This rule requires data coming in from Elastic Defend.

|
|
### Elastic Defend Integration Setup
|
|
Elastic Defend is integrated into the Elastic Agent using Fleet. Upon configuration, the integration allows
|
|
the Elastic Agent to monitor events on your host and send data to the Elastic Security app.
|
|
|
|
#### Prerequisite Requirements:
|
|
- Fleet is required for Elastic Defend.
|
|
- To configure Fleet Server refer to the [documentation](https://www.elastic.co/guide/en/fleet/current/fleet-server.html).
|
|
|
|
#### The following steps should be executed in order to add the Elastic Defend integration on a Linux System:
|
|
- Go to the Kibana home page and click "Add integrations".
|
|
- In the query bar, search for "Elastic Defend" and select the integration to see more details about it.
|
|
- Click "Add Elastic Defend".
|
|
- Configure the integration name and optionally add a description.
|
|
- Select the type of environment you want to protect, either "Traditional Endpoints" or "Cloud Workloads".
|
|
- Select a configuration preset. Each preset comes with different default settings for Elastic Agent, you can further customize these later by configuring the Elastic Defend integration policy. [Helper guide](https://www.elastic.co/guide/en/security/current/configure-endpoint-integration-policy.html).
|
|
- We suggest to select "Complete EDR (Endpoint Detection and Response)" as a configuration setting, that provides "All events; all preventions"
|
|
- Enter a name for the agent policy in "New agent policy name". If other agent policies already exist, you can click the "Existing hosts" tab and select an existing policy instead.
|
|
For more details on Elastic Agent configuration settings, refer to the [helper guide](https://www.elastic.co/guide/en/fleet/8.10/agent-policy.html).
|
|
- Click "Save and Continue".
|
|
- To complete the integration, select "Add Elastic Agent to your hosts" and continue to the next section to install the Elastic Agent on your hosts.
|
|
For more details on Elastic Defend refer to the [helper guide](https://www.elastic.co/guide/en/security/current/install-endpoint.html).
