Cisco Certified Support Technician (CCST) CybersecurityVulnerability ManagementEasy
A cybersecurity analyst is reviewing a vulnerability scan report that lists several high-severity vulnerabilities related to outdated software versions on critical servers. The analyst needs to prioritize which vulnerabilities to address first given limited resources and a strict compliance deadline. Which of the following factors is MOST critical in determining the immediate remediation priority?
- AThe vendor's recommended patch release date for each vulnerability.
- BThe number of affected systems across the network.
- CThe availability of a workaround that doesn't require a software update.
- DThe ease of exploitation and potential impact on business operations.
Show answer & explanationAnswer & explanation
Correct answer: D. The ease of exploitation and potential impact on business operations.
Prioritization in vulnerability management is primarily driven by the risk a vulnerability poses, which is a combination of its likelihood of exploitation (ease of exploitation) and the damage it could cause (potential impact on business operations).
Why the other options are wrong
- A. While important, the vendor's patch release date doesn't directly indicate the immediate risk or impact to the organization.
- B. The number of affected systems is a factor, but a single critical system with a high-impact, easily exploitable vulnerability might be more urgent than many systems with low-impact vulnerabilities.
- C. Workarounds are remediation options, but the availability of one doesn't dictate the initial prioritization of the vulnerability itself.
Vulnerability Prioritization
The process of ranking vulnerabilities based on their risk to an organization, considering factors like severity, exploitability, and business impact to allocate remediation resources effectively.
- Focuses on risk: impact x likelihood.
- Guides resource allocation.
- Often involves CVSS scores, threat intelligence, and asset criticality.
