EC-COUNCIL EC Council Certified Incident Handler (ECIH v3) 認定 212-89 試験問題 (Q25-Q30):

質問 # 25
Bran is an incident handler who is assessing the network of the organization. He wants to detect ping sweep attempts on the network using Wireshark. Which of the following Wireshark filters would Bran use to accomplish this task?

正解：D

解説：
In the context of using Wireshark, a popular network protocol analyzer, to detect ping sweep attempts on a network, the filter icmp.type==8 is used. ICMP (Internet Control Message Protocol) is utilized for sending error messages and operational information indicating, for example, that a requested service is not available or that a host or router could not be reached. ICMP type 8 messages are echo requests, which are used by the ping command to test the reachability of a host on an IP network. A ping sweep consists of ICMP echo requests sent to multiple hosts to find which ones are alive. By applying the icmp.type==8 filter in Wireshark, Bran can isolate and examine the echo request messages, helping to identify ping sweep attempts, which are characterized by a high volume of ICMP echo requests over a broad range of IP addresses in a short period.


質問 # 26
WebMega, a leading e-commerce giant with over a billion users, suffered a massive data breach, compromising sensitive user data, including financials. During the containment phase, IH&R teams discovered a meticulous attack pattern that bypassed multiple security layers, hinting at an insider's involvement. Investigations revealed that three recently fired employees, with ties to a rival company, had possible motives and means. How should WebMega proceed?

正解：B

解説：
This scenario involves a suspected malicious insider threat with potential external collusion, which significantly elevates legal, regulatory, and evidentiary requirements. The ECIH curriculum emphasizes that when insider activity is suspected-especially involving terminated employees and possible corporate espionage-organizations must prioritize forensic integrity, confidentiality, and lawful investigation.
Option B is correct because collaborating with external forensic experts and law enforcement ensures a neutral, legally defensible investigation. ECIH stresses that insider cases often require specialized forensic capabilities, evidence preservation, and legal authority that internal teams alone may not possess. Maintaining confidentiality protects the organization from reputational damage and legal exposure while facts are being established.
Option A ignores the insider dimension and risks repeat incidents. Option C bypasses legal safeguards and could be interpreted as obstruction or collusion. Option D is premature and exposes the organization to defamation and legal risk without substantiated evidence.
ECIH guidance is clear that complex insider incidents should be escalated appropriately with legal and forensic rigor. Therefore, Option B aligns best with recommended practice.
