Description
Technical field
A kind of computer realm, and in particular to information safety computer circuit.
Technical background
Secret unit requires all high to information privacy and Information Security, and computer virus, wooden horse are present information
The saboteur of safety, movable storage medium is indispensable office appliance, and movable storage medium is typically virus, wooden horse
The major reason of secret unit is brought into, if whether containing viral, wooden horse in a special killing movable storage medium
Computer, carrying out virus, wooden horse killing to movable storage medium every time can prevent that movable storage medium from bringing virus into；
Computer antivirus is killed virus by antivirus software, and computer network security attacking and defending is the trial of strength of an information, usual black and white
Both sides are in the technology of oneself of constantly upgrading, and some virus can even kill antivirus software, make antivirus software ineffective
(such as famous Panda burning incense virus once made the antivirus software of the companies such as Rising, Kingsoft fail), so antivirus software is continuous
Extremely important, the antivirus software on computer in existing internal security network of upgrading, will generally pass through internal security network
It is connected to master server to be upgraded, if the whether virulent special-purpose computer of killing movable storage medium, inserts removable
If there is network while dynamic storage medium, then existence information passage between movable storage medium and master server, viral
It may be propagated after destruction antivirus software makes antivirus software fail in netting, it is also possible to preempt the leading biography of antivirus software action
Broadcast, if this is connected on internal network during antivirus special-purpose computer antivirus, then will be provided to virus attack master server
Possible passage, so the killing special purpose computer of movable storage medium is, it is necessary to ensure networking upgrading to update disease as soon as possible
Malicious storehouse or antivirus software main program, it is also desirable to ensure that movable storage medium insertion is dedicated computing chance suspension, antivirus is completed,
Observation analysis movable storage medium it is normal it is virus-free after allow movable storage medium internally to use again, be conducive to in-house network
Network safety, reduces the possibility that virus is brought in.USB flash disk suspension can prevent that wooden horse, virus from being stolen in USB flash disk by PC
Information, prevents that important information from being stolen by wooden horse, virus, insertion USB flash disk is that automatic suspension can prevent that file from being stolen simultaneously by wooden horse
Sent immediately by network.
Because virus, wooden horse are all the software that is run under system environments, if suspension mode is using in computer system
The software of operation is carried out, then the software can suffer from the viral, attack of wooden horse and fail, therefore take physics suspension, cut completely
The disconnected mode for hindering passage is only really reliably.
The content of the invention
1st, a kind of information security implementation method, for the calculating with network interface, the hardware of movable storage medium interface
Machine and design, it is characterised in that：Network is all off when at least one movable storage medium interface is used on computer, real
Existing mode is implemented by physical method, computer meeting before message reference Path Setup between computer and movable storage medium
Network interface is disconnected, prevents that the movable storage medium interface on computer is used simultaneously with network interface；For protecting letter
Cease safeguard protection purposes.
2nd, a kind of computer, with any one foregoing technical scheme.
3rd, a kind of secure network, with any one foregoing technical scheme.
Technique effect.
, can be with the security of Strengthens network, energy the beneficial effects of the present invention are movable storage medium insertion with regard to suspension
Enough prevent that vital document from being stolen by wooden horse.
