Report
Export

Due to budget constraints, an organization created a policy that only permits vulnerabilities rated high and critical according to CVSS to be fixed or mitigated. A security analyst notices that many vulnerabilities that were previously scored as medium are now breaching higher thresholds. Upon further investigation, the analyst notices certain ratings are not aligned with the approved system categorization. Which of the following can the analyst do to get a better picture of the risk while adhering to the organization's policy?

A.
Align the exploitability metrics to the predetermined system categorization.
Answers
A.
Align the exploitability metrics to the predetermined system categorization.
B.
Align the remediation levels to the predetermined system categorization.
Answers
B.
Align the remediation levels to the predetermined system categorization.
C.
Align the impact subscore requirements to the predetermined system categorization.
Answers
C.
Align the impact subscore requirements to the predetermined system categorization.
D.
Align the attack vectors to the predetermined system categorization.
Answers
D.
Align the attack vectors to the predetermined system categorization.
Suggested answer: C

Explanation:

Aligning the impact subscore requirements to the predetermined system categorization can help the analyst get a better picture of the risk while adhering to the organization's policy. The impact subscore is one of the components of the CVSS base score, which reflects the severity of a vulnerability. The impact subscore is calculated based on three metrics: confidentiality, integrity, and availability. These metrics can be adjusted according to the system categorization, which defines the security objectives and requirements for a system based on its potential impact on an organization's operations and assets. By aligning the impact subscore requirements to the system categorization, the analyst can ensure that the CVSS scores reflect the true impact of a vulnerability on a specific system and prioritize remediation accordingly.
