Pass the ECCouncil CND 312-38 Questions and answers with CertsForce

The countermeasures to deal with future malware incidents involve a multi-layered approach that includes:

Complying with the company’s security policies: Ensuring that all security policies are followed can prevent malware incidents by maintaining a secure network environment.

Implementing strong authentication schemes: Strong authentication can prevent unauthorized access, reducing the risk of malware being introduced by attackers.

Implementing a strong password policy: Robust password policies can deter attackers by making it more difficult to gain access through brute force or other password-related attacks.

Install antivirus software: Antivirus software is essential for detecting, preventing, and removing malware from the network.

These measures align with the Certified Network Defender (CND) program’s emphasis on a defense-in-depth strategy, which includes protecting endpoints, data, and networks, as well as continuous threat monitoring and response123.

The Birthday Attack is a type of cryptographic attack that exploits the mathematics behind the birthday problem in probability theory. This attack is relevant to the question as it involves attacking cryptographic hash functions based on the probability of collisions. In the context of hash functions, a collision occurs when two different inputs produce the same hash output. The Birthday Attack leverages the fact that in a set of randomly chosen keys, it is probable that two keys will have the same hash value. This is analogous to the birthday paradox, where in a group of people, there’s a high probability that two individuals will share the same birthday. The attack does not rely on the strength or weakness of the hash function itself, but on the statistical likelihood of these collisions occurring, which is surprisingly high even for large sets of possible hash values.

References: The explanation is based on the principles of cryptographic hash functions and the birthday problem as described in standard cryptography literature and resources123.

Keeping USB ports enabled on a laptop when not necessary increases the physical attack surface. This is because USB ports can be used to connect devices that may be malicious or compromised, such as USB drives containing malware or tools designed to exploit vulnerabilities in the system’s hardware or software. By leaving USB ports enabled, an attacker with physical access to the laptop could potentially use these ports to launch an attack, bypass security measures, or steal data.

References: The concept of physical attack surfaces includes all the physical means through which an attacker can gain unauthorized access to a system or network. This aligns with the cybersecurity best practices that recommend disabling unnecessary ports and services to minimize the attack surface, as detailed in various security frameworks and guidelines, including those from the EC-Council’s Certified Network Defender (CND) program123.

Syslog and SNMP (Simple Network Management Protocol) are protocols used for different purposes in network management and monitoring. Syslog is primarily a standard for message logging, used to collect system event information from various systems and devices, and it typically sends log data to a centralized Syslog server. SNMP, on the other hand, is used to manage and monitor network devices, and it can send alerts or ‘traps’ to a management station. Both Syslog and SNMP are considered push-based protocols because the information is generally sent (or ‘pushed’) from the devices to the server or management station without the server requesting (or ‘pulling’) the data1234.

References: The information provided here is based on standard network management practices and the functionalities of Syslog and SNMP as outlined in network management and monitoring literature. For more detailed information, please refer to the official Certified Network Defender (CND) study materials and documents provided by the EC-Council.

An incremental backup is a type of data backup that copies only the files that have been created or modified since the last backup operation of any type. This method is efficient because it only backs up data that has changed, which can save on storage space and reduce the time needed to complete the backup. In Kelly’s case, since he is backing up only the new or changed files since the last backup, he is using an incremental backup approach.

References: The explanation aligns with the standard backup methodologies where an incremental backup captures only the changes made since the last backup, which can be either a full or another incremental backup1234.

In MacOS, disk encryption is implemented by enabling the FileVault feature. FileVault is a disk encryption program available in Mac operating systems that uses XTS-AES-128 encryption with a 256-bit key to help prevent unauthorized access to information on the startup disk. It’s designed to encrypt the entire drive on your Mac, protecting your data with a password and automatically encrypting everything stored on the Mac. This feature is particularly important for users who handle sensitive information and want to ensure that their data is secure, even if their computer is lost or stolen.

References: The explanation is based on the official Apple Support documentation, which provides detailed guidance on using FileVault for disk encryption on MacOS12.

Storage Area Network (SAN), which is a dedicated high-speed network that connects servers to storage devices, allowing for the sharing of storage resources. A SAN is designed to handle large amounts of data and provides a way to centralize storage management, making it an efficient solution for enterprises that require reliable and scalable storage infrastructure. It separates the storage units from the servers and the user network, which aligns with the scenario described for Timothy’s organization.

References: The concept of a SAN as a dedicated network for sharing storage resources is well-documented and aligns with industry standards and practices1234.

In a tree network, each node is connected in a hierarchical manner, with the root node at the top. If a main node (such as N1 or N2) fails, all the child nodes connected to it (N11, N12 for N1 and N21, N22 for N2) will be affected because the tree structure relies on the connectivity of the parent node to its children. The failure of a main node will disrupt the transmission path from the root to the child nodes, leading to a loss of connectivity for those child nodes. This is consistent with the principles of network resilience and fault tolerance as outlined in the EC-Council’s Certified Network Defender (CND) program, which emphasizes the importance of each node in maintaining the network’s overall integrity.

References: The explanation is based on the standard network topologies and fault tolerance principles covered in the EC-Council’s Certified Network Defender (CND) curriculum.

Having a web server within the internal network can pose a threat to network security because it increases the attack surface that an adversary can exploit. If not properly secured, internal web servers can be vulnerable to various attacks, such as SQL injection, cross-site scripting, and others. These vulnerabilities can lead to unauthorized access, data breaches, and other security incidents. Therefore, it is crucial to ensure that web servers are securely configured and isolated from the internal network to minimize the risk.

References: The EC-Council’s Certified Network Defender (CND) program discusses the importance of understanding the attack surface and the potential threats associated with having critical services like web servers within the internal network. The program emphasizes the need for strategic placement of network resources and the implementation of robust security measures to protect against internal and external threats1

RAID level 5 is a robust storage solution that provides fault tolerance and improved read performance. It requires a minimum of three drives to function. This setup allows for data and parity information to be striped across all drives in the array. If one drive fails, the system can use the parity information to reconstruct the lost data, ensuring no data loss occurs. This level of RAID is beneficial for systems where data availability and security are critical, without sacrificing too much storage capacity for parity.

References: The minimum number of drives required for RAID level 5 is confirmed by various authoritative sources on RAID technology and storage solutions1234.
