What is the primary function of a passive response in intrusion detection?

The primary function of a passive response in intrusion detection systems is to report and record detected problems while relying on human intervention for further action. This approach focuses on monitoring network traffic and system activities to identify potential threats without taking immediate countermeasures.

By documenting the incidents, a passive response allows security analysts to review and analyze the data later, enabling a deeper understanding of the security landscape and potentially informing future defenses. This method is especially useful in environments where preserving data for forensic analysis is crucial, as it minimizes the risk of disrupting operations by avoiding automated drastic actions that could lead to data loss or service interruption.

Passive responses are fundamental in incident response strategies, where the insights gained from recorded events can drive decisions on how best to address vulnerabilities and improve overall security posture.
