Abstract

The utility model relates to a controller for computer network security. As for the problem of computer network security protection, an identical problem existing in the prior art is that both hard disks for storing confidential information and hard disks for storing unclassified information are powered on simultaneously, thereby conditions are provided for 'network hackers' to steal user information on line. The components of the controller include a double-pole-double-throw switch (2) connected with a computer internal power source (1), a confidential data storing hard disk (3) which is connected to one interface of the double-pole-double-throw switch, and an unclassified data storing hard disk (4) which is connected to the other interface of the double-pole-double-throw switch and is connected with a network switch (5), wherein the network switch is connected with a network card (6) and a computer network concentrator (7). The controller is used for protecting computer network security.

Description

Network security controller of computer

Technical field:

The utility model relates to a kind of network security controller of computer.

Background technology:

Along with rapid development of social economy, computing machine becomes the necessary article in people's work and the life, causes the computer network scale in continuous expansion, and therefore, the problem of computer information safe highlights.On the computer network security protection question, the technology that adopts at present is a lot, and the one, adopt and isolate card technique, isolate card with system software controls and select two different hard disks; The 2nd, computing machine adopts two kinds of different operating systems, controls two hard disks respectively; The 3rd, become two different workspaces to a hard disk partition, control with two kinds of different operating systems; The 4th, adopt duplex computer, a networking, one does not network; The 5th, connect netting twine when adopting online; Way of when not surfing the Net breaking off netting twine or the like; No matter all there is an identical problem in which type of technological hand way of above-mentioned employing, is exactly no matter to be the hard disk of storage security information; Still the hard disk of storing unclassified information all powers up work at the same time, and this steals user profile from network just for " network hacker " condition is provided.From technical standpoint, as long as computernetworking, hard disk is powering up work; " network hacker " just can change the subscriber computer working method from network; The technical measures of just not taked are not stolen user profile, and therefore, it is very necessary that a kind of network security controller is provided.

The utility model content:

The purpose of the utility model is that the problem that is directed against above-mentioned existence provides a kind of network security controller of computer, can guarantee being perfectly safe of computer user.

Above-mentioned purpose realizes through following technical scheme:

Network security controller of computer; Its composition comprises: the double-point double-throw switch that is connected with the computer-internal power supply; An interface of described double-point double-throw switch connects the hard disk of storage security data; Another interface of described double-point double-throw switch connects the hard disk of the unclassified data of storage, and the hard disk of the unclassified data of described storage connects the network switch, and the described network switch connects network interface card and computer network hub respectively.

Beneficial effect:

1. the utility model reasonable in design adopts double-point double-throw switch, and cost is low, is easy to promote.Simple connected mode has realized the optimal combination of circuit, can guarantee being perfectly safe of computer user, and no matter which type of technological means the hacker takes, and all can't steal user's data information.

Description of drawings:

Accompanying drawing 1 is the structural representation of the utility model.

Embodiment:

Embodiment 1:

Network security controller of computer; Its composition comprises: the double-point double-throw switch 2 that is connected with computer-internal power supply 1; An interface of described double-point double-throw switch connects the hard disk 3 of storage security data; Another interface of described double-point double-throw switch connects the hard disk 4 of the unclassified data of storage, and the hard disk of the unclassified data of described storage connects the network switch 5, and the described network switch connects network interface card 6 and computer network hub 7 respectively.

Its processing and fabricating of the network security controller of computer of the utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.

Claims

1. network security controller of computer; It is characterized in that: its composition comprises: the double-point double-throw switch that is connected with the computer-internal power supply; An interface of described double-point double-throw switch connects the hard disk of storage security data; Another interface of described double-point double-throw switch connects the hard disk of the unclassified data of storage, and the hard disk of the unclassified data of described storage connects the network switch, and the described network switch connects network interface card and computer network hub respectively.
