What type of data does the Common Vulnerability Scoring System (CVSS) utilize for vulnerability assessment?

The Common Vulnerability Scoring System (CVSS) leverages vulnerability metrics to assess the severity of security vulnerabilities in software and systems. These metrics provide a standardized way to quantify the characteristics and impacts of vulnerabilities, allowing organizations to prioritize their response based on the risk posed.

CVSS includes multiple metrics divided into three groups: base metrics (which assess the intrinsic qualities of a vulnerability), temporal metrics (which evaluate the current state of exploitability), and environmental metrics (which consider the specific environment in which the vulnerability exists). This structured approach allows security professionals to effectively communicate the risk associated with vulnerabilities and to make informed decisions about remediation and mitigation strategies.

The other options do not fit within the framework of CVSS. Application performance metrics refer to the performance and health of software applications rather than security vulnerability assessment. Security compliance checklists focus on meeting specific regulatory or organizational standards rather than evaluating the technical aspects of vulnerabilities. Threat intelligence data is valuable for understanding the current threat landscape but does not serve as a primary input for scoring vulnerabilities like CVSS metrics do.
