SIEM automated responses: The actions automatically triggered by a Security Information and Event Management (SIEM) system in response to detected events or conditions that meet predefined criteria. These responses could include notifications, system alterations, or other actions intended to mitigate a potential threat. For example, if the SIEM system detects a sudden surge in network traffic that could indicate a denial-of-service attack, it could automatically limit traffic from the suspicious source or alert the security team.
