Nessus 8.3.0 Release Notes - 2019-03-26

Note: For Nessus 8.3.0 scanners installed on Windows, set the new setting Max Plugin Output Size to 100000 to ensure that scan exports function correctly. You can configure this setting in the Scanning section of Advanced Settings. For more information, see the Knowledge Article Nessus Scanner on version 8.3.0 restarts upon scan completion. This was fixed in version 8.3.1.

New Features

The following are the new features included in the Nessus 8.3.0 Release:

  • Flexibility for Reporting in Nessus Professional - Often there can be too much data; now Nessus enables you to select precisely which information is included when exporting PDF and HTML reports. As an example, a user can choose when exporting to only include the host information, vulnerability information, and vulnerability score when creating a report. The user can also select to save the export options as default for any subsequent exports.
  • Performance updates for Agent deployments using Nessus Manager - Tenable made improvements to the processing time for scan results on Nessus Manager. The update includes disabling the inclusion of Audit Trail and KB data by default. As a best practice, it is recommended leaving these disabled for production environments. For testing/troubleshooting, both abilities can be re-activated for smaller agent groups if needed.
    • Additionally, new options to optimize agent data merge performance can be configured if desired and can provide additional speed-up. See the Agent Advanced Settings documentation for details on configuring these optimizations.

  • Scan Template Updates - Similar to plugin updates, scan templates can be updated at various times. With this release, new policies and policy updates are now delivered automatically.

  • Additional improvements include -

    • Added the ability to update the Offline registration license in the Nessus UI for scanners registered offline.

    • Add a new Advanced Setting plugin_output_max_size_kb, defaulted to 1MB, to configure the maximum per-plugin output size for XML elements in .nessus reports.

    • Added various NASL improvements and bug fixes
