Question

Difficulty: MediumInformation Technology and Cybersecurity

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.

Step-by-Step Solution

1
Identify the operational definitions of IDS and IPS in cybersecurity.
IDS focuses on passive observation and alerting, whereas IPS focuses on active inline intervention and packet blocking.
Understanding the fundamental operational mechanism of network security devices is necessary to evaluate the assertion.
2
Compare the defined mechanisms with the given statement.
The statement attributes active packet dropping to IDS and passive monitoring to IPS, reversing their actual technical capabilities.
Identifying functional inversions reveals whether a technical statement regarding network defense is accurate.
