Embodiment Construction
[0041] In order to solve the technical problems raised in the background technology, the inventors of the present application thought of setting up a hardware firewall between the terminal and the IoT device, the hardware firewall stores filtering rules for verifying control commands; After the control command is issued, the control command is verified according to the preset filtering rules. Only after the control command is verified, the hardware firewall sends the control command to the IoT device, so that the IoT device executes the control command. In this way, dangerous accidents caused by the tampering of the content of the control instruction are avoided, the protection of the Internet of Things equipment is realized, and the security of the operation of the Internet of Things equipment is improved.
[0042] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further ...

The invention discloses an Internet of Things equipment protection method and device. The method comprises the steps that a control instruction sent by a terminal is received; the control instructionis verified according to a preset filtering rule; and if the control instruction passes verification, the control instruction is sent to Internet of Things equipment to enable the Internet of Things equipment to execute the control instruction. According to the Internet of Things equipment protection method and device, it can be seen that a hardware firewall is arranged between the terminal and the Internet of Things equipment, and the filtering rule for verifying the control instruction is stored in the hardware firewall; and the hardware firewall verifies the control instruction according tothe preset filtering rule after receiving the control instruction sent by the terminal, only after the control instruction passes verification, the hardware firewall can send the control instructionto the Internet of Things equipment to enable the Internet of Things equipment to execute the control instruction, therefore, dangerous accidents caused by the fact that content of the control instruction is tampered are avoided, protection on the Internet of Things equipment is achieved, and the operation security of the Internet of Things equipment is improved.
Description
technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a method and device for protecting Internet of Things equipment. Background technique [0002] With the advancement of network technology, various devices in the physical world can be connected to the Internet to form the Internet of Things. In the Internet of Things, the control of the Internet of Things devices can be realized by sending control commands to the Internet of Things devices through terminals such as mobile phones. [0003] In the entire communication link between the terminal and the IoT device, the content of the control command may be tampered with, and it may also happen that an attacker uses an unauthenticated terminal to maliciously send a control command to the IoT device. If the content of the control command cannot be safely restricted or the terminal sending the control command cannot be authenticated, dangerous accidents may occur. For e...
