Not a Fundamental Component of an Intrusion Detection System Alarm

D.

Response is the correct choice.

A response would essentially be the action that is taken once an alarm has been produced by an IDS, but is not a fundamental component of the alarm.

The following are incorrect answers: Communications is the component of an alarm that delivers alerts through a variety of channels such as email, pagers, instant messages and so on.

An Enunciator is the component of an alarm that uses business logic to compose the content and format of an alert and determine the recipients of that alert.

A sensor is a fundamental component of IDS alarms.

A sensor detects an event and produces an appropriate notification.

An intrusion detection system (IDS) is designed to detect unauthorized access to a computer system or network. One important aspect of an IDS is the alarm that is triggered when an intrusion is detected.

The four fundamental components of an alarm in an IDS are:

A. Communications: This component involves the communication channels that are used to alert security personnel of an intrusion. Communications may include email, phone, or text messages.

B. Enunciator: This component is responsible for making the alarm audible or visible. An enunciator may be a speaker, a siren, or a flashing light.

C. Sensor: This component detects the intrusion and sends a signal to the alarm system. Sensors can be physical devices like motion detectors, or software-based like network traffic analyzers.

D. Response: This component specifies the actions that should be taken in response to the intrusion. This may include alerting security personnel, shutting down the system, or activating additional security measures.

Therefore, based on the above explanation, the correct answer to the question is D. Response, as it is a fundamental component of an alarm in an IDS.
