Abstract

The invention provides a security defense method and device, relates to the technical field of Internet of Things, and aims to timely and effectively realize security defense of Internet of Things equipment and improve the security of the Internet of Things equipment. The method comprises the following steps: acquiring the position (i.e., a first position) of Internet of Things equipment at the current moment, the position (i.e., a second position) of the Internet of Things equipment at the previous preset moment of the current moment, the information transceiving frequency at the current moment and the information transmission rate at the current moment; determining a position change rate of movement from the second position to the first position; according to at least one of the positionchange rate, the information transceiving frequency and the information transmission rate, determining whether the operation state of the Internet of Things equipment is abnormal or not; and when itis determined that the operation state of the Internet of Things equipment is abnormal, cutting off the network connection between the Internet of Things equipment and the Internet of Things system.

Description

technical field [0001] The present application relates to the technical field of the Internet of Things, and in particular to a security defense method and device. Background technique [0002] The Internet of Things is a network that carries various information such as the Internet and traditional telecommunication networks, and enables all ordinary objects that can perform independent functions to realize interconnection. Usually, users can realize remote control and centralized management of automobiles, household equipment and other equipment through the Internet of Things, and can also collect and analyze data from IoT devices to achieve big data analysis for disaster prediction, crime prevention, and epidemic control Wait. [0003] At present, IoT devices are usually connected to the Internet by default, and their codes are generally open source. In this way, any user can obtain the code of the IoT device, which reduces the security of the IoT device. However, most ...
