摘　　要：为了解决SCADA系统信息安全的问题,本文提出了一种基于因素神经网络的主动防御方法。将SCADA系统信息安全的影响因素映射到因素空间坐标中,然后利用知识因素的因素神经元表示方法,通过云模型推理机实现了语言值表示的模糊概念到定量数据的转换,并通过云模型多规则多条件发生器进行规则推理,最后根据得到的期望值又可以转换为定性语言值,这样就实现了对未知恶意程序行为操作可能性的预测。本文着重于利用基于云模型的多条件多规则发生器实现推理,通过MATLAB进行算法设计和仿真,为油气SCADA系统信息安全防御的解决方法提供了一种思路。Over recent years, with the amount of incidents involving industrial control information systems, the safe- ty of these system has been given increased importance across the Globe, and several technical measures have been implented to improve this. This paper proposed an active defense method based on a factor neural network in refer- ence to SCADA information security. The different aspects of SCADA information security were mapped to factor co- ordinates, and the factor neuron method for knowledge factors was then used to transform this from a fuzzy concept （represented by language ） to quantitative data through a cloud inference engine. Inference was then conducted through generated multi conditions and multi rules based on a cloud model, so that it could then be transformed into a qualitative language （e.g. ‘more likely＇ based on Ex） to be able to forecast the consequences of unknown mali- cious programs. This paper focus on using a generator with multiple conditions and rules based on a cloud model to achieve inference, thus providing an idea of the oil and gas SCADA information security＇ s defense response using algorithmic design and MATLAB-based simulations.
