Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the Eccouncil Certified Network Defender exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Eccouncil in their Eccouncil 312-38 exam. These outdated questions lead to customers failing their Eccouncil Certified Network Defender exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Eccouncil 312-38 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
Which of the following indicators are discovered through an attacker's intent, their end goal or purpose, and a series of actions that they must take before being able to successfully launch an attack?
Indicators of attack (IoA) provide information about the attacker's intent, end goals, and the actions they take to execute an attack. IoAs help identify the methods and behaviors an attacker uses during the attack lifecycle. Unlike Indicators of Compromise (IoCs), which are used to detect evidence of a breach, IoAs are proactive and help in identifying and preventing potential attacks before they occur by analyzing the patterns and tactics used by attackers.
Key risk indicators: Metrics used to signal increased risk exposure.
Indicators of compromise: Artifacts observed on a network or in an operating system that with high confidence indicate a computer intrusion.
Indicators of exposure: Data points or signals that reveal vulnerabilities or weaknesses that could be exploited.

Which of the following attack surface increase when you keep USB ports enabled on your laptop unnecessarily?
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.
Which filter to locate unusual ICMP request an Analyst can use in order to detect a ICMP probes
from the attacker to a target OS looking for the response to perform ICMP fingerprinting?
In the context of network security, ICMP fingerprinting is a technique used to determine the operating system of a target machine by analyzing its responses to ICMP requests. The correct filter to detect unusual ICMP requests that could be indicative of ICMP probes from an attacker is option C. This filter looks for ICMP echo requests (type 8) that do not have a corresponding echo reply (code 0). Since the code for an echo request is 0, the filter(!(icmp.code==8))is used to exclude other ICMP messages with different codes.
Malone is finishing up his incident handling plan for IT before giving it to his boss for review. He is outlining the incident response methodology and the steps that are involved. What is the last step he should list?
The last step Malone should list in his incident handling plan is 'A follow-up'. This step is crucial as it involves analyzing the incident to understand how it occurred and what can be done to prevent similar incidents in the future. It often includes a review of the effectiveness of the response, identification of lessons learned, updating policies and procedures accordingly, and conducting training sessions if necessary. This step ensures that the organization improves its security posture and is better prepared for future incidents.
Which of the following Event Correlation Approach checks and compares all the fields systematically and intentionally for positive and negative correlation with each other to determine the correlation across one or
multiple fields?
The Field-Based Approach in event correlation involves systematically checking and comparing all fields for both positive and negative correlations to determine the relationships across one or multiple fields. This approach is methodical and intentional, examining the data within each field and across fields to identify patterns and connections that may indicate security events or incidents.
