Command security defense method and command security defense system

Abstract

The invention discloses a command security defense method and command security defense system, comprising: step S1, acquiring response action information after a target object device executes the received target command; step S2, judging whether the response action information satisfies the target command The corresponding security response rule or the threat detection rule corresponding to the target instruction; if it is determined that the response action information satisfies the security response rule, step S3 is performed; if it is determined that the response action information satisfies the threat detection rule, step S4 is performed; The target object device sends reminder information to remind the target object device that the received target instruction and its own response are safe; step S4, send reminder information to the target object device, so that the target object device can respond to the target instruction and its own action. isolate. The technical scheme of the present invention can provide a security defense mechanism for instructions for the Internet of Things device, and effectively guarantee the security of the Internet of Things device in the process of executing the instructions.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to an instruction security defense method and an instruction security defense system. Background technique [0002] The Internet of Things is divided into three layers: the application layer, the perception layer, and the transport layer. Each layer of the Internet of Things will face different security risks. At the application layer, most services are deployed on the cloud, and business applications may be hijacked, resulting in security risks in remote commands sent from the business system to terminals at the perception layer; terminal devices at the perception layer, in addition to data collection and transmission, also need to identify and In response to remote instructions sent by the business system, if the instructions are wrong, it may cause irreparable losses. Therefore, to prevent hijacking, illegal takeover and control of business applications, it is nec...
