Explanation

An IDS is a passive monitoring system whose primary function is to detect and alert on suspicious or malicious network activity. It analyzes traffic against known attack signatures or behavioral baselines and generates alerts for security personnel to investigate. Critically, an IDS detects but does not prevent attacks-that is the role of an Intrusion Prevention System (IPS), which can actively block malicious traffic (D). An IDS does not remove malware (C) nor is it designed to improve network performance (B).
