CompTIA Cybersecurity Analyst (CySA+) Certification Exam 認定 CS0-003 試験問題 (Q327-Q332):

質問 # 327
Law enforcement subpoenas a company in order to obtain all records related to the activities a threat actor performed using the IP address 154.21.154.21. Which of the following should an analyst perform first?

正解：B

解説：
A legal hold should be established first to ensure that all relevant records, logs, and evidence related to the investigation are preserved and protected from deletion or modification. Once preservation requirements are in place, evidence can be collected and handled according to forensic and legal procedures.


質問 # 328
Which of the following is a reason why proper handling and reporting of existing evidence are important for the investigation and reporting phases of an incident response?

正解：B

解説：
The correct answer is A. To ensure the report is legally acceptable in case it needs to be presented in court.
Proper handling and reporting of existing evidence are important for the investigation and reporting phases of an incident response because they ensure the integrity, authenticity, and admissibility of the evidence in case it needs to be presented in court. Evidence that is mishandled, tampered with, or poorly documented may not be accepted by the court or may be challenged by the opposing party. Therefore, incident responders should follow the best practices and standards for evidence collection, preservation, analysis, and reporting1.
The other options are not reasons why proper handling and reporting of existing evidence are important for the investigation and reporting phases of an incident response. They are rather outcomes or benefits of conducting a thorough and effective incident response process. A lessons-learned analysis (B) is a way to identify the strengths and weaknesses of the incident response team and improve their performance for future incidents. A postmortem analysis is a way to determine the root cause, impact, and timeline of the incident and provide recommendations for remediation and prevention. A root cause analysis (D) is a way to identify the underlying factors that led to the incident and address them accordingly.


質問 # 329
An analyst views the following log entries:

The organization has a partner vendor with hosts in the 216.122.5.x range. This partner vendor is required to have access to monthly reports and is the only external vendor with authorized access. The organization prioritizes incident investigation according to the following hierarchy: unauthorized data disclosure is more critical than denial of service attempts.
which are more important than ensuring vendor data access.
Based on the log files and the organization's priorities, which of the following hosts warrants additional investigation?

正解：A

解説：
The correct answer is A. 121.19.30.221.
Based on the log files and the organization's priorities, the host that warrants additional investigation is
121.19.30.221, because it is the only host that accessed a file containing sensitive data and is not from the partner vendor's range.
The log files show the following information:
The IP addresses of the hosts that accessed the web server
The date and time of the access
The file path of the requested resource
The number of bytes transferred
The organization's priorities are:
Unauthorized data disclosure is more critical than denial of service attempts Denial of service attempts are more important than ensuring vendor data access According to these priorities, the most serious threat to the organization is unauthorized data disclosure, which occurs when sensitive, protected, or confidential data is copied, transmitted, viewed, stolen, altered, or used by an individual unauthorized to do so123. Therefore, the host that accessed a file containing sensitive data and is not from the partner vendor's range poses the highest risk to the organization.
The file that contains sensitive data is /reports/2023/financials.pdf, as indicated by its name and path. This file was accessed by two hosts: 121.19.30.221 and 216.122.5.5. However, only 121.19.30.221 is not from the partner vendor's range, which is 216.122.5.x. Therefore, 121.19.30.221 is a potential unauthorized data disclosure threat and warrants additional investigation.
The other hosts do not warrant additional investigation based on the log files and the organization's priorities.
Host 134.17.188.5 accessed /index.html multiple times in a short period of time, which could indicate a denial of service attempt by flooding the web server with requests45. However, denial of service attempts are less critical than unauthorized data disclosure according to the organization's priorities, and there is no evidence that this host succeeded in disrupting the web server's normal operations.
Host 202.180.1582 accessed /images/logo.png once, which does not indicate any malicious activity or threat to the organization.
Host 216.122.5.5 accessed /reports/2023/financials.pdf once, which could indicate unauthorized data disclosure if it was not authorized to do so. However, this host is from the partner vendor's range, which is required to have access to monthly reports and is the only external vendor with authorized access according to the organization's requirements.
Therefore, based on the log files and the organization's priorities, host 121.19.30.221 warrants additional investigation as it poses the highest risk of unauthorized data disclosure to the organization.


質問 # 330
A DevOps analyst implements a webhook to trigger code vulnerability scanning for submissions to the repository. Which of the following is the primary benefit of this enhancement?

正解：D

解説：
Automating vulnerability scanning with a webhook ensures that every code submission is automatically scanned for vulnerabilities, increasing coverage and reducing the chance of unscanned, vulnerable code entering the repository.


質問 # 331
Which of the following is often used to keep the number of alerts to a manageable level when establishing a process to track and analyze violations?

正解：B

解説：
A threshold value is a parameter that defines the minimum or maximum level of a metric or event that triggers an alert. For example, a threshold value can be set to alert when the number of failed login attempts exceeds 10 in an hour, or when the CPU usage drops below 20% for more than 15 minutes. By setting a threshold value, the process can filter out irrelevant or insignificant alerts and focus on the ones that indicate a potential problem or anomaly. A threshold value can help to reduce the noise and false positives in the alert system, and improve the efficiency and accuracy of the analysis12
