最新的 ECIH Certification 212-89 免費考試真題 (Q90-Q95):

問題 #90
Which stage of the incident response and handling process involves auditing the system and network log files?

A. Containment
B. Incident disclosure
C. Incident eradication
D. Incident triage

答案：D

解題說明：
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.

問題 #91
A multinational SaaS provider detects a major security breach involving unauthorized access to customer billing data in its EU and APAC servers. After triage and legal review, the IH&R team confirms data exfiltration impacting regulated regions. In response, the CISO, with legal and compliance teams, initiates a structured communication protocol--informing affected clients, notifying data protection authorities under laws such as GDPR, and preparing media responses with public affairs. All communications are securely routed, reviewed for legal accuracy, and sent only with executive approval to mitigate risk and misinformation. What type of communication is emphasized in this scenario?

A. Technical internal update focused on root cause analysis
B. External communication intended for non-organizational entities
C. Automated alert forwarding using SIEM-generated rules
D. Containment communications shared during malware removal

答案：B

解題說明：
The EC-Council Incident Handler (ECIH) curriculum outlines structured communication protocols as a critical part of incident management, particularly when regulated data and external stakeholders are involved. When data breaches affect customers and fall under regulatory frameworks such as GDPR, organizations are legally required to notify affected individuals and data protection authorities within defined timelines.
The scenario describes communication with clients, regulatory authorities, and media representatives. These stakeholders are external to the organization. ECIH categorizes this as external communication, which must be carefully coordinated with legal, compliance, and executive leadership to ensure accuracy and regulatory compliance.
ECIH emphasizes that external communication must be controlled, legally reviewed, approved by executive leadership, and aligned with regulatory requirements to prevent misinformation and reduce reputational damage. This differs from internal updates or automated alerts.

問題 #92
Alice is an incident handler and she has been informed by her lead that the data on affected systems must be backed up so that it can be retrieved if it is damaged during the incident response process. She was also told that the system backup can also be used for further investigation of the incident. In which of the following stages of the incident handling and response (IH&R) process does Alice need to do a complete backup of the infected system?

A. Containment
B. Incident triage
C. Eradication
D. Incident recording

答案：A

解題說明：
In the incident handling and response (IH&R) process, backing up the data on affected systems is a critical step that usually falls under the Containment phase. The Containment phase is crucial for limiting the scope and severity of an incident, ensuring that it does not spread further or affect additional systems. Backing up affected systems during containment is essential for several reasons: it preserves a snapshot of the system in its current state for forensic analysis, ensures that data is not lost if the system needs to be wiped or altered during the response process, and helps in the recovery process if data is corrupted or lost.
By performing a complete backup of the infected system during the Containment phase, Alice ensures that there is a reliable copy of all data and system states before any major actions, such as eradication or deeper forensic analysis, are taken. This step is also preparatory for the potential use of the backup in analyzing how the incident occurred and in restoring system functionality after the incident is resolved.
References:EC-Council's Certified Incident Handler (ECIH v3) courses and study guides highlight the importance of the Containment phase in the IH&R process, including the practice of backing up affected systems to prevent data loss and to aid in the investigation and recovery processes.

問題 #93
Which of the following digital evidence temporarily stored on a digital device that requires a constant power supply and is deleted if the power supply is interrupted?

A. Process memory
B. Event logs
C. Slack space
D. Swap file

答案：A

解題說明：
Process memory, or volatile memory (RAM), is digital evidence that requires a constant power supply to retain data and is deleted or lost when the power supply is interrupted. It contains information about the system's ongoing processes and operations. This type of evidence can be crucial for forensic investigations as it may hold information about user actions, system events, and the state of applications and services at the time of an incident. Unlike swap files, event logs, and slack space, which can retain information without a constant power supply, process memory is inherently volatile and its contents are lost when a device is powered off or restarts.
References:The ECIH v3 certification program includes discussions on digital forensics and the importance of different types of digital evidence, including volatile and non-volatile memory, in the context of incident response and investigation.

問題 #94
TechStream, a rising tech start-up, developed an AI-powered chatbot for its clients' websites. Shortly after deployment, users reported receiving malicious links and phishing messages from the chatbot. Preliminary investigation traced the issue to an attacker exploiting the chatbot's AI training module. Which of the following steps would be the most efficient in addressing this vulnerability?

A. Limiting the chatbot's ability to share links or external content.
B. Disabling the chatbot until a complete security review is done.
C. Introducing CAPTCHA challenges before users can interact with the chatbot.
D. Implementing strict input validation for any data fed to the chatbot.

答案：D

解題說明：
Comprehensive and Detailed Explanation (ECIH-aligned):
The root cause of this incident is unvalidated input poisoning the AI training process, resulting in malicious output. ECIH web application security principles emphasize that input validation is the primary control against injection and manipulation attacks.
Option B is correct because strict validation ensures that malicious or untrusted data cannot influence training or response generation. This addresses the vulnerability at its source.
Option A adds friction but does not stop poisoning. Option C is disruptive and not efficient. Option D limits functionality without fixing the underlying issue.
ECIH stresses fixing vulnerabilities at the root rather than applying superficial controls, making Option B correct.
