Robust access control is a cornerstone of secure software, systems, and networks. An access control mechanism is as effective as the policy it enforces. However, authoring effectiv…
Learning Attribute-Based and Relationship-Based Access Control Policies with Unknown Values
Thang Bui, Scott D. Stoller
Attribute-Based Access Control (ABAC) and Relationship-based access control (ReBAC) provide a high level of expressiveness and flexibility that promote security and information sha…
A Decision Tree Learning Approach for Mining Relationship-Based Access Control Policies
Thang Bui, Scott D. Stoller
Relationship-based access control (ReBAC) provides a high level of expressiveness and flexibility that promotes security and information sharing, by allowing policies to be express…
Algorithm Diversity for Resilient Systems
Scott D. Stoller, Yanhong A. Liu
Diversity can significantly increase the resilience of systems, by reducing the prevalence of shared vulnerabilities and making vulnerabilities harder to exploit. Work on software…
Efficient and Extensible Policy Mining for Relationship-Based Access Control
Thang Bui, Scott D. Stoller, Hieu Le
Relationship-based access control (ReBAC) is a flexible and expressive framework that allows policies to be expressed in terms of chains of relationship between entities as well as…
SLEUTH: Real-time Attack Scenario Reconstruction from COTS Audit Data
Md Nahid Hossain, Sadegh M Milajerdi, Junao Wang +5
We present an approach and system for real-time reconstruction of attack scenarios on an enterprise host. To meet the scalability and real-time needs of the problem, we develop a p…
