Homeland Security

The following projects have been developed under the Department of Homeland Security:



VIAssist is a visual analysis platform to help network security analysts protect their networks. It provides visual tools for theevaluation of network flow and security data. VIAssist presents multiple, coordinated views – highlighted or filtered data in one view is reflected in all other views – to provide different visual perspectives of the data. These views transform network data into a collection of interactive visualizations that make it easier to analyze data, to see patterns and trends, and to identify risks and actionable information.



Critical infrastructures can be vulnerable to cyber attacks through 802.11 wireless networks. WildCAT is a prototype system that enables integration of physical and cyber security resources in order to detect and immediately respond to wireless threats. It is designed to use physical security vehicles as a platform to collect wireless activity and send the data via a cellular network to an analysis center.



MeerCAT is a visualization tool developed to help network defenders and decision makers locate wireless assets and networks (WiFi, 802.11 protocols), and assess the risks to their organization from unauthorized wireless devices. It is designed for post-hoc analysis of data acquired from a variety of sources that discover and locate wireless transmitters.   MeerCAT integrates this data with a geographic information system (GIS) to provide a unified view of detected wireless devices, their vulnerabilities and threats.

Code Dx

Secure Decisions’ Software Assurance Visual Analysis Tool visualizes and correlates weaknesses in software. It increases coverage and confidence in the results of multiple tools; facilitates vulnerability prioritization based on code context; provides developer traceability and trends analysis for process improvement; and integrates with the Software Development Life Cycle (SDLC) for quick and effective remediation.
