Important Eccouncil 212-89 Exam Questions

Answer: B

Explanation:

This incident indicates credential compromise, a common cloud security issue addressed in the ECIH Cloud Incident Handling module. When credentials are suspected to be compromised, the immediate priority is to stop unauthorized access and determine the scope of misuse.

Option B is correct because resetting the compromised credentials immediately cuts off the attacker's access. Reviewing recent access logs allows responders to validate what actions were taken, which data was accessed, and whether additional accounts were affected. ECIH emphasizes immediate credential revocation as a first-response action in identity-based cloud incidents.

Option D (enabling MFA) is a critical hardening measure but does not immediately revoke compromised credentials. Option A is a recovery step that may not stop ongoing access. Option C may be necessary later but should not delay immediate containment.

Therefore, resetting credentials and reviewing logs is the most effective first action, fully aligned with ECIH guidance.

Answer: C

Explanation:

This question is based on the shared responsibility model, a fundamental concept in ECIH cloud incident handling. While customers manage applications, configurations, and data, the cloud service provider (CSP) controls the underlying infrastructure, including orchestration engines, schedulers, and runtime environments.

System-level telemetry such as hypervisor activity and orchestration logs cannot be accessed by customers. Only the CSP can provide this visibility. Therefore, Option C is correct.

The other options manage higher-level responsibilities but lack authority over infrastructure-layer components.

Answer: B

Explanation:

Email Dossier is a tool designed to assist in the investigation of email incidents by analyzing and validating email headers and providing detailed information about the origin, routing, and authenticity of an email. When Michael is tasked with handling an email incident and needs to check the validity of an email received from an unknown source, Email Dossier can be utilized to trace the email's path, assess its credibility, and identify potential red flags associated with phishing or other malicious email-based attacks.

Answer: A

Explanation:

This scenario highlights violations of forensic readiness and safe malware handling, which are explicitly covered in the ECIH First Response and Malware Analysis modules. ECIH stresses that malware samples must never be handled on production or enterprise-connected systems, as this creates a high risk of accidental execution, lateral infection, and organizational impact.

Option A is correct because ECIH mandates that malicious code samples be stored in isolated, non-networked environments and renamed with non-executable extensions (for example, .malware, .bin, or .txt) to prevent accidental execution. This practice ensures operational safety and preserves forensic integrity.

Option B improves confidentiality but does not prevent accidental execution. Option C supports documentation but does not mitigate execution risk. Option D aids classification but does not address safe handling.

The described behavior---handling live malware on enterprise systems without isolation or renaming---directly contradicts ECIH best practices. Proper sample isolation, renaming, and access restriction are mandatory controls to prevent secondary incidents during investigations, making Option A the correct answer.

Answer: D

Explanation:

ECIH insider threat guidance emphasizes continuous monitoring and behavioral analysis combined with background checks as the most effective deterrent against malicious insiders.

Option D is correct because insider threats often evolve after hiring. Continuous monitoring detects abnormal behavior patterns that static vetting cannot.

Options A--C are insufficient or ineffective against sophisticated insider threats.
