Eccouncil EC-Council Certified Incident Handler v3 212-89 Exam Questions

Answer : B

In the context of information security, the Incident Manager (IM) plays a crucial role in handling incidents from both a management and technical perspective. The Incident Manager is responsible for overseeing the entire incident response process, coordinating with relevant stakeholders, ensuring that incidents are analyzed, contained, and eradicated efficiently, and that recovery processes are initiated promptly. They are pivotal in ensuring communication flows smoothly between technical teams and upper management and that all actions taken are aligned with the organization's broader security policies and objectives. Unlike network administrators, threat researchers, or forensic investigators who may play more specialized roles within the incident response process, the Incident Manager has a broad oversight role that encompasses both technical and managerial aspects to ensure a comprehensive and coordinated response to security incidents.

Answer : A

This scenario describes an evil twin attack, a well-documented wireless network threat covered in the ECIH Network Security Incidents module. An evil twin attack occurs when an attacker sets up a rogue wireless access point that mimics the SSID of a legitimate network. Unsuspecting users connect to the stronger or more accessible signal, allowing attackers to intercept credentials, inject malware, or perform man-in-the-middle attacks.

Option A is correct because the presence of an unauthorized access point broadcasting the same SSID and causing authentication failures is a defining indicator of an evil twin attack. Users may unknowingly connect to the malicious access point, leading to repeated disconnections from the legitimate network.

Option B would not involve a rogue access point. Option C focuses on identity spoofing at the MAC layer but does not explain SSID duplication. Option D involves IP address assignment issues, not SSID impersonation.

ECIH emphasizes that identifying rogue wireless infrastructure quickly is critical to containment. Detecting evil twin attacks allows responders to isolate the rogue device, protect credentials, and restore secure wireless operations.

Answer : C

Omnipeek is a network analyzer tool that allows for the capture and analysis of data packets transmitted across a network. It is designed to provide deep insights into network traffic, enabling users to examine various aspects of the data packets, including network protocols, ports, devices, and potential issues in network transmission. This tool would be ideal for Chandler, who is targeting the Technote organization with the intent of intercepting and analyzing network traffic to obtain sensitive organizational information. Omnipeek's capabilities in packet analysis make it suitable for such activities, offering detailed visibility into the network's operation and data flows.

Answer : B

This incident involves active data exfiltration, which ECIH malware handling guidance identifies as a critical containment priority. When malware is actively transmitting sensitive data, stopping the leak takes precedence over deep analysis.

Option B is correct because using the network traffic analyzer to identify and halt outbound malicious communication immediately prevents further data loss. ECIH stresses that containment actions must first stop harm before eradication and recovery.

Option A supports eradication but does not immediately stop exfiltration. Option C is premature. Option D is unreliable and risks reinfection.

Therefore, halting malicious transmissions is the ideal first step.

Answer : B

Auditing the system and network log files is a crucial step in the incident triage phase of the incident response and handling process. During incident triage, incident handlers assess and prioritize incidents based on their severity, impact, and the urgency of the response required. Part of this assessment involves reviewing log files to understand the nature of the incident, its scope, and the systems or networks affected. This information helps in categorizing the incident and deciding on the appropriate response actions. Unlike containment, which aims to limit the damage, incident disclosure, which involves communicating about the incident, or incident eradication, which focuses on removing the threat, incident triage is about evaluating and prioritizing the incident based on detailed log analysis among other factors.

Answer : D

This scenario is a clear example of a deceptive phishing attack, which is extensively covered in the ECIH Email Security Incident module. Deceptive phishing involves impersonating a trusted internal entity---such as HR---to trick recipients into disclosing sensitive information like credentials or personal data.

Option D is correct because the email impersonates HR, uses social engineering, and directs users to a visually identical but fraudulent login page hosted on an unfamiliar domain. These characteristics are classic indicators of deceptive phishing.

Option A refers to DNS manipulation and is not evidenced here. Option B involves overwhelming email volume rather than deception. Option C refers to unsolicited bulk email without impersonation.

Elena's actions align with ECIH best practices: preserving headers for forensic validation, capturing screenshots to document fraudulent infrastructure, and blocking malicious domains to prevent further exposure. Correctly categorizing the incident as deceptive phishing ensures appropriate eradication, awareness, and reporting measures.

Answer : C

Live data acquisition is the process of collecting volatile data from a system that is still running. Volatile data includes information stored in system memory (RAM), cache, and system and network configuration settings that are lost when the system is powered off. This method is essential for capturing data that can provide insights into the state of the system at the time of an incident, including active network connections, running processes, and the contents of memory. Marley must employ live data acquisition to ensure that this crucial and ephemeral data is not lost, which can be pivotal in understanding and responding to the incident effectively.
