Which of the following is NOT a component of an Intrusion Detection System?

In an Intrusion Detection System (IDS), the primary components work together to monitor, detect, and alert on unauthorized access or breaches. Sensors play a critical role by detecting physical changes or movements within a specific area. Control or transmission units facilitate communication and alert signals from the sensors to the central monitoring system. Computerized monitoring systems process and analyze data from those sensors to make informed decisions about security threats.

Manual controls, on the other hand, are not a core component of an IDS. While they can be involved in an overall security strategy (such as manual reporting or checks), they do not constitute an intrinsic part of the system designed for detecting intrusions automatically. The primary purpose of an IDS is to automate the detection process, so relying on manual controls does not align with the system's operational objectives. Thus, identifying manual controls as not a component of an IDS clarifies its essential focus on technology-driven detection and response mechanisms.
