Adaptive response action history is stored in which index?

The adaptive response action history in Splunk is stored in the "cim_modactions" index. This index specifically captures modifications and actions made in response to security events, which are a critical part of incident response workflows. By storing this information, organizations can trace the actions taken in response to incidents, providing a clear audit trail and enhancing their overall incident response capabilities.

In environments utilizing Splunk, having an organized and dedicated index for adaptive response actions helps in improving data management and retrieval efficiency. It allows administrators and security analysts to easily review the history of responses and their effectiveness within the security operations center (SOC).

The other options do not serve this specific purpose. The "security_events" index is generally used for storing security-related events but is not specifically focused on adaptive response actions. The "response_actions" index might sound relevant, but it does not exist as a standard index in Splunk for this purpose. Finally, the "transaction_index" is typically used for storing transaction-related data and does not pertain to adaptive response action history. Thus, "cim_modactions" is the correct choice for storing adaptive response action history in Splunk.
