摘要
为了评估电力光纤通信网络安全风险,文中介绍了一种电力光纤通信网络风险量化评价方法。对电力公司所管辖区域内的电力光纤通信网络的节点和链路进行风险量化评估,从数据状态和设备状态两方面引入节点/链路设备状态评估因子和数据状态评估因子。利用训练数据对基于WOA优化的LSTM模型进行训练,得到节点和链路下安全事件概率预测模型。对安全事件发生概率进行修正,根据节点或链路临近邻居节点和链路数量引入节点/链路临近参数以对设备安全事件的危害值进行修正,从而量化节点和链路的风险。最后通过实例验算了该量化评价方法。
In order to evaluate the security risks of power fiber optic communication networks,this article introduces a quantitative risk assessment method for power fiber optic communication networks.The risk assessment of nodes and links in the power fiber optic communication network within the jurisdiction of the power company is quantified.The node/link equipment status assessment factors and data status assessment factors from both data status and equipment status are introduced.Then,the LSTM model based on WOA optimization is trained by using training data to obtain a probability prediction model for security events under nodes and links,and modify the probability of security events occurring.By introducing node/link proximity parameters based on the number of neighboring nodes and links in a node or link,the hazard values of device security events are corrected to quantify the risks of nodes and links.Finally,the quantitative evaluation method is verified through an example.
