ECCouncil Updated 212-89 Exam Questions and Answers by malachi

This scenario involves a high-privilege insider threat, one of the most difficult risks to detect. ECIH emphasizes that senior executives often have broad access, making role-based restrictions impractical.

Option A is correct because advanced employee monitoring and behavioral analytics can detect abnormal access patterns, data exfiltration trends, and deviations from established baselines—even for executives. These tools operate within legal and policy frameworks while providing actionable alerts.

Options B and C reduce efficiency and are easily bypassed. Option D is intrusive and ineffective for digital exfiltration.

ECIH identifies behavioral monitoring as the most effective control for detecting malicious insiders with legitimate access, making Option A correct.

This scenario describes an active malware infection with confirmed command-and-control (C2) communication, which represents an immediate and severe risk to sensitive financial data. According to the EC-Council ECIH malware incident handling process, the first priority in such cases is containment, specifically stopping ongoing malicious activity and preventing further data exfiltration.

Option A is correct because disconnecting the affected servers from the network immediately severs the attacker’s control channel and halts outbound data leakage. ECIH emphasizes that when C2 traffic is observed, responders must act decisively to isolate compromised systems before pursuing deeper forensic analysis or remediation. Containment minimizes damage and reduces legal, financial, and reputational impact.

Option B may preserve system state but allows continued exfiltration until shutdown is complete and may disrupt critical banking operations. Option C is a preventive measure and does not stop an active infection. Option D is valuable for investigation but should occur after containment, not before.

ECIH guidance consistently prioritizes stopping harm over gathering evidence when critical assets are at risk. Therefore, immediate network disconnection of affected servers is the correct triage action.

This scenario exemplifies a classic malicious insider threat, where a trusted employee with legitimate access abuses their privileges. According to the EC-Council ECIH curriculum, traditional perimeter controls and static access restrictions are often ineffective against insiders because the actions appear legitimate at a surface level. Therefore, the primary emphasis must be on behavior-based detection.

Option D is correct because behavioral analytics enables organizations to establish baselines of normal employee behavior and identify deviations such as unusual access times, excessive data downloads, atypical system usage, or abnormal data transfer patterns. ECIH highlights behavioral monitoring as a critical control for detecting insider threats early, especially when access credentials are valid and authorized.

Option A may limit productivity and does not detect malicious intent. Option B is an administrative practice with limited security value. Option C improves awareness but does not detect deliberate malicious behavior.

By implementing behavioral analytics, ClobalTech can identify subtle indicators of insider misuse, respond earlier, and reduce the impact of long-term data exfiltration, aligning with ECIH best practices for insider threat mitigation.
