Description

FIELD OF TECHNOLOGY

The invention relates to the field of switching computer networks, protecting networks and computers from unauthorized access and can be used in computer networks to control computer access to various networks in the form of terminating access to a computer from one or more networks and / or restricting access from one network to another .

BACKGROUND

There are many different hardware and software systems for restricting access and / or disconnecting a computer from one or more computer networks [1, 2, 3, 4, 5]. A prototype can be considered [5].

SUMMARY OF THE INVENTION

The essence of the invention lies in the fact that the computer is connected to one or more computer networks through an external device, the software of which, including the user interface, is installed on the computer. By means of the user interface, computer networks are switched with a computer in the following variants:

- complete cessation of access by a computer user to all computer networks connected to an external device;

- selective access by a computer user to one or more computer networks connected to an external device;

- full open access by a computer user to all computer networks connected to an external device.

It is also possible, using the user interface, to carry out switching between themselves computer networks connected to an external device, and with the possibility of push-button control of the operating mode without using software.

BRIEF DESCRIPTION OF THE DRAWING

In FIG. 1 shows a block diagram of the functioning of a hardware-software complex. Through connector 1, the hardware-software complex is connected to the connectors of the network card of computer 2 for interaction with the interface of the computer's network card. Implementation of connector 1 is possible in the form of an RJ-45 connector. Connector 3 is used to control and supply voltage to the power controller 4. Implementation of connector 3 is possible in the form of a USB connector. The power controller 4 contains a power indicator 5, made in the form of an LED that lights up when there is a supply voltage. The power controller supplies the operating voltage to the microcontroller 6, which provides control of the entire software and hardware complex. There may be a button switch 7 for controlling the operating mode of the microcontroller. For example, for switching computer network connections inside the hardware and software complex without the participation of the hardware and software of computer 2. Microcontroller 6 supplies a control signal to switch 8, which is connected to computer networks 9, 10 through connectors 11, 12. The switch, depending on the control signal provides various types of switching between a computer and networks and / or between networks. For example, connecting one or two computer networks to a computer or disconnecting both, as well as switching, that is, connecting or disconnecting networks between themselves. Perhaps the presence of indicators 13, 14 to indicate the connection to the computer of one or both networks.

DETAILED DESCRIPTION OF THE INVENTION

Implementation of the proposed hardware-software complex is possible using any types of microprocessor technology and software known from the existing level of technology. The hardware-software complex itself is housed in a housing with indicators brought out and a push-button switch. To connect all components of the hardware-software complex with each other, as well as with a computer and networks, any kind of connections and connectors can be used.
