Manage OT Connectors

The following is not supported in Tenable FedRAMP Moderate environments. For more information, see the Tenable FedRAMP Product Offering.

Required User Role: Scan Manager or Administrator

Use the following procedures to manage your Tenable One OT Exposure connectors. For general information about OT connectors, see OT Connectors.

To open the OT Connectors menu in Tenable One Vulnerability Management:

  1. In the left navigation, click Sensors.

    The Sensors page appears. By default, the Nessus Scanners tab is active and Linked Scanners is selected in the drop-down box.

  2. Click the OT Connectors tab.

    The list of linked OT connectors appears.

Add an OT Connector

  1. Click Add OT Connector.

    The Add OT Connector window appears.

  2. Click Generate.

    Tenable One Vulnerability Management shows the appropriate cloud site to link the Tenable One OT Exposure connector to and generates an OT linking key.

    Note: You can use the linking key to link one Tenable connector, and you must use the linking key within two hours of generation. To link additional OT connectors, generate and use a new linking key for each connector.

  3. Use the cloud site and linking key to link the connector to Tenable One Vulnerability Management from the Tenable One OT Exposure user interface. For more information, see the Tenable One OT Exposure User Guide.

Edit an OT Connector Name or Type

To ensure that your OT connectors are recognizable and represent the correct types, you may need to modify the OT connector names and types in Tenable One Vulnerability Management. You can choose from two types: ICP and EM (Enterprise Manager). For more information about the types, see the Tenable One OT Exposure User Guide.

Note: Updating an OT connector name or type in Tenable One Vulnerability Management does not cause any changes in Tenable One OT Exposure.

To edit an OT connector name or type:

  1. In the OT Connectors table, double-click the Name or Type cell to edit it.

  2. Enter the new name or select the new type (ICP or EM).

  3. Click out of the cell.

    Tenable One Vulnerability Management saves your change.

Enable or Disable an OT Connector

There may be some cases where you want to disable an OT connector temporarily and enable it at a later time. For example, you may want to disable an OT connector if Tenable One OT Exposure begins sending data from an unwanted network to Tenable One Vulnerability Management. Once the issue is resolved, you can re-enable the connector.

To enable or disable an OT connector:

  1. In the OT Connectors table, click in the row of the connector that you want to enable or disable.

    A drop-down menu appears.

  2. If the connector is currently enabled, click Disable. If the connector is currently disabled, click Enable.

    If you enabled the connector, Tenable One Vulnerability Management bolds the connector row text and updates the Enabled column to Yes. If you disabled the connector, Tenable One Vulnerability Management grays the connector row text and updates the Enabled column to No.

Delete an OT Connector

Delete an OT connector from Tenable One Vulnerability Management if you no longer want the OT connector to send data to Tenable One Vulnerability Management. For example, if you need to redeploy Tenable One OT Exposure, you would need to delete any connector associated with the old deployment.

Tenable recommends that whenever you delete an OT connector from Tenable One Vulnerability Management, you also delete the related connector in Tenable One OT Exposure to ensure that Tenable One Vulnerability Management and Tenable One OT Exposure stay aligned.

Note: You cannot undo an OT connector deletion; if you want to relink the OT connector, you have to repeat the Add an OT connector process.

To delete an OT connector from Tenable One Vulnerability Management:

  1. In the OT Connectors table, click in the row of the connector that you want to delete.

    A drop-down menu appears.

  2. Click Delete.

    The Delete OT Connector window appears.

  3. Click Delete.

    Tenable One Vulnerability Management removes the connector from the table.
