ESA rule deployments map rules from your rule library to the appropriate ESA Services and data sources. The Deployment panel (CONFIGURE > ESA Rules > Rules tab) enables you to create and configure ESA rule deployments that specify:
- ESA Services
- Data Sources (This is available in NetWitness Platform version 11.3 and later.)
- ESA Rules
When you are ready to start aggregating data and generating alerts from an ESA rule deployment, you deploy the ESA rule deployment to activate it.
Note: An ESA rule deployment can have only one ESA service. You can, however, use the same ESA service in multiple deployments.
In NetWitness Platform version 11.2 and earlier, the ESA service is the Event Stream Analysis service. In version 11.3 and later, it is the ESA Correlation service.

Deployment Panel
The following figure shows the Deployment panel.
ESA Services
In the ESA Services section, you can manage each ESA service in the deployment.
The following table describes the actions you can perform in the ESA Services section.
|
 | Adds an ESA service to the deployment. |
 | Removes the selected ESA service from the deployment. |
The following table describes the columns in the ESA Services section.
| Status | Indicates if the deployment status is Added, Deployed, Updated, or Failed. |
| Name | Name of the ESA service. |
| Address | IP address of the host where the ESA service is installed. |
| Version | Version of the ESA service. |
| Last Deployment Date | The date and time when the ESA service was last deployed. |
Data Sources
Note: This option is available in NetWitness Platform version 11.3 and later.
In the Data Sources section, you can select one or more data sources, such as Concentrators, to use for your selected ESA Service.
The following table describes the actions you can perform in the Data Sources section.
|
| | Adds a data source for the selected ESA service to the deployment. |
| | Removes a data source for the selected ESA service from the deployment. |
The following table describes the columns in the Data Sources section.
| (Status) | Shows the status of the data source. A solid colored green circle indicates a running service and a white circle indicates a stopped service. |
| Name | Shows the name of the data sources used by the selected ESA service. You can specify the data sources separately for each ESA rule deployment. |
| Type | Shows the type of the data sources. Data sources can be Concentrators or Decoders. It is important that you choose data sources that have the appropriate data for the rules in the deployment. For example, if you have NetWitness Endpoint and you want to deploy the Endpoint Risk Scoring Rules Bundle, you must choose endpoint data sources. |
Note: You can add a Log Decoder as a data source for ESA, but it is better to add a Concentrator to take advantage of undivided aggregation as the Decoder may have other processes aggregating from it.
Deployment Options
There are two deployment options below the Data Sources section. These options apply to the entire ESA rule deployment.
The following table describes these deployment options.
|
| Show Updates | Enables you to view a history of updates to the deployment. |
| Deploy Now | Activates the ESA rule deployment. The selected ESA service starts aggregating data and generating alerts using the specified ESA rules in the deployment. You need to add ESA Rules to the deployment before deploying the ESA rule deployment. |
ESA Rules
In the ESA Rules section, you manage rules in the deployment. This section lists all rules that are currently in the deployment.
The following table describes the actions you can perform in the ESA Rules section.
|
| | Opens the Deploy ESA Rules dialog, where you can select a rule. |
| | Removes the selected ESA rules from the deployment. |
 | Filters the list of rules. |
 | Enables you to search for a rule. |
The following table describes the columns in the ESA Rules section.
| Status | Indicates the rule status: - Deployed - the rule is deployed.
- Updated - the rule has been updated since the last deployment.
- Added - the rule has been added since the last deployment.
- Failed - the deployment failed.
|
| Rule Name | Describes the purpose of the ESA rule. |
| Trial Rule | Indicates whether the rule is Deployment mode to see if the rule runs efficiently. |
| Severity | Shows the threat level of alert triggered by the rule. |
| Type | Shows the type of the ESA rule. For more information, see ESA Rule Types. |
| Email, SNMP, Syslog, Script | Indicates which notification types are used for alerts generated by the rules. (ESA SNMP notifications are not supported in NetWitness Platform version 11.3 and later.) |
| Last Modified | Shows the date and time when the ESA rule was last modified. |
