How many basic communication modes are implemented in intrusion systems?

In intrusion detection systems, the basic communication modes refer to the different ways in which the system can operate and relay information about potential security breaches. The correct number of basic communication modes is four.

These modes typically include passive monitoring, where the system observes and reports without any active interference; active response, where the system takes immediate action upon detection of a threat; report generation, which involves logging events and notifying administrators; and finally, integration with other security systems, which allows for a more centralized approach to security management.

Understanding these four modes is crucial because they define how intrusion detection systems interact with network traffic and respond to incidents, thereby enhancing overall security posture. This knowledge helps in selecting the right system and configuring it effectively to ensure optimal performance in monitoring and responding to security events.
