Upgrade Notes

If you are running Tenable.sc 5.12.0 or later, you can upgrade directly to Tenable.sc 5.20.0. If you are running a version earlier than Tenable.sc 5.12.0, upgrade to Tenable.sc 5.12.0 before upgrading to Tenable.sc 5.20.0.

If you are using Internet Explorer 11 on Windows 10 LTSB (build 14393.4104), you may need to add your Tenable.sc installation to the “Trusted Sites” zone in order for the application to load.

If you are running Tenable.sc 5.20.0 and you are using pyTenable with the Tenable.sc API, you must upgrade pyTenable to version 1.4.2 or later.

Tenable recommends performing a backup before upgrading Tenable.sc. For more information, see Perform a Backup in the Tenable.sc User Guide.

Note: This release includes a fix for a potential vulnerability. For more information, see the Tenable Product Security Advisory.

Note: If your upgrade path skips versions of Tenable.sc (e.g., upgrading from 5.9.0 to 5.12.0 to 5.20.0), Tenable recommends reviewing the release notes for all skipped versions. You may need to update your configurations because of features and functionality added in skipped versions.

New Features

Asset Host View

Added a Host View table where you can see details about the asset, associated findings (vulnerabilities), and the associated software inventory.

For more information, see View Hosts in the Tenable.sc User Guide.

Asset Criticality Rating (ACR)

Added in automatic calculation of Asset Criticality Rating (ACR) to be used as part of a Risk Based Approach to Vulnerability Management. Automatic ACR calculation can also be overridden to reflect the most accurate picture of each of your Assets criticality to your environment. ACR can be used throughout Tenable.sc. Note this feature requires a Tenable.sc+ license.

Note: As part of the initial ACR score calculation which occurs after the initial Tenable.sc 5.20.0 installation or upgrade, you must re-scan each host to ensure that Tenable.sc has the data required to calculate an ACR score. Until that re-scan has been completed, some hosts may not have an ACR score assigned.

For more information, see View Lumin Metrics in the Tenable.sc User Guide.

Changed Functionality and Performance Enhancements

Display Name in Plugin 19506

Tenable.sc now shows the scan name in Plugin 19506.

Deprecated Shibboleth 1.3

Tenable.sc no longer supports Shibboleth 1.3. Shibboleth 2.0 continues to be supported.

Deprecated Scan Policy Templates

Tenable.sc 5.20.0 no longer supports the following scan policy templates:

  • Badlock detection

  • Bash Shellshock detection

  • DROWN detection

  • Shadow Brokers Scan

You cannot create a new scan policy using a deprecated template using the Tenable.sc UI or API. If you have an existing scan policy using one of these deprecated templates, you can continue to view, edit, and use the templates in scans.

Security Updates
