Perform manual packet inspection using a protocol analyzer

Monitor for abnormal surges of repeated ACK responses

Use an Intrusion Detection System (IDS)

Evaluate authentication token generation patterns

CThe correct answer is C. Use an Intrusion Detection System (IDS).The organization needs continuous visibility into network exchanges and detection of activity that deviates from normal behavior. That is the purpose of an Intrusion Detection System.CEH-aligned IDS material explains that an IDS monitors packets on the network and attempts to discover whether an attacker is trying to break into a system or cause a denial-of-service attack . Another CEH reference states that an IDS listens to and monitors network traffic, analyzes packets, searches for intrusion patterns, and alerts administrators when unusual or suspicious traffic is detected . IDS solutions may use signatures and anomaly detection, where anomaly detection identifies behavior that differs from an established baseline .Option A. Manual packet inspection using a protocol analyzer is useful for investigation, but it does not provide scalable ongoing monitoring and alerting.Option B. Monitoring repeated ACK surges is too narrow and would not detect the broader range of abnormal command or session behavior described.Option D. Evaluating authentication token generation patterns is useful for session management testing but does not provide continuous network-wide visibility.Option C. Use an Intrusion Detection System (IDS) is correct because it provides continuous packet monitoring, suspicious behavior detection, and alerting.Therefore, the best answer is C. Use an Intrusion Detection System (IDS).
