Abstract

The invention discloses a closed-source electric power industrial control system behavior pattern classification method and device. The classification method comprises the following steps: acquiring a normal data packet of a target electric power industrial control system; performing feature extraction processing on the normal data packet, and constructing a normal behavior pattern feature library; acquiring a to-be-tested data packet; according to the normal behavior pattern feature library, determining the type of the to-be-tested data packet, and the type comprising a normal behavior pattern and an abnormal behavior pattern. According to the method and the device, the actual communication behavior of the industrial control system can be learned off line in combination with the constructed normal behavior mode feature library, so that the behavior mode of the industrial control system is summarized in an actual attack scene lacking a power supply, network attack detection is assisted, and the reliability and the safety of the power industrial control system are maintained.

Description

technical field [0001] The invention relates to the field of information security of electric power industrial control systems, in particular to a method and device for classifying behavior patterns of closed-source electric power industrial control systems. Background technique [0002] Industrial control systems are the core components of industrial infrastructure such as electric power, metallurgy, transportation, and energy, and are also an important foundation for national economy, social operation, and national security. In recent years, with the development of science and technology, the degree of informatization has also been improved. At the same time, various new attack technologies and methods against industrial control systems have emerged in an endless stream. Stuxnet virus, Flame virus, BlackEnergy, etc. have clear targeted attack characteristics. The means of attack make the power industrial control system face more complex internal and external threats, and h...
