CompTIA Exam PT0-003 Topic 3 Question 25 Discussion

The Common Vulnerability Scoring System (CVSS) provides a standardized way to evaluate the severity of security vulnerabilities. It includes:

Base Metrics: Inherent characteristics of a vulnerability (e.g., attack vector, complexity).

Temporal Metrics: Factors that change over time (e.g., exploit availability).

Environmental Metrics: Customization based on an organization's environment.

Correct answers:

Helping to prioritize remediation based on threat context (Option B):

CVSS scores help organizations prioritize vulnerabilities based on real-world impact.

The Environmental metric allows customization based on business risk.

Providing information on attack complexity and vector (Option D):

CVSS Base scores define attack complexity (e.g., low vs. high) and attack vector (e.g., network vs. physical).

This helps security teams understand how a vulnerability can be exploited.

Incorrect options:

Option A (Providing remediation details): CVSS does not include remediation steps; it only scores severity.

Option C (Proof-of-concept exploit links): CVSS scores are not based on specific exploits.

Option E (Compliance information): CVSS focuses on technical risk, not regulatory compliance.

Option F (Adding risk levels to assets): CVSS evaluates individual vulnerabilities, not asset risk classification.
