Abstract
The present invention discloses a hardware control logic based data forwarding control method and a corresponding data forwarding control system. The method includes: externally connecting a terminal protection device to a protected host, and taking over all the data interfaces of the protected host; and controlling by a hardware control logic in the terminal protection device the connection and/or disconnection of a physical circuit corresponding to data forwarding when an external device interacts data with the protected host via the terminal protection device, so as to control the data interaction between the external device and the protected host. The present invention realizes the functions of performing control and security protection on various types of data without installing data monitoring and security protection software on the protected host, and achieves the effects of isolating the physical circuit via the hardware control logic and better controlling data forwarding security, thereby comprehensively eliminating the potential security hazards such as Trojan virus implantation and malicious code injection that may be generated by the interfaces.
