The invention provides an intrusion prevention system of a DC motor control system. The intrusion prevention system can realize the safe collection of DC motor operation data and the intrusion prevention of the DC motor control system. The device comprises: a collection unit, configured to collect motor operation data in the DC motor control system, and send the motor operation data to an intrusion detection unit; the intrusion detection unit, configured to encrypt the received motor operation data, and send the encrypted motor operation data to a monitoring unit, as well as perform intrusiondetection on received network communication data in the DC motor control system, and if there is an intrusion behavior, send alarm information; and the monitoring unit, configured to receive the encrypted motor operation data and decrypt the same, as well as send a control instruction to the DC motor control system. The invention relates to the field of industrial control network security.
Description
technical field [0001] The invention relates to the field of industrial control network security, in particular to an intrusion prevention system of a DC motor control system. Background technique [0002] In recent years, intrusion attacks against industrial control network equipment have become more frequent, especially the DC motor control system under the industrial control network environment. The industrial control system involves the application layer, host layer physical layer, network layer and other cyber-physical system security issues. In the industrial control system, most industrial control software is installed on the general-purpose operating system. Based on the stability requirements of the system, the operating system will not be patched and optimized after the system is running. In addition, the industrial control network is usually a dedicated internal network. Connected to the Internet, ability to update virus database and anti-virus software to detect...
