SYSTEM AND METHOD FOR TRAPPING NETWORK ATTACK ON EMBEDDED DEVICE IN SMART POWER GRID

摘要

Disclosed is a system for trapping a network attack on embedded devices in a smart power grid, comprising a trapping device and a security analyzing server; the trapping device comprises a network interface module, a security control module and an actual embedded device simulator; the network interface module is used to receive and transmit IP data packets; the security control module is used to identify, parse and distinguish the IP data packets, and is connected to a serial port communication module, an external memory and a switch module; the actual embedded device simulator transmits to the security analyzing server the network status and host status information; and the security analyzing server acquires a final security detection result via comprehensive multi-dimensional attribute measurement. The present invention can quickly and accurately conduct real-time dynamic security detection and evaluation on a known or unknown power system network attack without affecting the normal operation of embedded terminals, and effectively prevents an attacker from attacking the trapping device via the network interface module.
