Note: If your upgrade path skips versions of Tenable Security Center (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.
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 Security Center 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 Security Center. Note this feature requires a Tenable Security Center+ license.
Note: As part of the initial ACR score calculation which occurs after the initial Tenable Security Center 5.20.0 installation or upgrade, you must re-scan each host to ensure that Tenable Security Center 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 Security Center User Guide.
