質問 # 55
Which of the following is a preventive control that can help in reducing the risk of future incidents?
- A. Conducting periodic employee training on incident response
- B. Creating secure backups of critical data
- C. Regularly updating antivirus signatures
- D. Implementing strong access controls and authentication mechanisms
正解：D
解説：
Implementing strong access controls and authentication mechanisms is a preventive control that can help reduce the risk of future incidents. By ensuring that only authorized individuals have access to systems and data, the likelihood of unauthorized access or malicious activity is minimized. While regularly updating antivirus signatures, conducting employee training, and creating secure backups are also important preventive measures, the focus here is on access controls and authentication mechanisms.
質問 # 56
Which of the following best describes an Advanced Persistent Threat (APT)?
- A. An unintentional and harmless interaction with a computer system
- B. A type of malware designed to disrupt computer networks
- C. A security incident caused by human error or negligence
- D. A targeted cyber attack that aims to gain unauthorized access to sensitive information
正解：D
解説：
An APT is a sophisticated and ongoing cyber attack by threat actors with the objective of gaining unauthorized access to sensitive information or networks. Unlike traditional attacks, APTs are stealthy and persistent, often targeting specific organizations or individuals for an extended period of time.
質問 # 57
When should a firewall rule triggering block external access to a network resource be escalated?
- A. Only if the access was authorized.
- B. Only if the access attempt is from a known malicious IP address.
- C. Always, regardless of authorization.
- D. Never, as it is a normal security function of a firewall.
正解：D
解説：
Blocking external access to a network resource is a normal security function of a firewall and does not necessarily require escalation. Firewalls are designed to monitor and control incoming and outgoing network traffic based on predetermined rules and configurations. However, if the rule is triggered unexpectedly or causes disruption to critical services, it may be appropriate to escalate the issue for further investigation or adjustment of the firewall rule.

質問 # 62
What is privilege escalation in the context of cybersecurity?
- A. The act of elevating one's user account privileges to gain higher levels of access
- B. The process of gaining unauthorized access to a system
- C. The technique used to bypass firewall protections
- D. The method of stealing sensitive information from a compromised system
正解：A
解説：
Privilege escalation refers to the process of gaining higher levels of access or permissions than originally authorized. This can be achieved by exploiting vulnerabilities or weaknesses in a system, such as a software flaw or misconfiguration. By escalating privileges, an attacker can gain more control and access to sensitive data or critical system resources. It is a serious security concern and is commonly used by attackers to broaden their scope of unauthorized activities within a compromised system or network. Implementing strong access controls and regular security updates can help mitigate the risk of privilege escalation.
質問 # 63

- B. To monitor and analyze network traffic for potential security threats.
- C. To protect against viruses and malware.
- D. To secure wireless networks from unauthorized access.
正解：A
解説：
A Virtual Private Network (VPN) is a network technology that allows users to securely connect to a private network from a remote location over a public network, such as the internet. It establishes a secure tunnel between the user's device and the private network, encrypting the data and ensuring confidentiality and integrity.
質問 # 64
Which of the following is an example of a network vulnerability?
- A. Implementing a firewall
- B. Using a strong password
- C. Encrypting sensitive data
- D. Running outdated and unpatched software
