A dynamic authorization model makes access decisions from changing policies, identities, resources, relationships, and context—not from fixed permissions alone. It helps organizations handle conditions such as a user’s region, a record’s sensitivity, a document relationship, or the time of day. section 6.0
Dynamic authorization addresses the point where static permissions and accumulating exceptions become difficult to review and keep consistent across systems. Declarative policies provide the layer connecting identity and resource data with business and security conditions. section 6.0 section 5.0
Common dynamic approaches include:
- Relationship-Based Access Control (ReBAC) grants access according to a user’s relationship to a resource, such as viewer, editor, or owner. section 6.0
- Attribute-Based Access Control (ABAC) evaluates attributes such as region, clearance, time of day, and record sensitivity. section 6.0
- Role-Based Access Control (RBAC) remains useful for broad responsibilities, onboarding, and governance, while dynamic models handle finer variations. section 6.0
A mixed authorization strategy
ACME retains RBAC for broad job responsibilities, uses ReBAC so Alice can access documents where she is a viewer, editor, or owner, and applies ABAC so Bob’s customer-data access depends on region and record sensitivity. Carol gains fewer exceptions and better visibility into why access is granted. section 6.0
Dynamic models complement rather than replace static models. Their operational value depends on policies that remain aligned with identity data, resource metadata, business intent, security requirements, and audit needs. section 6.0 section 1.0
