Challenges of Assured Autonomy

February 28, 2024
Author(s)
D. Richard Kuhn
This article summarizes some recent novel approaches to the problem of verification, testing, and assurance of autonomous systems. These include proxy verification and combinatorial methods for input space coverage measurement, which also has applications

Application of the Hybrid Satellite Network Cybersecurity Framework Profile: An Example Implementation of NIST IR 8441

February 23, 2024
Author(s)
Frederick R. Byers, Dan Mamula, Karri Meldorf, Joseph Brule, Rory Jennings, John Wiltberger, Eugene Craft, John Dombrowski, O'Ryan Lattin, Abdul Noor, Matt Yetto, Aliaksander Mamonau, Oksana Slivina, Jay Sharma, Dr. Kangmin Zheng
The space sector is transitioning towards Hybrid Satellite Networks (HSN), an aggregation of independently owned and operated terminals, antennas, satellites, payloads, or other components that comprise a satellite system. The elements of an HSN may have

Human-in-the-loop for Bayesian autonomous materials phase mapping

February 7, 2024
Author(s)
Felix Adams, Austin McDannald, Ichrio Takeuchi, A. Gilad Kusne
Autonomous experimentation achieves user objectives more efficiently than Edisonian studies by combining machine learning and laboratory automation to iteratively select and perform experiments. Integrating knowledge from theory, simulations, literature

Combinatorial testing for building reliable systems

February 5, 2024
Author(s)
M S Raunak, D. Richard Kuhn, Raghu N. Kacker, Yu Lei
Combinatorial testing is an approach where test suites are developed by efficiently covering interactions of parameter values and configuration settings. Multiple studies over the years have shown the interesting phenomenon where almost all defects in a

Use Cases for Secure and Trusted Granular Data Sharing Among Disparate Databases

January 30, 2024
Author(s)
Joanna DeFranco, David Ferraiolo, Joshua Roberts, D. Richard Kuhn
Sharing data among disparate organizations can be extremely difficult, when the data comes from different database management systems (DBMS). Most problematic is that data stored at another organization most likely uses different DBMS schemas and

Employing Word-Embedding for Schema Matching in Standard Lifecycle Management

December 29, 2023
Author(s)
Hakju Oh, Boonserm Kulvatunyou, Albert T. Jones, Tim Finin
Today, businesses rely on numerous information systems to achieve their production goals and improve their global competitiveness. Semantically integrating those systems is essential for businesses to achieve both. To do so, businesses must rely on

Cybersecurity of Genomic Data

December 20, 2023
Author(s)
Ronald Pulivarti, Natalia Martin, Frederick R. Byers, Justin Wagner, Justin Zook, Samantha Maragh, Jennifer McDaniel, Kevin Wilson, Martin Wojtyniak, Brett Kreider, Ann-Marie France, Sallie Edwards, Tommy Morris, Jared Sheldon, Scott Ross, Phillip Whitlow
Genomic data has enabled the rapid growth of the U.S. bioeconomy and is valuable to the individual, industry, and government because it has multiple intrinsic properties that in combination make it different from other types of high value data which

The Design and Application of a Unified Ontology for Cyber Security

December 9, 2023
Author(s)
Ashrafi Akbar, Fariha Rahman, Anoop Singhal, Latifur Khan, Bhavani Thuriasingham
Ontology enables semantic interoperability, making it highly valuable for cyber threat hunting. Community-driven frameworks like MITRE ATT&CK, D3FEND, ENGAGE, CWE and CVE have been developed to combat cyber threats. However, manually navigating these

Automation Support for Control Assessments - Project Update and Vision

December 6, 2023
Author(s)
Eduardo Takamura, Jeremy Licata, Victoria Yan Pillitteri
In 2017, NIST published a methodology for supporting the automation of SP 800-53 control assessments in the form of IR 8011. IR 8011 is a multi-volume series that starts with an overview of the methodology (volume 1) and provides guidance and

Facilitating Stakeholder Communication around AI-Enabled Systems and Business Processes

November 21, 2023
