The SIEM app in Kibana provides an interactive workspace for security teams to triage events and perform initial investigations. It enables analysis of host-related and network-related security events as part of alert investigations or interactive threat hunting.
Kibana provides step-by-step instructions to help you add data. The SIEM Guide is a good source for more detailed information and instructions.
The default index patterns for SIEM events are
packetbeat-*`. You can change the default index patterns in
Kibana > Management > Advanced Settings > siem:defaultIndex.
The Elastic Endpoint Sensor Management Platform (SMP) ships host and network events directly to the SIEM application, and is fully ECS compliant.
The Elastic Common Schema (ECS) defines a common set of fields to be used for storing event data in Elasticsearch. ECS helps users normalize their event data to better analyze, visualize, and correlate the data represented in their events.
SIEM can ingest and normalize events from ECS-compatible data sources.
