SecurityCenter 5.5.1 Release Notes - 7/25/2017

This document describes many of the changes that are included in SecurityCenter 5.5.1, as well as significant enhancements and notes for upgrading. A PDF file of these release notes is also available here.

New Features and Enhancements

Based on customer feedback and Tenable’s own rigorous internal testing process, the latest release of SecurityCenter 5.5.1 includes the following capability improvements:

This point release of SecurityCenter fixes several recently discovered bugs related to Security Content Automation Protocol (SCAP) scans. Previously, when a user attempted to upload a Scap-Oval audit file to SecurityCenter, the application would not display benchmarks and a validation error, "Invalid AuditFile" would be displayed to the user. Now, a SCAP-OVAL audit file can be uploaded (and submitted) with Benchmark Type OVAL Unix or OVAL Windows (by both admin user and org user). Once an SCAP-OVAL audit file is uploaded, it can be viewed, edited, shared, and deleted.

Before You Upgrade

If you are planning an upgrade from SecurityCenter 4.x, due to the many enhancements and changes made in the SecurityCenter 5 solution, Tenable strongly encourages you to install and test the latest version of SecurityCenter in a pre-production environment prior to upgrading in your production environment to ensure the new workflows and enhancements are compatible with your current workflows. To receive an evaluation key that will allow you to install SecurityCenter in a pre-production environment for evaluation, log in to the Tenable Support Portal and click "Activation Codes". Under SecurityCenter, you will see a link to download a demo key for the SecurityCenter 5 solution.
