Detection can perform real-time detection and alerting using which of the following?

Real-time detection and alerting in Tanium are enabled by the use of signals. Signals represent a continuous flow of data that can be monitored for changes or patterns indicative of security events or system behaviors that require attention. By leveraging signals, Tanium can analyze incoming data in real-time, enabling quick responses to potential threats or anomalies within the environment.

In this context, policies are generally used for establishing rules and procedures to manage systems, while reputation often pertains to assessing the trustworthiness of endpoints or files based on past behavior or established characteristics. Streams could refer more to data processing mechanisms or workflows but are not specifically associated with real-time detection and alerting. Signals, therefore, provide the immediate feedback loop necessary for effective real-time detection and alerting in Tanium.
