Which vulnerability metric scores from 0 to 10 to help assess vulnerabilities across an organization?

The correct choice is the Common Vulnerability Scoring System (CVSS), which provides a standardized framework for rating the severity of security vulnerabilities in software. The CVSS scores range from 0 to 10, where lower scores indicate less severe vulnerabilities and higher scores indicate critical security issues that require immediate attention.

The CVSS metric is crucial for organizations as it helps in prioritizing vulnerabilities based on their potential impact and exploitability within their specific environment. Using this scoring system allows security teams to communicate the seriousness of vulnerabilities efficiently and establish a risk-based approach to remediation efforts.

Other options relate to different aspects of cybersecurity. CVSS2, for example, refers specifically to an earlier version of the scoring system, which may not provide the comprehensive insights that the updated CVSS offers. OWASP (Open Web Application Security Project) focuses on improving the security of software, offering guidelines and resources rather than a scoring system. CVE (Common Vulnerabilities and Exposures) is a list of publicly known cybersecurity vulnerabilities but does not provide a scoring mechanism; it catalogues vulnerabilities identified and indexed for reference.

Thus, CVSS serves as a key tool for effectively measuring and responding to vulnerability risks in an organization.
