Query: A Novel Model for Vulnerability Analysis through Enhanced Directed
  Graphs and Quantitative Metrics   Industrial components are of high importance because they control critical
infrastructures that form the lifeline of modern societies. However, the rapid
evolution of industrial components, together with the new paradigm of Industry
4.0, and the new connectivity features that will be introduced by the 5G
technology, all increase the likelihood of security incidents. These incidents
are caused by the vulnerabilities present in these devices. In addition,
although international standards define tasks to assess vulnerabilities, they
do not specify any particular method. Having a secure design is important, but
is also complex, costly, and an extra factor to manage during the lifespan of
the device. This paper presents a model to analyze the known vulnerabilities of
industrial components over time. The proposed model is based on two main
elements: a directed graph representation of the internal structure of the
component, and a set of quantitative metrics that are based on international
security standards; such as, the Common Vulnerability Scoring System (CVSS).
This model is applied throughout the entire lifespan of a device to track
vulnerabilities, identify new requirements, root causes, and test cases. The
proposed model also helps to prioritize patching activities. To test its
potential, the proposed model is applied to the OpenPLC project. The results
show that most of the root causes of these vulnerabilities are related to
memory buffer operations and are concentrated in the \textit{libssl} library.
Consequently, new requirements and test cases were generated from the obtained
data.
