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

Software: 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 ...
