質問 # 504
Assume that you are working as a network administrator in the head office of a bank. One day a bank employee informed you that she is unable to log in to her system. At the same time, you get a call from another network administrator informing you that there is a problem connecting to the main server. How will you prioritize these two incidents?
正解：B
解説：
Prioritizing incidents in a network environment, especially within a critical infrastructure like a bank, should be based on the potential technical effect of the incident. This approach ensures that the most severe and impactful issues are addressed first to maintain business continuity and minimize potential damage. The incident involving the main server would likely take precedence because it could affect a larger number of systems and operations within the bank, compared to an individual's login issue. The ITIL framework supports this prioritization method by emphasizing the importance of impact and urgency when managing network incidents12. References: The prioritization strategy aligns with best practices outlined in the ITIL framework for IT service management, which suggests managing incidents based on their severity, urgency, and impact on business operations12.

Which Internet access policy starts with all services blocked and the administrator enables safe and necessary services individually, which provides maximum security and logs everything, such as system and network activities?
正解：C
解説：
The Paranoid policy is an Internet access policy that begins with the premise that all services are blocked by default. Under this policy, the administrator must explicitly enable each service that is deemed safe and necessary. This approach ensures maximum security as it minimizes the potential attack surface by not allowing any services unless they have been vetted and approved. Additionally, this policy typically involves extensive logging of all system and network activities, which can be crucial for monitoring, auditing, and forensic purposes.
References: The concept of a Paranoid policy aligns with the best practices for securing network environments, as it emphasizes a default-deny stance and careful control over network services. This information is consistent with the objectives of the Certified Network Defender (CND) program, which advocates for stringent access controls and detailed logging to protect information systems. For the most current and detailed information, please refer to the latest Certified Network Defender (CND) documents and study guides from the EC-Council1.
質問 # 506
Sean has built a site-to-site VPN architecture between the head office and the branch office of his company. When users in the branch office and head office try to communicate with each other, the traffic is encapsulated. As the traffic passes though the gateway, it is encapsulated again. The header and payload both are encapsulated. This second encapsulation occurs only in the
__________implementation of a VPN.
正解：D
解説：
In the context of VPNs, when both the header and payload of traffic are encapsulated, it indicates the use of Tunnel Mode. This mode is typically employed in site-to-site VPNs where the entire IP packet is wrapped with a new IP header. Tunnel Mode is designed to secure traffic between different networks over the internet, making it suitable for connecting multiple sites of an organization. Unlike Transport Mode, which only encrypts the payload and leaves the original IP header intact, Tunnel Mode encrypts the entire IP packet and adds a new header, which allows for the secure passage of the traffic through untrusted networks.
質問 # 507
You are an Administrator for a network at an investment bank. You are concerned about individuals breeching your network and being able to steal data before you can detect their presence and shut down their access.
Which of the following is the best way to address this issue?
正解：D
解説：
A honey pot is designed to attract intruders to a false server that has no real data (but may seem to have valuable data). The specific stated purpose of a honey pot is as a backup plan in case an intruder does gain access to your network.
Answer option B is incorrect. The firewall may help reduce the chance of an intruder gaining access, but won't help protect you once they have gained access.
質問 # 508
Sam, a security analyst, is tasked with updating the organization's continuity documentation. He starts by identifying core functions, estimating their downtime tolerance, and assessing the financial impact of service interruptions. This helps him determine which operations must resume first during a disruption. Which BCP process is Sam performing?
正解：B
解説：
Business Impact Analysis identifies critical business functions, determines the acceptable downtime for each process, and evaluates the operational and financial consequences of service disruptions. This analysis prioritizes which operations must be restored first during a disruption and provides the foundation for developing recovery strategies in a business continuity plan.
