212-89 Exam Dumps - ECCouncil ECIH Questions and Answers

As of my last update, the most recent NIST standard for incident response was NIST Special Publication 800-61 Revision 2 (800-61r2), titled "Computer Security Incident Handling Guide." This document provides guidelines for establishing an effective incident response program, including preparation, detection and analysis, containment, eradication, recovery, and post-incident activity.

References:The document is a key resource in the field of incident response, frequently cited in the ECIH v3 curriculum for its comprehensive guidelines on managing and responding to cybersecurity incidents.

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.References: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.

A Trojan, short for Trojan horse, is a type of malicious software that misleads users of its true intent. It disguises itself as a legitimate and useful program, but once executed, it allows unauthorized access to the user's system. Unlike viruses and worms, Trojans do not replicate themselves but can be just as destructive. They are often used to create a backdoor to a computer system, allowing an attacker to gain access to the system or to deliver other malware. Trojans can be used for a variety of purposes, including stealing information, downloading or uploading files, monitoring the user's screen and keyboard, and more. The term "Trojan" comes from the Greek story of the wooden horse that was used to sneak soldiers into the city of Troy, which is analogous to the deceptive nature of this type of malware in cyber security.

References:The EC-Council's Certified Incident Handler (ECIH v3) program covers various types of malware, including Trojans, in detail, explaining their mechanisms, how they can be identified, and the steps to take in response to such threats.

The correct flow of stages in an Incident Handling and Response (IH&R) process as outlined in the Incident Handler (ECIH v3) by EC-Council begins with Preparation. This phase involves getting ready for potential incidents by developing plans, policies, and procedures, and ensuring that tools and team training are up to date. Incident Recording is the next stage, where incidents are documented and reported. Incident Triage follows, prioritizing incidents based on their impact and urgency. Containment is next, aiming to limit the damage of the incident and prevent further spread. Eradication comes after containment, where the root cause of the incident is removed. Recovery is the stage where affected systems are restored to their operational status. Post-Incident Activities conclude the process, reviewing and learning from the incident to improve future response efforts.

References:This structured approach is foundational in the ECIH v3 program, ensuring that incident handlers are prepared to systematically address and manage cybersecurity incidents efficiently.

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.

References:The ECIH v3 curriculum by EC-Council includes discussions on various methods of conducting vulnerability assessments, highlighting the differences between active and passive techniques, as well as the contexts in which each is most appropriately used.

Cross-site request forgery (CSRF or XSRF) is an attack that tricks the victim's browser into executing unauthorized actions on a website where they are currently authenticated. In this scenario, the attacker exploits the trust that a site has in the user's browser, effectively forcing the browser to perform actions without the user's knowledge or consent. For example, if the user is logged into their bank's website, an attacker could craft a malicious request to transfer funds without the user's direct interaction. CSRF attacks rely on authenticated sessions and typically target state-changing requests to compromise user or application data.

References:The Certified Incident Handler (ECIH v3) curriculum by EC-Council discusses various web-based attacks, including CSRF, detailing their mechanisms, implications, and preventive measures to safeguard against such threats.

Process memory (RAM) is a type of digital evidence that is temporarily stored and requires a constant power supply to retain information. If the power supply is interrupted, the information stored in process memory is lost. This type of evidence can include data about running programs, user actions, system events, and more, making it crucial for forensic analysis, especially in identifying actions taken by both users and malware. Collecting data from process memory helps incident responders understand the state of the system at the time of an incident and can reveal valuable information that is not persisted elsewhere on the device.

References:Incident handling and response training, such as the ECIH v3 program, emphasize the importance of collecting and analyzing volatile data, including process memory, to effectively investigate and respond to cybersecurity incidents.

In Wireshark, to identify ICMP ping sweep attempts, the filtericmp.type == 8 or icmp.type ==0is used. This filter captures ICMP echo requests and echo replies, which are indicative of ping commands. Type 8 represents an echo request used when a source sends a ping, and type 0 represents an echo reply, which is the response from the target. By filtering for these ICMP types, Miko can detect a surge in ping requests across the network, which could indicate a ping sweep attempt—an exploratory activity often used by attackers to discover active hosts on a network by sending ping requests to multiple addresses.References:Incident Handler (ECIH v3) courses and study guides often incorporate training on using network analysis tools like Wireshark, including how to use filters to detect specific types of network activities and potential threats.

The regular expression/exec(\s|\+)+(s|x)p\w+/ixis designed to match patterns that resemble SQL injection attempts, specifically targeting MS SQL Server. This expression looks for the use of theexeccommand followed by one or more spaces or plus signs, and then patterns that start withsporxp, which are prefixes commonly used in SQL Server stored procedures and extended stored procedures. These are often targeted in SQL injection attacks to execute malicious SQL statements. The regular expression provided is a tool used by incident responders like Tibson to identify and analyze potential SQL injection attempts by looking for suspicious patterns in SQL queries.

Shally has incorporated the Defense-in-depth strategy into the incident response plan for Texas Pvt. Ltd. Defense-in-depth is a layered security approach that involves implementing multiple security measures and controls throughout an information system. This strategy is designed to provide several defensive barriers to protect against threats and attacks, ensuring that if one layer is compromised, others still provide protection. The goal is to create a multi-faceted defense that addresses potential vulnerabilities in various areas, including physical security, network security, application security, and user education.References:The Incident Handler (ECIH v3) courses and study guides often emphasize the importance of a Defense-in-depth strategy in creating robust security infrastructures to protect against a wide range of cyber threats.
