Abstract

The utility model relates to a computer network safety coefficient, include: first, second processor module, primary hard drive and reserve hard disk, and primary hard drive and reserve hard disk carry out data communication through two -way data pin with the computer respectively, and still include: a network data monitoring module for monitoring whether outer net IP visits local data for carry out the hard disk data monitoring module that hard disk reading and writing switching was monitored to primary hard drive or reserve hard disk, the first processor module is suitable for the corresponding outer net IP who detects the hard disk data monitoring module to send the monitoring module to network data to the reading and writing action of primary hard drive or reserve hard disk, the network data monitoring module regards as malicious IP address to save this outer net IP to shield this IP address.

Description

A kind of Computer Network Security System

Technical field

This utility model is related to technical field of the computer network, and in particular to a kind of Computer Network Security System.

Background technology

With the development of computer network, also come more to be taken seriously with regard to the safety issue of computerized information, the network information Steal, information attack, virus disseminating etc. all exist all the time and occur.On computer network security protection question, mesh The technology of front employing is a lot, and for example with isolation technology, the data channel of control two pieces of hard disks of switching, to reach security protection Purpose, the method exist problem be：If the processor module for being responsible for data channel switching is not responded, can cause to isolate Computer Primary Hard Drive, causes data illegally to be read or write.

The content of the invention

The purpose of this utility model is to provide a kind of Computer Network Security System, when malicious attack is tackled, IP is entered Row record, and shielded, prevent the IP and aggressive behavior has occurred again.

In order to solve above-mentioned technical problem, this utility model provides a kind of Computer Network Security System, including：The First, second processing device module, Primary Hard Drive and alternate hard, and Primary Hard Drive passes through bi-directional data plug and meter respectively with alternate hard Calculation machine carries out data communication, and also includes：Whether the Network Data Control module of local data is accessed for monitoring outer net IP, For carrying out the hard disc data monitoring module of disk read-write switching monitoring to Primary Hard Drive or alternate hard；The first processor mould The corresponding outer net IP that block is suitable to detect hard disc data monitoring module is sent for the read-write behavior of Primary Hard Drive or alternate hard To Network Data Control module, outer net IP is stored by the Network Data Control module as malicious IP addresses, with right The IP address is shielded.

Further, the hard disc data monitoring module is also connected with second processing device module, the first processor module The data channel of Primary Hard Drive and alternate hard is switched by switching value output module；Operation is written and read to Primary Hard Drive in outer net IP When, if data channel is not switched to alternate hard by first processor module, the second processing device module passes through electronic cutting The power supply of disconnected two hard disks deeply concerned.

Further, the second processing device module is also connected with clock chip, so that second processing device module is in setting Between reach after, close electrical switch.

The beneficial effects of the utility model are that Computer Network Security System of the present utility model can be processed by first Device module accesses switching between Primary Hard Drive and alternate hard, and for the IP with malicious attack property is recorded and shielded Cover, it is to avoid above-mentioned IP repeat attacks again, if second processing device module judges that first processor module cannot realize data channel Switching, then actively disconnect the power supply of first processor module, make Primary Hard Drive completely isolated.

Description of the drawings

With reference to the accompanying drawings and examples this utility model is further illustrated.

Fig. 1 is the theory diagram of Computer Network Security System of the present utility model.

Specific embodiment

This utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram, Basic structure of the present utility model is only illustrated in a schematic way, therefore which only shows the composition relevant with this utility model.

As shown in figure 1, a kind of Computer Network Security System of the present utility model, including：First, second processor die Block, Primary Hard Drive and alternate hard, and Primary Hard Drive and alternate hard to carry out data by bi-directional data plug and computer respectively logical News, and also include：Whether access the Network Data Control module of local data for monitoring outer net IP, for Primary Hard Drive or Alternate hard carries out the hard disc data monitoring module of disk read-write switching monitoring；The first processor module is suitable to hard disk number Send to Network Data Control for the read-write behavior of Primary Hard Drive or alternate hard according to the corresponding outer net IP that monitoring module is detected Outer net IP is stored by module, the Network Data Control module as malicious IP addresses, to shield to the IP address Cover.

Specifically, the Network Data Control module is suitable to include sub-module stored, to store to malicious IP addresses.

Further, the hard disc data monitoring module is also connected with second processing device module, the first processor module The data channel of Primary Hard Drive and alternate hard is switched by switching value output module；Operation is written and read to Primary Hard Drive in outer net IP When, if data channel is not switched to alternate hard by first processor module, the second processing device module passes through electronic cutting The power supply of disconnected two hard disks deeply concerned, to ensure Primary Hard Drive data safety.Can also be by second processing device module at first Reason device module sends handshake, if now first processor module is not responded, by disconnecting electrical switch, cuts off two hard disks Power supply.

The second processing device module is also connected with clock chip, so that second processing device module is reached in setting time Afterwards, close electrical switch.

Wherein, first, second processor module is suitable for use with STC series monolithics or embedded chip.

The second processing device module is also associated with alarm module, when the control electrical switch cut-out of second processing device module is supplied After power supply, warning is sent to manager by alarm module.

With it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, by above-mentioned description, related work people Member can carry out various change and modification completely in the range of without departing from this utility model technological thought.This reality The content being not limited to new technical scope in description, it is necessary to determine its technology according to right Property scope.
