Eccouncil 212-89 EC-Council Certified Incident Handler v3 Exam Practice Test

Answer : C

WMIC (Windows Management Instrumentation Command-line) is a command-line tool that provides a unified interface for Windows management tasks, including the collection of system information. It allows administrators and forensic investigators to query the live system for information about running services, their process IDs, start modes, states, and statuses, among other data. The use of WMIC is particularly valuable in incident response scenarios for gathering volatile information from a system without having to install additional software, which might alter the state of the system being investigated. By executing specific WMIC commands, Clark can extract detailed information about the services running on a system at the time of the investigation, making it an essential tool for collecting volatile data in a forensically sound manner.

Answer : B

A Denial-of-Service (DoS) attack is characterized by flooding the network with a high volume of traffic to consume all available network resources, preventing intended or authorized users from accessing system, network, or applications. This type of attack aims to overwhelm the target's capacity to handle incoming requests, causing a denial of access to legitimate users. Unlike XSS (Cross-Site Scripting) attacks, URL manipulation, or SQL injection, which exploit vulnerabilities in web applications for unauthorized data access or manipulation, a DoS attack specifically targets the availability of services. Reference: Incident Handler (ECIH v3) courses and study guides cover various types of network security incidents, including Denial-of-Service attacks, detailing their impact on network resources and services.

Answer : B

When Joseph, the IH&R team lead, alerted service providers, developers, and manufacturers about the affected resources, he was engaged in the Containment stage of the Incident Handling and Response (IH&R) process. Containment involves taking steps to limit the spread or impact of an incident and to isolate affected systems to prevent further damage. Alerting relevant stakeholders, including service providers and developers, is part of containment efforts to ensure that the threat does not escalate and that measures are taken to protect unaffected resources. This stage precedes eradication and recovery, focusing on immediate response actions to secure the environment. Reference: The ECIH v3 certification program outlines the IH&R process stages, explaining the roles and actions involved in containment, including communication with external and internal stakeholders to manage and mitigate the incident's effects.

Answer : A

In the described attack, where attackers pose as legitimate access points (APs) by beaconing the WLAN's SSID to lure users, the attack is known as an Evil twin AP attack. This type of attack involves setting up a rogue AP with the same SSID as a legitimate wireless access point, making it appear as an authorized network to users. Unsuspecting users may connect to this malicious AP, allowing attackers to intercept sensitive information, conduct man-in-the-middle attacks, or distribute malware. The Evil twin AP attack exploits the trust users have in known SSIDs to compromise their security. Reference: Incident Handler (ECIH v3) certification materials discuss various confidentiality and network attacks, including Evil twin AP attacks, highlighting their mechanisms and how to defend against them.

Answer : B

Incident response orchestration refers to the process and technologies used to coordinate and streamline the response to security incidents. This approach ensures that incident response teams have clear procedures and workflows to follow, enabling them to act swiftly and effectively when dealing with security incidents. By orchestrating the response, organizations can minimize the impact of incidents, ensure consistent and thorough investigation and remediation activities, and improve their overall security posture. Incident response orchestration involves integrating various security tools, automating response actions where possible, and providing a centralized platform for managing incidents.

Answer : D

A Trojan, or Trojan horse, is a type of malware that disguises itself as a legitimate, harmless program or file to trick users into downloading and installing it. Once activated, a Trojan can perform a range of malicious activities, including giving attackers unauthorized access to the infected system. This can lead to the theft of sensitive information, such as credit card numbers and passwords, and can also allow the attacker to install additional malware, potentially leading to further damage, such as the erasure of data. Unlike viruses and worms, Trojans do not replicate themselves but rely on the deception of users to spread.

Answer : C

Hex encoding (also known as hexadecimal encoding) involves converting binary data into hexadecimal representation. In the context described, when a user submits a request with potentially malicious input (such as a single quote and other characters in an attempt to perform SQL injection), the encoding technique converts this input into a string of hexadecimal digits (ranging from 0 to 9 and A to F). This prevents the direct interpretation of the input as SQL commands by the database, thereby mitigating the risk of SQL injection attacks. This method is a form of input sanitization that helps ensure that user input cannot be used to manipulate database queries directly.
