Machine Learning functionality is available
throughout the SIEM app. You can view the details of detected anomalies within
Anomalies table widget shown on the Hosts, Network and associated Details
pages, or even narrow to the specific date range of an anomaly from the
Anomaly Score details in the overview of the Host and IP Details pages. Each
of these interfaces also offer the ability to drag and drop details of the

The SIEM app comes with prebuilt machine learning anomaly detection jobs for automatically detecting
host and network anomalies. The jobs are displayed in the
interface. They are available when:
You ship data using Beats, and
Kibana is configured with the required index patterns
winlogbeat-*via Kibana → Management → Index Patterns).
- Your shipped data is ECS-compliant, and Kibana is configured with the data’s index patterns.
Machine learning jobs look back and analyse two weeks of historical data prior to the time they are enabled. After jobs are enabled, they continuously analyse incoming data. When jobs are stopped and restarted within the two week timeframe, previously analysed data is not processed again.
Prebuilt job reference describes all available machine learning jobs and lists which beats are required on your hosts for each job. For information on tuning anomaly results to reduce the number of false positive, see Optimizing anomaly results.
