ECCouncil Updated 212-89 Exam Questions and Answers by ajay

The EC-Council Incident Handler (ECIH) curriculum stresses that periodic access reviews are essential for preventing insider threats. When user roles change or projects end, permissions must be reviewed and adjusted according to the Principle of Least Privilege (PoLP).

In this case, the intern retained access privileges beyond the project duration due to lack of periodic auditing. Regular auditing of user access rights ensures that permissions remain aligned with job responsibilities and reduces the risk of privilege misuse.

Option A (data classification) helps identify sensitive data but does not ensure access rights are revoked. Option B (account lockout policies) addresses brute-force login attempts, not permission creep. Option D (surveillance cameras) concerns physical monitoring.

ECIH emphasizes implementing Role-Based Access Control (RBAC), enforcing least privilege, conducting quarterly or periodic access reviews, and maintaining strong identity governance to mitigate insider threats.

Therefore, regular auditing of user access rights would have prevented this issue.

Lena is performing an active email-containment measure by removing identified phishing messages before the mail server completes their delivery. ECIH v3 emphasizes rapid containment of phishing campaigns once malicious messages, links, senders, or indicators have been validated. Purging queued messages reduces the number of employees exposed to malicious links and therefore decreases the likelihood of additional credential compromise. SIEM correlation can help analyze the foreign login attempts, but it does not prevent pending malicious messages from reaching users. Forensic triage of attachments is inappropriate when the primary attack vector described is a malicious shared-drive link. Isolating individual mailboxes would also fail to address messages queued for broader delivery. Preemptively deleting the identified phishing emails from the mail queue therefore directly contains the campaign and limits its organizational impact.

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.

The incident involves an active cloud-based malware compromise rather than merely an operational scheduling issue. ECIH v3 cloud incident handling emphasizes using cloud-aware security capabilities to identify compromised resources, determine attack scope, detect malicious workloads or processes, and support containment and eradication. Deploying the available cloud security tool directly addresses the active threat and can help identify how the malware is spreading through the cloud environment. Monitoring flight schedules provides operational visibility but does not stop malicious activity. Halting all flights would be a severe business and safety decision that should not be taken without evidence that such disruption is necessary. Passenger notification may eventually be required depending on operational impact but does not remediate the security incident. Therefore, targeted technical investigation and containment using the cloud-specific security tool is the appropriate primary action.
