Edit an ACR Manually

Required License: Tenable.sc+

Required User Role: Organizational user with appropriate permissions. For more information, see User Roles.

You can customize an individual host's Asset Criticality Rating (ACR) value to reflect the unique infrastructure or needs of your organization.

For more information about ACR values, see Asset Criticality Rating in the Tenable.io User Guide.

Tip: If you want to edit the ACR for a host you imported using a remote repository or by connecting a managed Tenable.sc instance to Tenable.sc Director, log in to the Tenable.sc instance that contains the host's data.

Tip: Changes to an ACR value (and recalculations for your ACR values) take effect within 24 hours.

To edit the ACR for a host:

  1. Log in to Tenable.sc via the user interface.

  2. Click Assets > Host Assets.

    The Host Assets page appears.

  3. Click the row for the host.

    The Host Asset Details page appears.

  4. In the Asset Criticality Rating section, click the edit button.

    The Edit Asset Criticality Rating plane appears.

  5. Do one of the following:
    • To modify the ACR value, click the Asset Criticality Rating slider to increase or decrease the ACR.
    • To reset an existing ACR value to the Tenable-provided ACR value, click Reset to Tenable ACR.
  6. (Optional) In the Overwrite Reasoning section, select one or more options to include a justification for your ACR change. For example, if a host in your development lab environment received a Tenable-assigned ACR appropriate for a public host but not the development host, you can select Dev Only.

  7. (Optional) In the Notes box, type a note about your ACR change.
  8. Click Submit.

    Tenable.sc saves the ACR.
