软件最大安全漏洞的度量

Measurements of the Most Significant Software Security Weaknesses

Carlos Cardoso Galhardo, Peter Mell, Irena Bojanova, Assane Gueye

摘要:

在这项工作中,我们提供了一个指标来计算最重要的软件安全漏洞,这些漏洞由相关漏洞的频率,可利用性和影响的聚合指标定义。常见弱点枚举(CWE)是一个众所周知的软件安全弱点列表。CWE社区发布了这样一个汇总指标来计算“最危险的软件错误”。然而,我们发现,公布的公式高度偏见的频率,几乎忽略了利用和影响,在产生不同规模的顶级名单。这是由于分量度量值的分布的差异。为了减轻这种情况,我们使用双对数函数线性化频率分布。然后,我们提出了各种其他改进措施,提供了2019年最重要的CWE列表,对已识别的软件安全漏洞进行了分析,并将其与之前发布的列表进行了比较。

英文摘要:

In this work, we provide a metric to calculate the most significant software security weaknesses as defined by an aggregate metric of the frequency, exploitability, and impact of related vulnerabilities. The Common Weakness Enumeration (CWE) is a well-known and used list of software security weaknesses. The CWE community publishes such an aggregate metric to calculate the `Most Dangerous Software Errors'. However, we find that the published equation highly biases frequency and almost ignores exploitability and impact in generating top lists of varying sizes. This is due to the differences in the distributions of the component metric values. To mitigate this, we linearize the frequency distribution using a double log function. We then propose a variety of other improvements, provide top lists of the most significant CWEs for 2019, provide an analysis of the identified software security weaknesses, and compare them against previously published top lists.
