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

Once malware is identified, ECIH guidance requires responders to analyze before eradication to understand scope, infection vectors, persistence mechanisms, and data impact. This ensures effective removal and prevents reinfection.

Option C is correct because forensic analysis allows investigators to determine how the malware entered the system, what data was accessed, and whether additional components are compromised. Without this understanding, containment and recovery efforts may be incomplete or ineffective.

Option A is a containment step but does not address root cause. Option B is a notification step that must be supported by verified facts. Option D protects future data but does not address the active malware.

Therefore, forensic analysis is the ideal primary action following detection, as emphasized in the ECIH malware handling process.

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).

Incident triage is the phase in the incident handling and response process where identified security incidents are analyzed, validated, categorized, and prioritized. This step is critical for determining the severity of incidents and deciding on the allocation of resources for effective response. It involves initial analysis to understand the nature of the incident, its impact, and urgency, which guides the subsequent response actions.

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.

Cross-Site Scripting attacks occur when untrusted input is processed and rendered by an application without proper validation or encoding. ECIH web application security guidance identifies input validation and output encoding as the most effective primary defense against XSS.

Option B is correct because sanitizing and validating all user input ensures that malicious scripts are neutralized before being stored or rendered. This addresses the root cause of XSS vulnerabilities.

Option A is a detection control, not a prevention mechanism. Option C improves system security but does not prevent application-level XSS flaws. Option D addresses abuse and DoS scenarios, not script injection.

Therefore, focusing on input validation is the most effective proactive control against XSS, as emphasized in the ECIH curriculum.

Volatile memory contains critical artifacts such as encryption keys, running processes, and network connections. The ECIH Forensic Readiness module emphasizes that volatile evidence must be captured immediately before it is lost.

Option C is correct because capturing memory first preserves irreplaceable evidence, followed by securing the scene to prevent contamination. Powering down systems before memory capture would destroy volatile data.

Options A and D are incomplete without prioritization. Option B is incorrect due to evidence loss.

Thus, immediate memory capture followed by scene security is the correct action.

By classifying and encrypting customer Personally Identifiable Information (PHI), you are specifically guarding against the risk of Sensitive Data Exposure. This OWASP security risk involves the accidental or unlawful exposure of protected data to unauthorized individuals. Encryption serves as a critical defense mechanism by ensuring that, even if data is accessed without authorization, it remains unintelligible and useless to the attacker without the decryption keys. Data classification further supports this by identifying which data is sensitive and requires such protections, ensuring that appropriate security controls are applied to prevent exposure.

MxToolbox is an online tool that provides various network diagnostics and email security checks, including looking up DNS and MX records, SPF records, and more. It can be used by incident handlers to prevent the organization against evolving email threats by analyzing domain health, checking blacklists, verifying email delivery issues, and more. While Email Header Analyzer is useful for analyzing specific emails for traces of phishing or spoofing, G Suite Toolbox might be specific to Google ' s services, and Gpg4win is more focused on email encryption. MxToolbox provides a broader set of functionalities for monitoring and troubleshooting email delivery issues and security threats, making it a versatile tool for incident handlers.
