An Infrastructure for Secure Data Sharing: A Clinical Data Implementation

May 15, 2024
Author(s)
Joanna DeFranco, Joshua Roberts, David Ferraiolo, Daniel Compton
Objective: To address database interoperability challenges to improve collaboration among disparate organizations. Materials and Methods: We developed a lightweight system to allow broad but well-controlled data sharing while preserving local data

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

A Trusted Federated System to Share Granular Data Among Disparate Database Resources

March 15, 2021
Author(s)
Joanna DeFranco, David F. Ferraiolo, D. Richard Kuhn, Joshua D. Roberts
Sharing data between different organizations is a challenge primarily due to database management systems (DBMSs) being different types that impose different schemas to represent and retrieve data. In addition, maintaining security and privacy is a concern

Guide to Attribute Based Access Control (ABAC) Definition and Considerations

August 2, 2019
Author(s)
Chung Tong Hu, David F. Ferraiolo, David R. Kuhn, Adam Schnitzer, Kenneth Sandlin, Robert Miller, Karen Scarfone
[Includes updates as of August 2, 2019] This document provides Federal agencies with a definition of attribute based access control (ABAC). ABAC is a logical access control methodology where authorization to perform a set of operations is determined by

Attribute Considerations for Access Control Systems

June 18, 2019
Author(s)
Chung Tong Hu, David F. Ferraiolo, David Kuhn
Attribute-based access control systems rely upon attributes to not only define access control policy rules but also enforce the access control. Attributes need to be established, issued, stored, and managed under an authority. Attributes shared across

Author(s)
Chung Tong Hu, David F. Ferraiolo, Ramaswamy Chandramouli, David R. Kuhn
Until now, ABAC research has been documented in hundreds of research papers, but not consolidated in book form. This book explains ABAC's history and model, related standards, verification and assurance, applications, and deployment challenges; Specialized

Imposing Fine-grain Next Generation Access Control over Database Queries

May 25, 2017
Author(s)
David F. Ferraiolo, Serban I. Gavrila, Gopi Katwala, Joshua D. Roberts
In this paper we describe a system that leverages ANSI/INCITS Next Generation Access Control (NGAC) standard called Next-generation Database Access Control (NDAC) for accessing data in tables, rows, and columns in existing RDBMS products. NDAC imposes
