312-38 Exam Dumps - ECCouncil CND Questions and Answers

The correct commands to update the respective Linux distributions are as follows:

• Red Hat: Uses the yum command or the newer dnf command for package management and updates.
• Fedora: Originally used yum but now has transitioned to dnf as the default package manager.
• Debian: Utilizes the apt-get command for package management tasks, including updates.

The matching from the options provided would be:

• 1-v: Slackware based systems use Autoupdate.
• 2-iii: RPM-based systems, which include Fedora, use Swaret.
• 3-i: Debian based systems use apt-get.
• 4-iv: Red Hat based systems use up2date.

References: This information is based on general knowledge of Linux distribution package managers and their respective update commands. For the most accurate and detailed information, please refer to the official documentation of each Linux distribution and the Certified Network Defender (CND) study materials provided by the EC-Council1.

The Security Reference Monitor (SRM) is the core component in Windows operating systems responsible for controlling access to resources. It enforces security policies and checks whether a user’s request to access a resource is allowed by the system’s security policy. SRM operates in the kernel mode and ensures that access rights and permissions are properly enforced, making it a critical part of the Windows security architecture for resource access control.

References: The role of SRM in Windows security is well-documented and aligns with the information provided in Microsoft’s official documentation and security model, which describes SRM as the component that enforces access controls and security policies within the system12.

The Path rule is used to specify a path to a folder or application and control access based on that path. By setting a Path rule, an administrator can disallow a system or user from accessing all applications except for those located in a specified folder. This is particularly useful for creating a secure environment where users can only run applications from a trusted location, thereby preventing the execution of unauthorized or potentially harmful programs.

References: This explanation is consistent with the principles of application whitelisting and access control in network security, as outlined in the Certified Network Defender (CND) course materials and objectives, which emphasize the importance of controlling access to system resources to protect against threats.

The Internet Control Message Protocol (ICMP) operates at the network layer and is integral to the Internet Protocol suite. It is utilized primarily for error handling during packet delivery, such as informing senders of a failed delivery due to unreachable destinations or other path-related issues. ICMP is also used for diagnostic purposes, with tools like ping and traceroute relying on ICMP messages to test connectivity and trace packet routes. Unlike transport layer protocols like TCP or UDP, ICMP does not establish a connection before sending messages, making it a connectionless protocol. This characteristic allows ICMP to quickly relay error messages and network information without the overhead of establishing a session.

References: The role and functions of ICMP are well-documented in resources such as GeeksforGeeks, ExploringBits, and IBM’s TCP/IP concepts, which align with the ECCouncil’s Network Defender (CND) objectives and documents123.

The log entry %ASA-6-11008 indicates that the message is of a severity level 6, which corresponds to an informational message. In the context of Cisco ASA Firewall logs, severity levels range from 0 (emergency) to 7 (debugging), with lower numbers indicating higher severity. A severity level of 6 is used for messages that provide information about normal but significant events. In this case, the log indicates that a user named ‘enable_16’ executed the ‘configure term’ command, which is a noteworthy event but does not indicate an error or critical condition.

References: This interpretation is based on the Cisco Secure Firewall ASA Series Syslog Messages documentation, which outlines the different severity levels and their meanings1.

When a Trojan is suspected to have infected a computer, the first course of action should be to contain the damage to prevent the malware from spreading or causing further harm. This involves disconnecting the infected device from the network to isolate it and prevent the Trojan from communicating with potential command and control servers or infecting other systems123.

While informing the Incident Response Team (IRT) and other members of the organization is also important, these actions come after the immediate threat has been contained. Therefore, the correct answer is to contain the damage (A), which aligns with the Certified Network Defender (CND) objectives that prioritize immediate containment to minimize the impact of security incidents45678.

References: The response is based on best practices for dealing with Trojans as outlined in network security and incident response guidelines, including those from the EC-Council’s Certified Network Defender (CND) program. The CND framework emphasizes the importance of quick containment to protect network integrity and prevent further damage45678.

 The Encapsulating Security Payload (ESP) component of IPsec is designed to provide confidentiality for the content of packets. ESP encrypts the data payload of IP packets to ensure that the information being transmitted remains confidential and cannot be accessed or intercepted by unauthorized parties. This encryption is crucial for protecting sensitive data as it travels across insecure networks, such as the internet.

References: The role of ESP in providing confidentiality within the IPsec protocol is well-documented and aligns with the security objectives of IPsec to protect IP traffic through encryption and other security measures1234.

The netstat -an command is used to display all active connections and listening ports with addresses and port numbers in numerical form. This is particularly useful for administrators who need to quickly identify connections without resolving the hostnames, which can save time and resources, especially when dealing with a large number of connections.

References: The usage of the netstat -an command aligns with the objectives and documents of the Certified Network Defender (CND) course, which emphasizes the importance of understanding and utilizing network commands for effective network security management. The -an switch combines two options: -a displays all connections and listening ports, and -n displays addresses and port numbers in numerical form1.

Script block logging is the PowerShell logging component that records the details of pipeline execution as PowerShell executes, including variable initialization and command invocations. This feature is particularly useful for identifying and recording suspicious scripting activity, as it captures the full content of script blocks as they are executed, providing a detailed audit trail. This level of logging is essential for security forensics and understanding the context of commands executed within the PowerShell environment.

References: The explanation is based on the functionality of PowerShell’s logging capabilities, where script block logging is designed to capture and record detailed information about script execution, which is crucial for security monitoring and incident response1.

The AWS Shared Responsibility Model outlines the security and compliance duties divided between AWS and its customers. AWS is responsible for “Security of the Cloud,” which includes the infrastructure that runs AWS services. The customer is responsible for “Security in the Cloud,” which involves managing the guest operating system, application software, and configuration of the AWS-provided firewall, among other tasks12.

The options A, B, and D are actual components of the AWS Shared Responsibility Model, focusing on container services, infrastructure services, and storage services, respectively. These models define the division of security responsibilities between AWS and the customer for each type of service. However, there is no distinct Shared Responsibility Model for Abstract Services as described in the options. Instead, abstract services fall under the broader categories of Infrastructure as a Service (IaaS), Platform as a Service (PaaS), or Software as a Service (SaaS), each with its own set of shared responsibilities.

References: The information about the AWS Shared Responsibility Model can be found in the official AWS documentation and resources that explain the division of responsibilities and provide guidance on how customers can manage their part of the security and compliance requirements12.
