Smart Grid based intelligent trapping system

Abstract

A Smart Grid based intelligent trapping system is disclosed. The Smart Grid based intelligent trapping system comprises a power grid load flow calculation center, an SCADA sub system and a Web display sub system, wherein the power grid load flow calculation center comprises a power grid model and an operation program and used for simulating operation of a real power grid; the SCADA sub system is used for simulating a smart meter and an actuator in the real power grid; and the Web display sub system is used for displaying states and control information of each node of the simulation power grid. According to the Smart Grid based intelligent trapping system, the smart grid and a network security technology are fused; the intelligent trapping system has the identical frameworks, parts and network interactive interfaces to the real power grid, so that the power grid state can be calculated in real time; correct response can be made when the power grid data is changed; when the power grid is invaded by an aggressor, same response as the real power grid can be made automatically to accord with expectation of the aggressor and to trick the aggressor to perform a next aggression step, so that the real aggression target and complete aggression tricks of the aggressor can be exposed; and finally, all behaviors of the aggressor can be captured by matching with an audit and capture sub system and a monitoring system.

Description

technical field [0001] The invention belongs to the technical field of smart grid security, in particular to an intelligent deception system based on SmartGrid. Background technique [0002] The smart grid (SmartGrid) system is an important industrial control system and the focus of the national "two modernizations" strategy, but there are many security holes in the smart grid, which may be invaded by attackers at any time. [0003] The number one threat to industrial control systems is malicious code attacks from the network. Industrial control systems use a large number of general-purpose protocols, general-purpose hardware and general-purpose software, and use the TCP / IP protocol to connect to the Internet, which provides sufficient convenience for the spread of malicious codes, making the security problems of industrial control systems increasingly serious. The reason why the "Stuxnet" (Stuxnet) incident caused heavy losses to Iran's nuclear power plant is that due to t...

Problems solved by technology

The traditional protection method is to replace the software and hardware in the power grid system to reduce the loopholes in the system, but this protection method has obvious disadvantages, namely hysteresis and vulnerability. Only when the power grid is attacked and losses are caused, the administrator Only then can we discover the existence of network attacks, so we can only passively replace the equipment, but cannot grasp the attacker's attack path, attack method, attack tool and exploited loopholes, cannot prescribe the right medicine, and cannot completely avoid the attacker's re-invasion, thus falling into the " In the vicious cycle of being attacked—replacing equipment—being attacked”
