概要

CVSS (Common Vulnerability Scoring System) is a standardized framework for assessing vulnerability severity and impact. Essential for vulnerability management, risk prioritization, and security reporting across organizations.

CVSS Risk Scoringとは

CVSS is a standardized framework published by FIRST (Forum of Incident Response and Security Teams) for rating the severity of security vulnerabilities. It provides a numerical score (0–10) based on technical characteristics, enabling consistent vulnerability comparison and prioritization. Job relevance: Security analysts, vulnerability managers, risk officers, and security architects need CVSS expertise for vulnerability management and compliance (PCI DSS, etc.).

❓ よくある質問

What's the difference between CVSS 3.1 and 4.0?

CVSS 4.0 improves vector consistency and accuracy; 3.1 still widely used during transition.

What's a good CVSS score?

Depends on context; generally <4.0 Low, 4–6.9 Medium, 7–8.9 High, 9–10 Critical.

Who calculates CVSS scores?

NVD, vendors, and security researchers; organizations can compute scores themselves.

How does CVSS relate to exploitability?

CVSS doesn't measure actual exploit availability; use threat intelligence for that.

Should I prioritize by CVSS alone?

No, consider context (affected systems, exploitability, business impact).

Can environmental factors change CVSS?

CVSS 3.1+ includes Environmental Score for context; base score remains constant.
