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

The ECIH Endpoint Security module stresses that modern endpoint incidents require advanced detection capabilities beyond traditional antivirus or manual inspection. Intellectual property theft often involves stealthy techniques that evade basic controls.

Option C is correct because an Endpoint Detection and Response (EDR) solution provides deep visibility into endpoint behavior, including process execution, memory activity, file changes, and lateral movement. EDR enables analysts to detect, investigate, and validate incidents efficiently across multiple endpoints.

Option B is slow and error-prone. Option A is premature without validation. Option D identifies vulnerabilities, not active compromise.

ECIH highlights EDR as a cornerstone technology for endpoint incident detection and validation, especially in high-value environments such as R&D networks.

The described attack is a "Watering hole" attack. This type of attack targets specific groups of users by infecting websites they are known to frequently visit. The attacker first identifies websites that are popular with the target group, then finds vulnerabilities in those websites to inject malicious code. When the victims visit the compromised site, the code redirects them to other sites or automatically downloads malware onto their machines. This attack leverages the trust users have in regularly visited sites to distribute malware. Unlike obfuscation application, directory traversal, or cookie/session poisoning attacks, watering hole attacks specifically aim to compromise a commonly used and trusted website to target its users.

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.
