Actor definition for access control design identifies human users and external systems to establish clear permission boundaries, role hierarchies, and authentication methods. It creates a foundational document ensuring no actor's permissions are overlooked in subsequent authorization design.

To define system actors for authorization requirements, you create an actor definition document using a template. You list all human and external system actors, then specify their roles, permitted actions, prohibited actions, authentication methods, and usage environments.

Yes, actor modeling handles multi-tenant role hierarchy structures. The actor definition process requires you to identify and document hierarchical relationships and multi-tenant presence upfront, ensuring the access control design accommodates complex organizational structures.

The best way to document actor permissions and authentication methods is template-driven documentation. A structured template ensures you consistently capture permitted actions, prohibited actions, authentication details, and usage environments for every human and external system actor.

You need to create an actor definition document before designing business flows or feature lists. It serves as a prerequisite to organize user types, roles, and permissions, ensuring the subsequent access control design is built on a validated foundation.

Your authorization design misses external system access boundaries when actor discovery is incomplete. Creating a comprehensive actor definition document ensures both human users and external system integrations are explicitly modeled with their specific permission boundaries and authentication requirements.
