Comprehensive and Detailed Explanation (ECIH-aligned):

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.
