Which of the following components are usually found in an Intrusion detection system (IDS)? Each correct answer represents a complete solution. Choose two.

The console is the centralized management and display interface of an IDS; it receives alerts generated by sensors, allows administrators to configure detection policies, and presents a unified view of security events across the monitored environment.

A firewall is an independent network security device that enforces traffic filtering rules; while often deployed alongside an IDS, it is not an internal component of the IDS itself.

A modem is a physical signal-conversion device used to connect to a network; it plays no role in the detection, analysis, or management functions of an IDS.

A gateway is a network routing node that connects different networks; it is not a functional building block within IDS architecture.

Sensors are the active detection components of an IDS that monitor network traffic or host activity, compare it against signatures or behavioral baselines, and forward alerts to the console when anomalies or known attack patterns are detected.
