RBAC is the most widely adopted access control model in enterprise software. Enterprise customers expect fine-grained access controls that let them manage permissions for their team members.
|-------|-------------|----------|
| RBAC | Permissions assigned to roles, roles assigned to users | Most B2B SaaS applications |
|---|---|---|
| ACL | Permissions assigned directly to users per resource | Simple file/resource systems |
Traditional RBAC checks roles at the application level ("is this user an admin?"). Resource-level RBAC extends this to individual resources ("can this user edit document #123?"). This is critical for multi-tenant SaaS where users need different permissions on different resources.
When access is denied, users and administrators need to understand why. An RBAC Explain Graph traces the decision path showing which roles were checked, which permissions were evaluated, and where the denial occurred.
Trailbase provides resource-level RBAC with an Explain Graph for every access decision. Permissions are checked down to individual resource IDs, and every decision is audit-logged. The Explain Graph makes debugging access issues straightforward.
