212-89 Exam Dumps - ECCouncil ECIH Questions and Answers

The GPG18 and Forensic readiness planning (SPF) principles outline various guidelines to enhance an organization ' s readiness for forensic investigation and response. Principle 5, which suggests that organizations should adopt a scenario-based Forensic Readiness Planning approach that learns from experience gained within the business, emphasizes the importance of being prepared for a wide range of potential incidents by leveraging lessons learned from past experiences. This approach helps in continuously improving forensic readiness and response capabilities by adapting to the evolving threat landscape and organizational changes.

The EC-Council Incident Handler (ECIH) curriculum stresses the importance of maintaining evidence integrity during recovery operations. Documenting the chain of custody ensures that evidence remains admissible in legal proceedings and maintains forensic validity.

Chain of custody documentation tracks who handled the evidence, when it was accessed, how it was stored, and what actions were performed. This aligns directly with forensic compliance principles, which require proper evidence preservation, documentation, and controlled handling procedures.

While restoring systems, responders must ensure that backup media and affected systems are handled in a way that does not compromise evidence. ECIH emphasizes that recovery should not destroy or contaminate forensic artifacts that may be required for legal, regulatory, or disciplinary action.

Option B (Network segmentation) relates to containment strategies. Option C (Immutable infrastructure) refers to architectural resilience models. Option D (Enhanced authentication) concerns access control, not evidence handling.

Therefore, Logan is adhering to forensic compliance principles during recovery.

Stored XSS occurs when attacker-controlled input is saved by an application and later rendered in other users ' browsers as executable script. Because the scenario explicitly identifies missing output encoding as the weakness, the primary remediation is context-appropriate output encoding before displaying untrusted content. ECIH v3 web-application incident handling emphasizes correcting the underlying application vulnerability rather than relying only on perimeter controls. Proper encoding causes characters with executable significance to be rendered as data instead of browser-interpreted markup or JavaScript. Multi-factor authentication protects accounts but does not prevent XSS. Updating the CMS and plugins is good security hygiene but will not correct custom output-handling flaws. A WAF can provide supplementary detection or blocking, but it should not replace secure application coding. Therefore, proper output encoding directly addresses the root cause.

Advanced persistent threats require coordinated, intelligence-driven response. ECIH emphasizes that APT investigations generate massive volumes of telemetry across endpoints, networks, and cloud platforms.

Option D is correct because Incident Response Automation and Orchestration (IRAO) tools correlate disparate data sources, automate enrichment, and accelerate threat hunting. This enables responders to identify hidden persistence mechanisms and attacker TTPs efficiently.

Options A, B, and C are important but not immediate investigative actions.

ECIH explicitly recommends orchestration platforms for complex, multi-vector incidents such as APTs.

The EC-Council Incident Handler (ECIH) curriculum defines Post-Incident Activity as the phase focused on lessons learned, root cause analysis, and process improvement. Conducting a formal retrospective with cross-functional stakeholders to reconstruct timelines, evaluate decision-making, and identify coordination gaps aligns directly with a structured postmortem analysis.

ECIH emphasizes that post-incident reviews should promote a no-blame culture to encourage transparency and honest feedback. The objective is continuous improvement of incident response playbooks, communication protocols, escalation procedures, and overall organizational readiness. Root cause analysis (RCA) is a key component, ensuring that both technical and procedural weaknesses are identified and corrected.

Option B (reclassification) is an administrative adjustment, not a comprehensive review. Option C (vendor notification) relates to external communication. Option D (checklist updates) may result from the review but does not describe the primary activity being executed.

Therefore, the organization is performing a formal postmortem to analyze root causes and operational effectiveness.

This scenario highlights a preparation phase improvement. ECIH strongly emphasizes the importance of out-of-band communication during incidents, especially when primary systems are compromised.

Option D is correct because VOIP and SMS reporting channels allow incident reporting even when email systems are unavailable or under attack. ECIH identifies out-of-band communication as critical for maintaining coordination and timely escalation during incidents.

Options A–C do not address the reporting failure described.

Establishing alternate communication channels strengthens incident readiness and response resilience, aligning directly with ECIH best practices.

According to the EC-Council Incident Handler (ECIH) curriculum, the first responder’s primary responsibility upon discovering a potential cybercrime is to preserve and protect the crime scene. This includes isolating affected systems, preventing further network communication, restricting physical and logical access, and ensuring no evidence is altered or destroyed.

Sophia’s actions—isolating the system, restricting access, preventing tampering, and escalating to the IR team—align precisely with crime scene protection principles. ECIH emphasizes that improper handling during the early stages of an incident can contaminate evidence and compromise forensic investigations.

Option A (chain of custody documentation) occurs once evidence is formally collected. Option B (evidence log collection) is part of forensic acquisition. Option C (advanced forensic analysis) is performed by specialized investigators later in the response lifecycle.

Therefore, Sophia is performing the role of protecting the integrity of the crime scene as a first responder.

In the ECIH email incident response framework, eradication extends beyond internal cleanup and includes threat intelligence sharing. Option B is correct because sharing phishing indicators with trusted security communities helps disrupt attacker infrastructure and prevents reuse of the same campaign against other organizations.

Option A is unrelated. Option C is ineffective against phishing. Option D is overly destructive and unnecessary.

ECIH promotes collaborative defense as part of post-detection eradication and prevention.

The ECIH Endpoint Security module identifies EDR systems as the cornerstone of modern endpoint incident response. Advanced attacks targeting intellectual property often bypass traditional antivirus controls.

Option C is correct because EDR provides continuous monitoring, behavioral detection, rapid containment, and automated response across endpoints. This capability is critical during high-risk periods such as product launches.

Options A, B, and D are important but insufficient alone for real-time detection and response.

Therefore, deploying a robust EDR system is essential.

Unauthorized access to cloud backend services should immediately trigger examination of identity and access controls because excessive or improperly assigned permissions are a common source of cloud compromise. Reviewing IAM roles allows the responder to determine which principals can access the backend, identify over-privileged or compromised identities, revoke unnecessary privileges, and enforce least privilege. Security Command Center improves ongoing detection but does not directly correct the permissions enabling current unauthorized access. VPC Service Controls can provide an additional service perimeter but should complement rather than replace correct IAM authorization. Migrating the application to another project is disruptive and could reproduce the same access-control weakness if the underlying configuration is not fixed. ECIH cloud incident handling emphasizes addressing the compromised access path and reducing unauthorized privileges before implementing broader defensive improvements.
