Granular Access Model
A Granular Access Model is an authorization approach designed to express permissions with a high level of precision.
Definition
A Granular Access Model is an authorization structure in which rights are not granted only in broad packages but can be assigned according to precise actions, target data, context, and time limitations. It is typically used when coarse role assignment is not sufficient to represent the real security and business needs of the organization.
The Ariovis perspective
Roles are useful when they reflect stable business responsibilities and remain governable. Ariovis avoids forcing every exception into the role model and complements roles with controlled requests or contextual authorization.
