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?
正解：C
解説：
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.
Option A refers to automated technical notifications. Option C focuses on internal analysis discussions.
Option D relates to operational containment communications during malware handling.
Therefore, the scenario emphasizes structured external communication intended for non-organizational entities.

Stanley works as an incident responder at a top MNC based in Singapore. He was asked to investigate a cybersecurity incident that recently occurred in the company. While investigating the incident, he collected evidence from the victim systems. He must present this evidence in a clear and comprehensible manner to the members of a jury so that the evidence clarifies the facts and further helps in obtaining an expert opinion on the incident to confirm the investigation process. In the above scenario, which of the following characteristics of the digital evidence did Stanley attempt to preserve?
正解：A
解説：
In the scenario described, Stanley's effort to present evidence in a clear and comprehensible manner to the members of a jury, with the intention of clarifying facts and aiding in obtaining expert opinion, aligns with the characteristic of admissibility. The admissibility of digital evidence pertains to its acceptability in a court of law, which hinges on the evidence being collected, handled, and presented in a manner that complies with legal standards and procedures. This includes ensuring the evidence is relevant, reliable, and not overly prejudicial. By preparing to present the evidence in a way that the jury can understand and use to confirm the investigation process, Stanley is focusing on ensuring that the evidence meets the criteria for admissibility in the legal proceedings. Completeness, believability, and authenticity are also important characteristics of digital evidence, but the context provided indicates that Stanley's primary focus is on meeting the legal requirements for the evidence to be considered valid in court.

質問 # 223
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：A
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.
