System and method for trapping network attack of embedded device of smart power grid

Abstract

The invention discloses a system for trapping network attack of an embedded device of a smart power grid. The system comprises a trapping device and a safety analysis server. The trapping device comprises a network interface module, a safety control module and an actual embedded device analog machine. The network interface module is used for receiving and transmitting an IP data package. The safety control module is used for identifying, analyzing and distinguishing the IP data package, and the safety control module is connected with a serial port communication module, an external memory and a switch module. The actual embedded device analog machine is used for sending network state information and mainframe state information to the safety analysis server. The safety analysis server is used for obtaining a final safety check result through multi-dimension attribute comprehensive measurement. By the adoption of the system, real-time dynamic security detection and evaluation can be quickly and accurately conducted on known or unknown electric power system network attack under the condition that normal operation of an embedded terminal is not affected, and meanwhile the trapping device can be effectively prevented from being attacked by attackers through the network interface module.

Description

technical field [0001] The invention relates to the field of network security defense, in particular to a system and method capable of trapping network attacks in a smart grid. Background technique [0002] At present, with the rise of the Internet of Things industry, in the smart grid, all kinds of sensors and control devices are embedded systems, which are widely used in the main links of power generation, power transmission, power transformation, power distribution and user power consumption. In addition to business measurement and transmission functions, the embedded system also plays a core business operation control function. For example, the multi-rate electric energy metering management unit at the user level, the transformer oil temperature sensor, voltage and current transmitter, relay protection device, fault recording, line protection, fault distance measuring device at the equipment layer, and digital recording in the control room , image monitoring of substati...
