CAS-004 Security Operations Practice Question
A vulnerability management team is prioritizing patches for a large enterprise. They have identified a critical vulnerability in a widely used software with a CVSS base score of 9.8. However, the exploit requires local access and authentication. Which CVSS metric should the team use to adjust the score to reflect the actual risk in their environment?

Correct answer & explanation
✓
Environmental score
The question asks for a metric to adjust the CVSS base score to reflect actual risk in the organization's specific environment. The Environmental score is designed for this purpose, allowing customization based on factors such as security controls, asset criticality, and compensating measures. In contrast, the Temporal score adjusts for factors that change over time (e.g., exploit maturity), but it does not account for organization-specific context. Therefore, the Environmental score is the correct metric to use.
