312-38 Exam Dumps - ECCouncil CND Questions and Answers

Storage device virtualization is the correct answer because it involves abstracting physical storage resources into a pool of storage that can be managed centrally and allocated to different virtual machines. This level of virtualization allows for the creation of a massive pool of storage areas that are not tied to a single physical device, providing flexibility and scalability in managing storage resources for various virtual machines running on the hardware.

References: The information aligns with the objectives and documents of the EC-Council’s Certified Network Defender (CND) program, which covers various aspects of network security, including virtualization and storage strategies as part of a comprehensive defense approach12.

The Cloud Carrier acts as an intermediary that provides connectivity and transport services between cloud consumers and cloud providers. They are responsible for ensuring that the cloud services are accessible to consumers via network, telecommunication, and other access services. This role is crucial in the cloud ecosystem as it facilitates the movement of data and services across the internet or other networks, making the cloud services available to users and organizations.

References: The role of the Cloud Carrier is discussed in various cloud computing resources. For example, Quizlet’s flashcards on “Chapter 9 - security in cloud computing” describe the Cloud Carrier as an intermediary providing connectivity and transport of cloud services from cloud providers to cloud consumers1. Similarly, the Cloud Accountability Project’s reference architecture outlines the Cloud Carrier’s role in transporting cloud services2. BMC Software’s blog also highlights the Cloud Carrier’s role in providing the necessary bandwidth and capabilities to connect consumers with providers3.

In the context of password hashes on a Windows 7 computer, a Rainbow Table attack is a feasible method an attacker might use to reveal passwords. This type of attack utilizes precomputed tables known as rainbow tables that contain hash values for every possible combination of characters. An attacker with access to password hashes can use these tables to look up the corresponding plaintext passwords. The effectiveness of rainbow tables stems from their ability to reverse cryptographic hash functions, which are used to store passwords securely. Since Windows 7 uses NTLM hashes, which are known to be vulnerable to rainbow table attacks, this method is particularly relevant12.

References: The explanation draws upon the known vulnerabilities of NTLM hash functions in Windows 7 and the general principles of rainbow table attacks as discussed in security literature12.

The Docker Daemon is responsible for managing Docker images, containers, networks, and storage volumes, as well as processing requests from the Docker API. The Docker daemon (dockerd) listens for Docker API requests and manages these Docker objects1. It is a background service that manages the Docker containers and handles the container life cycle, which includes running, stopping, and deleting containers. It also manages networking for the containers and the storage volumes that containers use.

References: The explanation provided is based on the official Docker documentation, which outlines the responsibilities and functionalities of the Docker daemon in the context of container management1.

The mobile-use approach that allows an organization’s employees to use devices they are comfortable with and that best fit their preferences and work purposes is Bring Your Own Device (BYOD). This approach offers the most flexibility for employees, as they can bring and use their personal devices for work-related activities. It is a popular choice for companies that wish to provide a flexible work environment and cater to the diverse preferences of their employees123.

References: The concept of BYOD and its implications on workplace flexibility and employee preferences are well-documented in enterprise mobility management literature and align with the Certified Network Defender (CND) course’s objectives regarding understanding and managing mobile device security within an organization123.

An Intrusion Detection System (IDS) is designed to monitor network or system activities for malicious actions or policy violations. The correct order of activities that an IDS follows to detect an intrusion starts with Intrusion Monitoring, where it observes the network traffic or system events. Following this, Intrusion Detection takes place, where the IDS analyzes the monitored data to identify potential security breaches. Once a potential intrusion is detected, the Response mechanism is activated to address the intrusion, which may include alerts or automatic countermeasures. Finally, Prevention is applied to improve the system’s defenses against future intrusions based on the detected patterns and responses.

References: This explanation is based on the standard operational procedure of IDS as per the Network Defender (CND) objectives and documents1.

John should implement a Proactive security approach. This approach is part of the adaptive security strategy that is built on a 4-pronged approach — Protect, Detect, Respond, and Predict1. By being proactive, John can anticipate potential threats and vulnerabilities and take steps to mitigate them before they can be exploited. This is in contrast to reactive or retrospective approaches, which deal with threats after they have occurred. The proactive approach is aligned with the Certified Network Defender (CND) program’s emphasis on preparing network defenders to identify parts of an organization that need to be reviewed and tested for security vulnerabilities, and how to reduce, prevent, and mitigate risks in the network2345.

 According to standard IoT security practices, an IoT Gateway should be connected to a border router. This setup is recommended because a border router acts as a gateway between different networks, managing the traffic between these networks and the internet. It provides an additional layer of security, ensuring that the IoT devices and the internal network are protected from external threats. The border router can implement security measures such as firewalls, intrusion detection systems, and data encryption to safeguard the IoT ecosystem.

References: The standard practice of connecting an IoT Gateway to a border router is supported by security guidelines that emphasize the importance of segregating IoT devices from internal networks to prevent potential cyber threats from spreading across networks123.

In the context of network security, ICMP fingerprinting is a technique used to determine the operating system of a target machine by analyzing its responses to ICMP requests. The correct filter to detect unusual ICMP requests that could be indicative of ICMP probes from an attacker is option C. This filter looks for ICMP echo requests (type 8) that do not have a corresponding echo reply (code 0). Since the code for an echo request is 0, the filter (!(icmp.code==8)) is used to exclude other ICMP messages with different codes.

References: The use of Wireshark filters to identify specific types of ICMP traffic is a common practice in network analysis. The Certified Network Defender (CND) course material covers various network monitoring tools and techniques, including the analysis of ICMP traffic for security purposes1. Additionally, resources like Wireshark documentation and network security forums provide practical examples of filters used to detect ICMP fingerprinting attempts23.

James should use the Wireshark filter icmp.type==8 or icmp.type==0 to detect a PING sweep attack. This filter will capture both ICMP echo requests and echo replies, which are used in PING sweeps to discover active hosts on a network. When conducting a PING sweep, an attacker sends ICMP echo requests (type 8) to multiple hosts and listens for echo replies (type 0). By monitoring for both types, James can effectively identify a PING sweep attack.

References: The use of this filter for detecting PING sweeps is documented in various network security resources, including the InfosecMatter guide on detecting network attacks with Wireshark1, which specifically lists icmp.type==8 or icmp.type==0 as the filter for ICMP ping sweeps. This approach is consistent with standard practices for network monitoring and intrusion detection.
