Attribute-based access control (ABAC) is an authorization strategy that defines access levels based on attributes associated with security principals, resources, requests, and the environment. Azure ABAC builds on role-based access control (RBAC) by adding conditions to Azure role assignments in the existing identity and access management (IAM) system. This preview includes support for role assignment conditions on Blobs and ADLS Gen2, and enables you to author conditions based on resource and request attributes.
Role-assignment conditions enable finer-grained access control for storage resources. They can also be used to simplify hundreds of role assignments for a storage resource. The preview enables you to author conditions for storage DataActions, and can be used with built-in or custom roles.
