Pass the ECCouncil ECIH 212-89 Questions and answers with CertsForce

In the scenario described, Dickson is performing an active assessment. This type of vulnerability assessment involves using automated tools to actively scan and probe the network for identifying hosts, services, and vulnerabilities. Unlike passive assessments, which rely on monitoring network traffic without direct interaction with the targets, active assessments engage directly with the network infrastructure to discover vulnerabilities, misconfigurations, and other security issues by sending data to systems and analyzing the responses. This approach provides a more immediate and detailed view of the security posture but can also generate detectable traffic that might be noticed by defensive systems or affect the performance of live systems.

In the static data collection process, which is part of digital forensics and incident handling, the focus is on acquiring and examining digital evidence without altering the system or the data itself. This process includes evidence examination, where the data is analyzed; system preservation, where the current state of a system or data is maintained to ensure no alteration occurs; and evidence acquisition, which involves creating an exact binary copy of the digital evidence. Password protection, however, is not a part of the static data collection process. Instead, it relates to securing access to data or systems but does not directly involve the collection or preservation of static data for forensic purposes.

This scenario reflects a suspected cloud workload compromise. The ECIH Cloud Incident Handling module stresses that responders must balance containment, evidence preservation, and service continuity.

Option D is correct because creating snapshots preserves forensic evidence while isolating instances using network ACLs or security groups immediately halts malicious communication. This approach aligns with ECIH guidance to preserve evidence before destructive actions while still containing the threat.

Option B destroys evidence and hinders investigation. Option C alters system state and may trigger attacker countermeasures. Option A delays containment.

ECIH explicitly warns against terminating or rebooting compromised cloud assets before evidence capture. Snapshot-and-isolate is therefore the most effective immediate containment step.

A side channel attack, as described in the scenario, involves an attacker using indirect methods to gather information from a system. In this case, Alice is exploiting the shared physical resources, specifically the processor cache, of a virtual machine host to steal data from another virtual machine on the same host. This type of attack does not directly breach the system through conventional means like breaking encryption but instead takes advantage of the information leaked by the physical implementation of the system, such as timing information, power consumption, electromagnetic leaks, or, as in this case, shared resource utilization, to infer the secret data.

The described attack is a "Watering hole" attack. This type of attack targets specific groups of users by infecting websites they are known to frequently visit. The attacker first identifies websites that are popular with the target group, then finds vulnerabilities in those websites to inject malicious code. When the victims visit the compromised site, the code redirects them to other sites or automatically downloads malware onto their machines. This attack leverages the trust users have in regularly visited sites to distribute malware. Unlike obfuscation application, directory traversal, or cookie/session poisoning attacks, watering hole attacks specifically aim to compromise a commonly used and trusted website to target its users.

In the context of incident handling and response (IH&R), the preparation phase is the initial step where teams and resources are organized to effectively respond to potential security incidents. This phase involves building the IH&R team, developing incident response plans and policies, setting up communication channels, and ensuring that the team has the necessary tools and authority to act. James, being assigned to build an IH&R plan and organize his team, is engaging in the preparation step of the incident response process. This foundational step is crucial for ensuring a coordinated and efficient response to incidents when they occur.

The EC-Council Incident Handler (ECIH) curriculum categorizes incidents such as unauthorized software installation and policy violations under inappropriate usage incidents. In this scenario, the activity originated from a legitimate internal workstation and user account, not an external third party.

The repeated login failures outside business hours combined with installation of an unauthorized remote desktop tool indicate a breach of acceptable use policy and potentially malicious intent. However, the key factor is that the actions were performed by an internal user using valid access credentials, making this an insider-related policy violation rather than an external unauthorized access attack.

Option A implies legitimate remote work within policy boundaries, which is contradicted by the unauthorized software installation. Option B suggests a third-party compromise, but logs indicate activity from an internal user account. Option D (DoS attack) involves service disruption via traffic flooding, which is not described here.

ECIH stresses enforcing acceptable use policies, monitoring user behavior, restricting unauthorized software installation, and applying least privilege controls to mitigate insider misuse. Therefore, this scenario best fits inappropriate usage due to policy violation and unauthorized software installation.

In the context of digital evidence investigation, volatility refers to how quickly data can change or be lost when power is removed or systems are altered. Among the options provided, cache is the most volatile because it is temporary storage that is designed to speed up access to data and is frequently overwritten. Cache data resides in RAM and includes things like memory buffers, system and network information, and process execution data, which are lost upon reboot or power loss. This contrasts with disks, emails, and temp files, which are considered less volatile because they are stored on permanent or semi-permanent media and are less likely to be immediately lost or overwritten.

This scenario focuses on user-driven mitigation of phishing threats, a key element of the ECIH Email Security Incident Handling module. Aarav’s guidance directly reinforces one of the most important user best practices: never engage with suspicious emails.

Option D is correct because avoiding replies or forwarding suspicious emails prevents attackers from validating active accounts, spreading malware, or escalating social engineering attacks. ECIH emphasizes that user interaction often determines the success of phishing campaigns, making awareness and behavior critical controls.

Option A is unrelated to security. Option B is a sender-side control, not a user response. Option C may reduce accidental clicks but does not address the broader behavioral risk.

By instructing users to report, delete, and avoid engagement, Aarav strengthens the organization’s human firewall, which ECIH recognizes as essential in reducing phishing impact.

Racheal should check for DKIM (DomainKeys Identified Mail) in the email headers to analyze the authenticity of received emails. DKIM is an email authentication method designed to detect email spoofing. It provides a way for the receiver to check that an email claimed to have come from a specific domain was indeed authorized by the owner of that domain. It achieves this by affixing a digital signature, linked to a domain name, to each outgoing email message. The recipient can verify this signature to confirm that the email was not altered during its transmission and that it indeed comes from the specified domain, thereby helping to prevent email spoofing. Other options like SNMP (Simple Network Management Protocol), POP (Post Office Protocol), and ARP (Address Resolution Protocol) are not directly related to email authenticity checks.
