212-89 Exam Dumps - EC Council Certified Incident Handler (ECIH v3)

Comprehensive and Detailed Explanation (ECIH-aligned):

ECIH identifies insider threats as best mitigated through continuous behavioral and activity monitoring, not physical or invasive measures.

Option B is correct because employee monitoring tools can analyze access patterns, file movements, abnormal data transfers, and deviations from normal behavior. These tools provide early warning of malicious insider activity while remaining compliant with legal and privacy frameworks when properly implemented.

Options A, C, and D are ineffective, intrusive, or legally problematic and are explicitly discouraged by ECIH.

Behavioral monitoring allows organizations to detect insider threats proactively rather than reactively, making Option B the most effective control.

Explanation (preparation phase):

This is classic preparation work aimed at improving detection and response speed. Valid incident handling begins before incidents occur: ensuring telemetry exists, logs are collected centrally, alerts are actionable, and roles are defined so handoffs and escalation happen quickly. Reviewing firewall and IDS/IPS logging, centralizing alerts, and aligning the response team on responsibilities directly supports monitoring readiness and operational coordination.

(A) backup hardening is about recovery resilience and integrity of backups; nothing in the scenario references backup configurations or restore testing. (B) law enforcement coordination is a procedural/legal readiness task, not what is described. (C) vulnerability scanning is proactive identification of weaknesses; again, the actions here are about log visibility and alerting, not scanning.

Network monitoring readiness (D) best fits because it includes: ensuring the right data sources are logging, time synchronization, centralized collection (SIEM/log platform), and defined responsibilities for triage and escalation. This aligns with playbook-style preparation models that emphasize roles and monitoring visibility before incidents occur .

In this scenario, the inability to access the file server via Remote Desktop Protocol (RDP), despite the server being pingable and other services functioning normally, suggests a service-specific disruption rather than a complete system shutdown or broader network issue. This pattern is indicative of a denial-of-service (DoS) attack targeted at the file server's RDP service or network congestion that specifically affects RDP connectivity. A DoS attack aims to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet. The fact that other services (like email) are operational rules out broader system or admin account issues, pointing towards a specific problem with accessing the file server, most likely due to a denial-of-service condition.

Viruses are a type of malicious software program designed to infect legitimate software programs. Once a virus is executed, it can corrupt or delete data on a computer, replicate itself, and spread to other files and systems. Unlike worms, which can spread across networks on their own, viruses usually require some form of user interaction, such as opening an infected email attachment or downloading and executing a malicious file, to propagate. Trojans and spyware, while also malicious software, serve different malicious purposes, such as creating backdoors for attackers (Trojans) or spying on users' activities (Spyware).

Comprehensive and Detailed Explanation (ECIH-aligned):

This incident involves adaptive malware embedded within an AI system, actively evolving its behavior. The ECIH malware incident handling methodology prioritizes containment and eradication of the threat before recovery actions. Restoring data without removing the malware risks immediate reinfection and continued manipulation.

Option B is correct because deploying the AI-security module directly targets the malware’s adaptive mechanisms, allowing responders to detect, contain, and eradicate the malicious logic within the AI environment. ECIH emphasizes using appropriate, context-aware security controls that match the technology stack involved in the incident. For AI-driven environments, specialized tools are necessary to counter threats that traditional controls may not detect.

Option A is premature and unsafe prior to eradication. Option C disrupts business operations without resolving the threat. Option D is a communication step that should follow containment and validation.

Therefore, neutralizing the evolved malware using the AI-security module is the correct primary step.

The term "broken account management" refers to vulnerabilities in the account management functions of web applications, which can weaken valid authentication schemes. This can include issues with how accounts are created, updated, managed, and deleted, as well as how users recover forgotten passwords or perform password resets. Poorly implemented account management functions can allow attackers to bypass authentication, elevate privileges, or assume the identity of another user. This weakness is a significant security concern because it directly impacts the ability of a system to safeguard user data and maintain operational integrity.

Comprehensive and Detailed Explanation (ECIH-aligned):

This scenario describes a Remote File Inclusion (RFI) vulnerability. RFI occurs when user-controlled input is used to load external resources into server-side execution contexts. Attackers often use numeric IP addresses and malformed parameters to evade basic filtering.

ECIH identifies RFI as a high-risk web application attack that can lead to malware execution, data leakage, and system compromise. Because the application dynamically loads external content without validation, Option D is correct.

Evidence assessment is a critical step in the investigation phase of the computer forensics process. This step involves evaluating the evidence collected to determine its relevance and significance to the case at hand. It includes analyzing the secured data to identify what information can be used as evidence, its integrity, and how it can be related to the security incident. This phase is pivotal as it helps in building a coherent understanding of the incident and in establishing facts that can be presented in management reports or legal proceedings.
