Setup
editSetup
The rule requires the Lateral Movement Detection integration assets to be installed, as well as file and Windows RDP process events collected by the Elastic Defend integration.
Lateral Movement Detection Setup
The Lateral Movement Detection integration detects lateral movement activity by identifying abnormalities in file and Windows RDP events. Anomalies are detected using Elastic’s Anomaly Detection feature.
Prerequisite Requirements:
- Fleet is required for Lateral Movement Detection.
- To configure Fleet Server refer to the documentation.
- File events collected by the Elastic Defend integration.
- To install Elastic Defend, refer to the documentation.
The following steps should be executed to install assets associated with the Lateral Movement Detection integration:
- Go to the Kibana homepage. Under Management, click Integrations.
- In the query bar, search for Lateral Movement Detection and select the integration to see more details about it.
- Follow the instructions under the Installation section.
- For this rule to work, complete the instructions through Add preconfigured anomaly detection jobs.
