Embodiment 1

[0017] Embodiment 1, in figure 1 A physical disconnection device includes a network card chip U1, a PCIE data buffer U2, a network interface, a USB interface, an NPN phototransistor Q1, a pull-down resistor R1, a light emitting diode D1, and a current limiting resistor R2.

[0018] Light-emitting diode D1, current-limiting resistor R2, phototransistor Q1, and pull-down resistor R1 together form a photogate. Phototransistor Q1 is located on the left side of the USB interface, and light-emitting diode D1 is located on the right side of the USB interface. The light emitted by the light-emitting diode D1 passes through the USB interface. The interior shines on the phototransistor Q1.

[0019] The output pin of the photogate is connected to the enable pin of the PCIE data buffer U2.

[0020] When the USB device is plugged in, the light emitted by the LED D1 is blocked, the phototransistor Q1 cannot receive the light of the LED D1, and enters the cut-off state, the level of the out...

Abstract

The invention discloses a computer. A correlation type photogate is used for detecting whether a USB is plugged, and a light path penetrates through the inside of a USB interface; a PCIE buffer is used for controlling a data channel between a network card chip and a PCIE port, thus realizing network outage of the network card chip in a physical layer; an electronic circuit associates the use state of the USB interface with the working state of the PCIE buffer; when the USB interface is detected to be plugged, the PCIE buffer does not work, the data channel between a network card and the PCIE port stops data transmission, and a network interface is cut off; and when the USB interface is not plugged, the PCIE buffer works, the data channel between the network card and the PCIE port normally transmits data, and connection of the network interface is recovered. The invention further discloses an information security network which is provided with the security computer. The invention further discloses a municipal unit information security network which has the information security network. The computer can detect plugging of USB equipment in real time and realize network outage on the physical layer, thus avoiding the attack of viruses in the USB equipment to the network when antivirus software fails.

Description

technical field [0001] The invention belongs to the field of electronics, and in particular relates to a computer, an information security network, and a municipal unit information security network. Background technique [0002] With the emergence and development of USB storage devices, people's security requirements for paperless office and large-capacity storage devices are increasing day by day. [0003] While USB storage devices bring us convenience, they also provide opportunities for illegal access to computer data, copying and leaking or sensitive data. Security vendors such as anti-virus software mainly protect against viruses for reading and writing data on USB storage devices, but they cannot prevent the occurrence of file theft. If there is a technology that can cut off the network when the USB storage device is inserted, it can prevent important files in the USB storage device from being stolen. [0004] Anti-virus software is used in the LAN to control the saf...
