CompTIA Cybersecurity Analyst (CySA+) Certification Exam 認定 CS0-004 試験問題 (Q78-Q83):

質問 # 78
When vulnerabilities are identified weeks after the disclosure, which of the following KPIs most likely needs to be adjusted?

正解：A

解説：
Mean Time to Detect (MTTD) measures how quickly vulnerabilities or security issues are identified after they become known or occur. If vulnerabilities are being discovered weeks after public disclosure, the organization's detection process is too slow, indicating that the MTTD KPI needs improvement.


質問 # 79
A vulnerability analyst must perform a security assessment on an edge device running various services. The analyst runs an Nmap port scan and sees the following output:

Which of the following should the analyst do next to validate the discovered remote access service is secure?

正解：A

解説：
Open UDP port 500 indicates ISAKMP/IKE, commonly used by IPsec VPNs. Main Mode provides a more secure IKE negotiation by protecting peer identity information.


質問 # 80
An analyst reviews the following system logs from a recent breach attempt:

Which of the following techniques did the attacker attempt to use?

正解：D

解説：
The attacker used sudo, su, and linpeas.sh to move from lower-privileged accounts to the root account, demonstrating privilege escalation.


質問 # 81
A Chief Information Security Officer (CISO) evaluates a threat heat map and notices a substantial increase in custom scanning and enumeration activities. The CISO wants to gather as much information as possible about the activities targeting the company to help prioritize mitigations.
Which of the following solutions is the best way to accomplish this goal?

正解：D

解説：
A honeypot is the strongest choice because the objective is not merely to block activity but to collect detailed intelligence about how adversaries are scanning, enumerating, and interacting with the organization. A properly isolated honeypot deliberately presents an attractive target while allowing defenders to observe attacker behavior without exposing legitimate production assets.
The resulting telemetry can reveal source infrastructure, targeted services, enumeration sequences, exploit attempts, command patterns, tools, payloads, and potentially broader TTPs. MITRE D3FEND defines a decoy environment as hosts and networks established specifically to deceive an attacker, and describes honeypots as decoy network resources that can expose an attacker's potential intent and strategy.
Canary tokens are valuable high-confidence tripwires but generally provide narrower detection evidence.
Threat-intelligence subscriptions provide external intelligence and may help with prioritization, yet they will not provide the same organization-specific visibility into actors actively interacting with the company's exposed environment. A WAF can log web attacks and block malicious requests, but its visibility is primarily limited to web application traffic.

質問 # 82
A security analyst IS comparing the results of the past and current active credentialed vulnerability scans:
Past scan:

Current scan:

Which of the following should the analyst do next?

正解：A

解説：
The current scan shows that a previously low-severity SSL vulnerability has increased to a high- severity (9.1) issue with potential information disclosure. This means the organization now faces a significantly greater risk than before. Management must be informed because the company's assets could be leveraged in attacks or suffer data exposure, and leadership needs awareness to prioritize remediation.
