Vulnerability scoring for security configuration settings

The best-known vulnerability scoring standard, the Common Vulnerability Scoring System (CVSS), is designed to quantify the severity of security-related software flaw vulnerabilities. This paper describes our efforts to determine if CVSS could be adapted for use with a different type of vulnerability: security configuration settings. We have identified significant differences in scoring configuration settings and software flaws and have proposed methods for accommodating those differences. We also generated scores for 187 configuration settings to evaluate the new specification.
