Which published standard provides an open framework for communicating the characteristics and impacts of IT vulnerabilities?

• A. Buffer Overflows
• B. Common Weakness Enumeration (CWE)
• C. Common Vulnerability Scoring System (CVSS)
• D. National Vulnerability Database (NVD)

Answer: (C)

CVSS, the Common Vulnerability Scoring System, provides an open framework for describing and communicating how a vulnerability can affect a system and how severe it is. It breaks down vulnerability characteristics into base metrics—such as attack vector, attack complexity, privileges required, user interaction, scope, and the impacts on confidentiality, integrity, and availability—and can include temporal and environmental metrics to adjust the score for changing conditions. This structure yields a numeric score plus a qualitative severity rating, enabling clear, consistent risk communication across different teams and vendors. The open nature of CVSS allows widely shared and comparable assessments, which is why it’s used as the standard framework for vulnerability communication. The other options aren’t frameworks for communicating vulnerability characteristics and impacts: buffer overflows are a type of vulnerability, CWE is a taxonomy of weakness types, and NVD is a vulnerability database that uses CVSS scores rather than providing the framework itself.
