Security protection methods, devices and system

Abstract

The invention discloses security protection methods, devices and system. A method comprises the steps that a security server receives real-time traffic information of Internet of things equipment sentby a security gateway, and determines a target feature value of a preset traffic feature corresponding to a current detection period of the Internet of things equipment according to traffic information of the Internet of things equipment at each moment within the current detection period; judging whether a difference value between the target feature value and a predicted feature value of a presettraffic feature corresponding to the current detection period is smaller than a deviation threshold or not, wherein the predicted feature value is determined according to each history feature value of the preset traffic feature corresponding to the set number of history detection periods before the current detection period, and a preset prediction algorithm; and if the difference value is not smaller than the deviation threshold, a blocking instruction for blocking traffic transmission of the Internet of things equipment is sent to the security gateway, so the security gateway blocks the traffic transmission of the Internet of things equipment. A provided security protection scheme is used for ensuring security of the Internet of things equipment.

Description

technical field [0001] The present invention relates to the technical field of network security, in particular to a security protection method, device and system. Background technique [0002] The Internet of Things (IOT) is the third wave of information development after the development of computers and the Internet. The Internet of Things refers to a network that connects items with various networks for information exchange and communication in accordance with agreed protocols to achieve intelligent identification, positioning, tracking, monitoring and management. The Internet of Things will realize the extensive "networking" of things and things, people and things, and the network and people's daily life will be closer in the era of the Internet of Things. With the development of Internet of Things technology, the application of Internet of Things devices in industrial manufacturing, smart home and other fields has increased, which has brought great convenience to people...

Problems solved by technology

[0003] However, as the public gradually shifts their attention to the Internet of Things, the security of IoT devices is also coveted by malicious attackers. Due to the wide variety of IoT devices and widespread exposure, IoT devices are extremely fragile and easy to be attacked Vulnerabilities are discovered and exploited by the attackers, resulting in the illegal manipulation of IoT devices, the decline of user experience, and even the modification of some important data of IoT devices, causing IoT device failures and serious security incidents. Therefore, a security protection solution is urgently needed. To protect the security of IoT devices
