Configure the Tenable Connector

Tenable Connector is the API connector between your ServiceNow instance and Tenable.io/Tenable.sc. As the Tenable platforms receive new API requests, the requests are added to the connector for the other apps to use.

Note: You must be logged in with a ServiceNow account that has the x_tsirm_tio_cmdb.admin role to perform the setup process.

Note: The ServiceNow configuration only supports Tenable.sc versions 5.7 and later.

Before you begin:

You must have a minimum role requirement of Security Analyst in Tenable.sc.

To configure the Tenable connector for Tenable.io/Tenable.sc:

  1. Log in to ServiceNow.
  2. Navigate to Tenable for Connector > Connectors.

  3. Delete any default connectors.

    Note: Tenable does not recommend using the default connector because it uses predefined ServiceNow sysids that can be overwritten during the upgrade process.

  4. In the upper-right corner of the page, from the application picker drop-down box, select Global. For more information, see ServiceNow Scoped Application.
  5. Click New.
  6. Do one of the following:
  7. In the General Settings section, you can specify your Max ECC Wait Time (in seconds) and Request Timeout (in seconds) for each of your configured connectors.
  1. In the Asset Settings section, you can set the Asset Logging Level, Asset Max Cumulative Log Entries, and Asset Max Cumulative Log Sizes. The default setting for the logging levels is Errors Only.
  2. In the Additional Asset Settings section, you can select CI Classes to Ignore. Options are also available to set New Record Sync Frequency (in minutes), Record Update Sync Frequency (in minutes), Asset Max Job Log (in days), and Asset Max Job Wait (in days).

Note: You may have additional settings options on your connector page depending on the Tenable applications you have installed, i.e., Tenable VR (VR Settings), Tenable ITSM (ITSM Settings) , and Tenable Assets (Assets Settings).

Note: For additional information about ServiceNow settings, see the ServiceNow documentation.
