Migrating from DAC to RBAC [PDF]

open access: yes, 2015
Role Based Access Control (RBAC) is one of the most popular means for enforcing access control. One of the main reasons for this is that it is perceived as the least expensive configuration with respect to security administration. In this paper, we demonstrate that security administration is not always cheaper under RBAC when compared to the ...

HBAC: Hierarchical‐Based Access Control Model for Storage Management in Data Lake Environments

open access: yesSoftware: Practice and Experience, Volume 56, Issue 4, Page 445-461, April 2026.
ABSTRACT Background Traditional storage systems typically use simple access control models that manage permissions at the user or group level. These models, however, are not well suited for data lake environments, where large‐scale and diverse datasets must be accessed concurrently by users across multiple hierarchical levels, and they also have many ...

RBAC with ABS - Implementation Practicalities for RBAC Integrity Policies

open access: yesProceedings of the 11th International Conference on Security and Cryptography, 2014
Role-based access control (RBAC) is the de facto access control model used in current information systems. Cryptographic access control (CAC), on the other hand, is an implementation paradigm intended to enforce AC-policies cryptographically. CAC-methods are also attractive in cloud environments due to their distributed and offline nature of operation.
