In network security architecture, an Intrusion Detection System (IDS) is designed to actively block, drop, or alter malicious network packets in real time, whereas an Intrusion Prevention System (IPS) operates purely passively by monitoring network traffic and generating alerts without taking inline defensive actions.
Answer: Answer
Answer
The statement is False. An Intrusion Detection System (IDS) operates passively to monitor network traffic and generate alerts, while an Intrusion Prevention System (IPS) operates inline to actively detect and block malicious traffic.
The statement is False because it reverses the core functional roles of network security monitoring systems. An Intrusion Detection System (IDS) is a passive defense technology that inspects copied network traffic, compares it against known threat signatures or anomalies, and generates log alerts without modifying packet flow. Conversely, an Intrusion Prevention System (IPS) is an active defense tool placed directly inline within the network path to detect threats and immediately block, drop, or reset malicious connections in real time.
