Embodiment
[0060] see figure 1 , which shows the application scenario of the protection system involved in the first embodiment of the present invention.
[0061] Such as figure 1 As shown, the external terminal protection device is externally connected to the protected host through various interface connection lines, and each interface (UC1, UC2 of the USB port, CC1 of the COM port, EC0 of the network port) on the protected host that needs to be protected is passed through various Type of connection cable connected to its own internal interface, such as connecting the interfaces UC1 and UC2 of the protected host to the internal USB ports UA4 and UA3 of the external terminal protection device, and connecting the serial port CC1 to the internal serial port CA2 , the network port EC0 is connected to the internal network port EA2. And all kinds of external devices (U disk, optical drive, serial port connection equipment, etc.) are all connected to the external terminal protection device, ...

The invention discloses external terminal protection equipment based on space detection and a corresponding protection system. The external terminal protection equipment comprises an interface controlmodule used for being connected with a protected host and an external device; an internal memory which is used for storing data exchanged between the interfaces; a space detection module which is used for detecting whether the protection equipment is displaced or not and sending a data erasing instruction to the internal memory when the protection equipment is displaced; a system control module which is used for carrying out security authentication on external equipment accessed to an external interface, is electrically connected with the space detection module and is used for starting or closing a position detection function of the space detection module; and a power supply module for supplying power. According to the invention, the purpose of performing safety protection on the protected host can be achieved without installing safety protection software on the protected host, and the potential safety hazard of data leakage of the internal memory after the protection equipment is physically damaged can be prevented.
Description
technical field [0001] The invention belongs to the technical field of computer security, and in particular relates to an external terminal protection device and a protection system based on space detection. Background technique [0002] In recent years, the rapid development of computer and information technology has greatly promoted the popularization of the network. When people enjoy the convenience brought by this computer and information technology, it is also the data in the computer used by people in production / life. Security has brought new threats, such as common unauthorized access, posing as a legitimate user, destroying data integrity, interfering with the normal operation of the system, using the network to spread viruses, and man-in-the-middle eavesdropping and so on. [0003] There are many technical means to solve intranet security problems, such as installing and using network security products such as firewalls, anti-viruses, and intrusion detection systems...
