 12 gives the alarm, and described warning device 12 is hummer.
Common hard disc 6 parallel with one another, excessively hard disk 7 and main hard disk 8 is provided with in described main frame 1, the first switch 9 is connected between described common hard disc 6 and excessive hard disk 7, connect second switch 10 between described excessive hard disk 7 and main hard disk 8, described second switch 10 is the single-pole switch with the synchronous interaction of described service isolator 2.Described common hard disc 6, excessively hard disk 7 are connected computer power supply 11 by the first switch 9 with second switch 10 with main hard disk 8, and described service isolator 2 and switching device shifter 3 are also connected described computer power supply 11 respectively.
In use procedure, when serving isolator 2 and connecting outer net 5, the first switch 9 and second switch 10 disconnect, and main frame 1 is in the single hard disk mode of operation of common hard disc 6; When serve isolator 2 cut off outer net 5 connect time, second switch 10 first closes, data in described common hard disc 6 are first passed to excessive hard disk 7 by main frame 1 after tested, after safety, closed first switch 9 disconnects second switch 10 simultaneously again, and two hard disk modes that main frame 1 adds main hard disk 8 with excessive hard disk 7 in Intranet run.
