Improved SCADA Visibility and Reporting with PVS 5.2

Note: Passive Vulnerability Scanner (PVS) is now Nessus Network Monitor. To learn more about this application and its latest capabilities, visit the Nessus Network Monitor web page.

At Tenable, our goal is to provide solutions that enable our customers to secure their organizations and improve visibility into their security posture. As part of this commitment, we are pleased to announce the release of Passive Vulnerability Scanner® (PVS™) 5.2, which includes a new SCADA (Supervisory Control And Data Acquisition) analysis module as well as additional enhancements and improvements to provide a deeper understanding of your environment.

Deep visibility into SCADA assets discoverable by PVS

PVS 5.2 includes a new analysis module that analyzes SCADA network traffic to discover SCADA assets and their vulnerabilities. This module provides the same capabilities as SCADA plugins that are used by PVS versions older than 5.2, with an improvement in performance. The module also provides deep visibility into the type of SCADA devices discovered.

We have also added several new SCADA Top-N charts to the dashboard in PVS to provide a high-level summary of SCADA assets, their vulnerabilities, and protocols used by those assets. These include:

  • SCADA Vulnerability Distribution by Severity
  • Top 10 SCADA Hosts
  • SCADA Host Distribution by Protocol
  • SCADA Host Distribution by System Type

Once enabled, these dashboard charts focus directly on SCADA assets to provide a deeper visibility into your SCADA environment:

Improved visibility into network connections

The connection reporting features of the Tenable Network Monitor (TNM) are now available within PVS 5.2 as part of a new Connection Analysis Module. This module eliminates the need for TNM to obtain connection duration and bandwidth information, and extends the platform support to all platforms supported by PVS. Connection duration and bandwidth reporting for IPv6 and tunneled traffic is a new addition and is also available within this module.

Additional enhancements

Other enhancements in PVS 5.2 include improved performance in 10Gbps network traffic analysis, improved support for reporting on hosts within a VLAN, and support for additional versions of OS X.
