基于树状图的电力光纤通信网安全风险模型

Security risk modeling for dendriform chart-based electric power optical fiber communications networks

文章提出了基于树状图的电力光纤通信网安全风险的量化模型,详细分析了风险与其各个要素资产、威胁、脆弱性和安全措施之间的关系,并用公式具体解释了它们是如何构成风险的,结合电力通信网对各个因素的概念分类进行了阐述。通过建立树状图模型,得出各个因素之间的对应关系,对其合理赋值,通过计算得出了风险值,最后通过实例对模型进行了验证。

This article proposes a quantification model for the security risks of dendriform chart-based electric power optical fiber communications networks and analyzes in detail the relationship between the risks and its essential factors： assets, threat, vulnerability and the countermeasures. In addition, it specifically explains hy using a formula how these risks are constituted, elaborates on the concept classification of each factor in line with the electric power communications networks, obtains their corresponding relationship by establishing a dendriform chart model, reasonably evaluates them, thus obtaining the risk value through computations, and finally verifies the model through practical cases.
