CND 312-38 Exam Questions and Answers PDF

The network security device described is an Intrusion Detection System (IDS). An IDS monitors all inbound and outbound network traffic for suspicious patterns and is configured to alert the network administrator if it detects any such activity. This aligns with the primary function of an IDS, which is to serve as a monitoring system, not necessarily to block traffic like a firewall or act as a decoy like a honeypot. It differs from a proxy server, which would primarily manage and forward web requests on behalf of clients. The IDS operates by analyzing traffic and identifying potential threats based on known signatures or anomalies in network behavior, thereby enabling the network admin to take appropriate action to secure the network12.

References: The explanation provided is based on standard network security practices and the functionalities of an Intrusion Detection System (IDS) as outlined in network security resources. For detailed and specific references, please consult the latest Certified Network Defender (CND) study materials and documents provided by the EC-Council.

Phishing attempts that target users with fake usage bills from a cloud provider are examples of a cloud to user attack surface. This type of attack surface refers to the potential vulnerabilities and entry points that exist between the cloud service provider and the user. In this scenario, the attacker is exploiting the trust relationship between the user and the cloud service provider by presenting a fraudulent bill, hoping the user will reveal sensitive information or make a payment based on the fake bill.

References: The explanation is consistent with the Certified Network Defender (CND) curriculum, which includes understanding various attack surfaces, including cloud and user-related surfaces, and how they can be exploited through phishing and other social engineering attacks12.

 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.

Recovery drill tests are an essential part of disaster recovery planning. They are conducted on backup data to ensure that the data can be successfully restored in the event of a disaster. During these drills, the backup systems are tested to verify that they function correctly and that the data is intact and recoverable. This process helps organizations prepare for actual disaster scenarios and ensures that their backup solutions are effective and reliable.

References: The practice of conducting recovery drill tests on backup data is a standard procedure in disaster recovery and business continuity planning, as outlined in various IT and network security resources123.
