312-38 Exam Dumps : Certified Network Defender (CND)

The zero-trust model is a security concept centered on the belief that organizations should not automatically trust anything inside or outside its perimeters and instead must verify anything and everything trying to connect to its systems before granting access. The Software Defined Perimeter (SDP) aligns with this model by creating a dynamic, context-aware, and secure boundary around network resources. SDP controls access to resources based on identity, authentication, and authorization, ensuring that only authenticated and authorized users or systems can access the services they require. This approach minimizes the attack surface by hiding network resources from unauthorized or unauthenticated users, which is a core principle of zero-trust security.

References: The information aligns with the principles of zero-trust security as outlined in the NIST 800-207 standard for Zero Trust1 and is supported by the Cloud Security Alliance’s documentation on Software-Defined Perimeter (SDP) and Zero Trust2. Additionally, the relationship between SDP and zero-trust is discussed in various industry sources, highlighting SDP as an architecture that enables the zero-trust model by providing secure and authenticated access to network resources34.

Containers are designed to be lightweight, running directly within the host’s kernel without the need for a guest operating system. This means they share the same OS kernel but maintain separate user spaces. While this architecture provides process-level isolation, it does not offer the same level of security as a fully isolated virtual machine (VM). VMs include a full copy of an operating system, a virtual copy of the hardware that the OS requires to run, and provide complete isolation from the host system. Containers, on the other hand, are less secure because if the host OS is compromised, all containers could potentially be compromised. The Certified Network Defender (CND) program emphasizes understanding the security implications of different technologies, including containers, and the importance of implementing appropriate security measures to protect network resources123.

 Organized hackers are professional cybercriminals who often work in groups and are motivated by financial gain. They are known for their skills and the ability to carry out sophisticated attacks on systems for profit. Unlike script kiddies, who lack advanced skills and typically use readily available tools, organized hackers use custom-developed tools and methods. Hacktivists are motivated by political or social causes, and cyber terrorists aim to use cyber attacks to create fear or political change, not necessarily for profit.

References: The EC-Council’s Certified Network Defender (CND) program covers various types of cyber threats and the motivations behind them, including the distinction between different types of hackers and their objectives. The CND curriculum includes understanding the threat landscape, which encompasses organized hackers and their profit-driven attacks12.
