                                  CompTIA Cybersecurity Analyst (CySA+) Certification Exam 認定 CS0-004 試験問題 (Q65-Q70):

                                  質問 # 65
                                  A security analyst is handling vulnerability management tasks and reviewing the following output from Recon-ng's Shodan-IP module:

                                  Which of the following are the greatest vulnerabilities? (Choose two.)

                                  正解：A、C

                                  解説：
                                  The output reveals sensitive systems such as a domain controller, VPN server, HR database, and payroll server. Exposing these systems to the WAN increases the attack surface and makes critical infrastructure directly discoverable by external attackers.
                                  The systems are also located within the same subnet range (177.511.10.x), indicating that critical data and sensitive services are concentrated on the same network segment. This can facilitate lateral movement and increase the impact of a compromise.


                                  質問 # 66
                                  Two organizations are assessing a partnership to exchange security information and share resources in case an incident occurs. The assessment is in the pre-contract stage, and no detailed definitions have been made by management. Which of the following is the best artifact to formalize the agreement at the current stage?

                                  正解：D

                                  解説：
                                  A Memorandum of Understanding (MOU) is used during the early stages of a partnership to document the intent of the parties to cooperate and outline high-level roles, expectations, and objectives. It is appropriate when detailed contractual terms, service commitments, and operational definitions have not yet been established.


                                  質問 # 67
                                  A compliance analyst works with a management team to develop remediation plans following a recent red-team assessment of the organization's operational technology (OT) networks within an industrial facility. While the backbone of the OT network is based on modern, fully supported infrastructure, the OT components are outdated and vulnerable to a variety of attacks. Further mitigation is not possible from a logical controls perspective. Which of the following approaches is best for the organization to consider for ongoing risk mitigation efforts?

                                  正解：B

                                  解説：
                                  Network segmentation isolates vulnerable systems from other parts of the network, reducing the ability of attackers to move laterally or reach critical systems. In environments where outdated operational technology cannot be easily patched or protected with additional logical controls, segmentation is an effective mitigation strategy because it limits exposure and confines potential compromises to smaller, controlled network zones.


                                  質問 # 68
                                  A security analyst isolates a Windows 11 workstation from the network after known malware is detected. The list of security information and event management (SIEM) events during the malware installation and timeline does not identify a specific user who was logged in. The security analyst uses the local administrative account to log in and would like a list of logins to the machine.
                                  Which of the following PowerShell commands should the analyst use?

                                  正解：B

                                  解説：
                                  Windows Security Event ID 4624 records a successful logon session. Therefore, querying the Security log for event 4624 provides the analyst with historical evidence of successful logins to the affected workstation.
                                  Get-WinEvent is the appropriate PowerShell cmdlet for retrieving Windows event records. The FilterHashtable parameter allows efficient server-side filtering using attributes such as LogName and ID, rather than retrieving an entire event log and filtering the results afterward. Microsoft specifically documents LogName and ID as valid FilterHashtable keys and recommends this approach for efficient event-log querying.
                                  The command then uses Sort-Object TimeCreated -Descending so the newest login events appear first, and Export-Csv preserves the resulting records for investigation.
                                  Option A does not use the correct PowerShell event-query syntax shown. Options C and D search inappropriate log channels and unrelated event IDs. The evidence needed is authentication history, making the Windows Security log and successful-logon identifier 4624 the correct combination.

                                  質問 # 69
                                  An analyst reviews the following log entries:

                                  Which of the following conclusions should the analyst reach? (Choose two.)

                                  正解：A、D

                                  解説：
                                  ws-57 connects to many common service ports on dc-1 within seconds, indicating a port scan. It also uses HTTPS over port 53, which is a non-standard port for HTTPS.
