Which authorization framework supports both coarse-grained and fine-grained authorization?

The authorization framework that supports bothcoarse-grainedandfine-grainedauthorization isaccess control based on attributes. Attribute-based access control (ABAC) uses attributes (e.g., user roles, resource types, environmental conditions) to define policies that can range from broad (coarse-grained) to highly specific (fine-grained).

Option A: Incorrect. Role-based access control (RBAC) primarily supports coarse-grained authorization and lacks the flexibility for fine-grained control.

Option B: Incorrect. Access control based on lists and roles combines RBAC with access control lists but still lacks the granularity of ABAC.

Option C: Correct. Attribute-based access control (ABAC) supports both coarse-grained and fine-grained authorization by leveraging attributes to define dynamic and context-aware policies.

Option D: Incorrect. Policy-based access control is a broader term and may include ABAC, but it is not inherently designed for both coarse- and fine-grained authorization.
