Query: A Non-Intrusive and Context-Based Vulnerability Scoring Framework for
  Cloud Services   Understanding the severity of vulnerabilities within cloud services is
particularly important for today service administrators.Although many systems,
e.g., CVSS, have been built to evaluate and score the severity of
vulnerabilities for administrators, the scoring schemes employed by these
systems fail to take into account the contextual information of specific
services having these vulnerabilities, such as what roles they play in a
particular service. Such a deficiency makes resulting scores unhelpful. This
paper presents a practical framework, NCVS, that offers automatic and
contextual scoring mechanism to evaluate the severity of vulnerabilities for a
particular service. Specifically, for a given service S, NCVS first
automatically collects S contextual information including topology,
configurations, vulnerabilities and their dependencies. Then, NCVS uses the
collected information to build a contextual dependency graph, named CDG, to
model S context. Finally, NCVS scores and ranks all the vulnerabilities in S by
analyzing S context, such as what roles the vulnerabilities play in S, and how
critical they affect the functionality of S. NCVS is novel and useful, because
1) context-based vulnerability scoring results are highly relevant and
meaningful for administrators to understand each vulnerability importance
specific to the target service; and 2) the workflow of NCVS does not need
instrumentation or modifications to any source code. Our experimental results
demonstrate that NCVS can obtain more relevant vulnerability scoring results
than comparable system, such as CVSS.
