CompTIA Cybersecurity Analyst (CySA+) Certification Exam 認定 CS0-004 試験問題 (Q70-Q75):

質問 # 70
Which of the following will most likely help decrease false positives?

A. Threat hunting
B. Alert tuning
C. Automating escalation
D. A security operations center (SOC) dashboard

正解：B

解説：
Alert tuning refines detection rules and thresholds based on environment-specific behavior, reducing noise and eliminating unnecessary or incorrect alerts, which directly decreases false positives.

質問 # 71
A security team reviews a penetration testing report of a web application that contains multiple cross-site scripting (XSS) and Structured Query Language injection (SQLi) vulnerabilities.
Which of the following is most likely causing these to occur?

A. Misconfigured web application firewall (WAF)
B. Lack of endpoint protection in the environment
C. Lack of a Hypertext Transfer Protocol (HTTP) Strict Transport Security (HSTS) header
D. Lack of secure input validation

正解：D

解説：
The common underlying weakness is insufficient handling and validation of untrusted application input .
XSS occurs when attacker-controlled content is processed and subsequently rendered in a manner that allows script execution. SQL injection occurs when untrusted values become part of database commands without appropriate separation between code and data.
OWASP recommends validating untrusted input early in the processing workflow and applying syntactic and semantic validation. For SQL injection specifically, OWASP identifies parameterized queries as the primary defensive technique and recommends allow-list input validation as an additional defensive layer. For XSS, context-appropriate output encoding and sanitization must also be applied; therefore input validation should be viewed as part of secure application handling rather than the sole technical control.
A WAF can provide defense in depth but does not correct vulnerable application code. HSTS forces browsers to use HTTPS and protects transport security; it does not prevent malicious input from being interpreted by an application. Endpoint protection similarly operates on hosts and does not repair web application data-handling flaws.

質問 # 72
A vulnerability analyst runs a credentialed vulnerability scan covering all addressable enterprise assets. After running the scan, the analyst discovers a large number of critical vulnerabilities that cannot be immediately remediated. Which of the following are the most likely reasons why the vulnerabilities cannot be immediately addressed?

A. Physical access challenges, the absence of vendor support, and a lack of system documentation
B. Legacy and proprietary systems, a lack of patch availability, and vendor dependencies
C. Lack of technical skills, the absence of a test environment, and the absence of an asset inventory
D. Inaccurate asset inventory, a lack of system documentation, and an absence of authorization

正解：B

解説：
Legacy or proprietary systems may not support current patches, fixes may not yet exist, and remediation may depend on vendor testing or approval.

質問 # 73
An incident response manager conducts a tabletop exercise. Which of the following steps should the incident response manager take next?

A. Root cause analysis
B. Lessons learned
C. Containment
D. Response

正解：B

解説：
After completing a tabletop exercise, the next step is to review the exercise outcomes and identify gaps, strengths, and areas for improvement in the incident response process. This lessons- learned phase helps refine procedures, update playbooks, and improve the organization's preparedness for real incidents.

質問 # 74
Cybersecurity analysts determine that SIEM alerts are true positives and an internal application is being attacked. Which of the following is a critical step to understanding the impact on the business at this stage?

A. Root cause analysis
B. Knowledge of any regulatory requirements
C. Notification of the legal team
D. Identification of stakeholders

正解：D

解説：
Identifying stakeholders is critical for understanding the business impact of an attack because stakeholders can provide information about the application's role, the business processes it supports, the data it handles, and the operational consequences of disruption. This information helps determine the severity and scope of the incident and guides response priorities.
