ECCouncil 312-38 Actual Questions

 The topology that the network designer will propose is known as a screened subnet. This topology involves the use of two or more firewalls to create a network segment referred to as a demilitarized zone (DMZ). The DMZ acts as a buffer zone between the public internet and the internal network. It contains the public-facing servers, such as the web portal mentioned, which is isolated from the internal network for added security. The screened subnet topology typically includes a firewall at the network’s edge connected to the internet, another firewall separating the DMZ from the internal network, and the DMZ itself. This setup allows for strict control of traffic between the internet, the DMZ, and the internal network, providing an additional layer of security.

References: The concept of a screened subnet as a network topology is consistent with the Certified Network Defender (CND) course materials, which cover network perimeter security and the implementation of firewalls to protect networked systems12.

In Linux, to disable a user account, the usermod command is used with the -L option. This option locks the user’s password, effectively disabling the account by preventing the user from logging in. The command usermod -L alice will lock the user ‘alice’ by adding an exclamation mark (!) in front of the encrypted password in the /etc/shadow file, which is the standard method for disabling an account in Linux.

References: This information is consistent with standard Linux administration practices and is also in line with the objectives of the EC-Council’s Certified Network Defender (CND) program, which includes understanding and managing user accounts and permissions as part of network security1.

A System Specific Security Policy (SSSP) is focused on the implementation and configuration of technology and the behavior of users interacting with that specific system. It provides detailed, targeted guidance on how systems should be configured and used securely. This type of policy is often more technical than other policies and includes requirements for system configuration, connections to other systems, and processing and handling of data. It also addresses user responsibilities and expected behavior when using the system.

References: The concept of a System Specific Security Policy is consistent with the EC-Council’s Certified Network Defender (CND) curriculum, which includes understanding and applying security policies that are specific to systems as part of a comprehensive network defense strategy123.

Ross implemented Discretionary Access Control (DAC) in the organization’s peer-to-peer network. DAC is a type of access control where the data owner has the authority to decide who can access their data and what permissions they have. In a peer-to-peer network, where each peer can act as both a client and a server, DAC allows individual users to set access controls for their own files and folders. This is consistent with Ross allowing employees to set their own control measures, which aligns with the principles of DAC where owners or creators of the resources have the discretion to grant or restrict access to other users based on their own criteria1.

References: The explanation aligns with the standard definitions and functions of Discretionary Access Control as outlined in cybersecurity resources such as Built In’s guide to DAC1 and is in accordance with the Certified Network Defender (CND) program’s objectives regarding understanding and implementing access control measures.
