Achieving cyber survivability in a contested environment using a cyber moving target
Summary
Summary
We describe two components for achieving cyber survivability in a contested environment: an architectural component that provides heterogeneous computing platforms and an assessment technology that complements the architectural component by analyzing the threat space and triggering reorientation based on the evolving threat level. Together, these technologies provide a cyber moving...
Creating a cyber moving target for critical infrastructure applications
Summary
Summary
Despite the significant amount of effort that often goes into securing critical infrastructure assets, many systems remain vulnerable to advanced, targeted cyber attacks. This paper describes the design and implementation of the Trusted Dynamic Logical Heterogeneity System (TALENT), a framework for live-migrating critical infrastructure applications across heterogeneous platforms. TALENT permits...
TALENT: dynamic platform heterogeneity for cyber survivability of mission critical applications
Summary
Summary
Despite the significant amount of effort that often goes into securing mission critical systems, many remain vulnerable to advanced, targeted cyber attacks. In this work, we design and implement TALENT (Trusted dynAmic Logical hEterogeNeity sysTem), a framework to live-migrate mission critical applications across heterogeneous platforms. TALENT enables us to change...
Data diodes in support of trustworthy cyber infrastructure
Summary
Summary
Interconnections between process control networks and enterprise networks has resulted in the proliferation of standard communication protocols in industrial control systems which exposes instrumentation, control systems, and the critical infrastructure components they operate to a variety of cyber attacks. Various standards and technologies have been proposed to protect industrial control...
Range-velocity ambiguity mitigation schemes for the enhanced Terminal Doppler Weather Radar
Summary
Summary
The Terminal Doppler Weather Radar (TDWR) radar data acquisition (RDA) subsystem is being replaced as part of a broader FAA program to improve the supportability of the system. An engineering prototype RDA is under development that will provide a modern, open-systems hardware platform and standards-compliant software. The new platform also...
