Access Management Has Layers: Where RBAC, ABAC, and Attestation Fit
RBAC and ABAC help determine what access should be allowed. Attestation answers a different question: whether an approved change was actually completed.
These tools do not compete for the same job
Access management is often discussed as if an organization must choose one model. In practice, a mature process has several layers. One layer decides what access should be allowed. Another applies the change in the real system. A third keeps track of whether the approved work was completed and what evidence remains afterward.
Role-based access control (RBAC) and attribute-based access control (ABAC) belong primarily to the authorization layer. Permission Report belongs to the accountability layer. An organization can use either authorization model—or a mixture of both—and still use attestation to close the gap between an approved change and recorded completion.
Two common authorization models
Role-Based Access Control (RBAC)
Common foundationPermissions are associated with roles such as “Sales Representative” or “Finance Manager.” People receive the access connected to the roles they hold.
Best Used When
- Jobs have repeatable access needs
- Role ownership and membership stay understandable
- Consistent onboarding matters more than one-off exceptions
Limitations
- Edge cases can create too many narrowly defined roles
- Role membership can drift as people change responsibilities
- A role assignment does not prove downstream provisioning occurred
Attribute-Based Access Control (ABAC)
Policy-drivenAccess decisions evaluate attributes of the requester, resource, requested action, and sometimes the environment against defined policies.
Best Used When
- Access depends on context such as department, location, data class, or time
- Policies must work across many users and resources
- Fine-grained decisions justify the added complexity
Limitations
- Attribute quality and policy design require ongoing governance
- Decisions can be harder for non-specialists to explain
- A policy decision still does not prove a separate manual task was completed
The execution layer is where the real change happens
After authorization, something must apply the change. A connected identity platform may provision the account automatically. An application owner may update a local admin console. A facilities manager may issue a badge. A department lead may rotate a shared credential. An equipment manager may hand over or recover a laptop.
That mix is normal, especially in growing organizations. The risk appears when the organization treats the approved request as proof that every downstream action happened.
Attestation closes the accountability gap
Permission Report starts after the authorization decision. When an authorized originator adds a permission change, the product treats it as approved work. It routes that work to the designated manager, tracks the effective date and status, and requires a written sign-off to complete it.
The resulting record connects organizational intent to a named person’s report of fulfillment. It does not enforce access inside the external system, and it does not independently verify the responder’s statement. Its value is visibility and accountability: pending work stays visible, overdue work is identifiable, and completed or cancelled work remains reviewable.
What a practical stack can look like
The right stack is not determined by company size alone. It depends on the number of systems, how access is administered, the sensitivity of the resources, and how much reviewable evidence the organization needs. The important point is to avoid asking one layer to perform a job it was not designed to do.
- Use role templates to express repeatable access needs for common jobs
- Use application or identity-provider controls to enforce access where integrations exist
- Track local accounts, shared access, physical credentials, and equipment that sit outside those integrations
- Route approved additions and removals to the people who actually administer each resource
- Require a specific sign-off when the real-world work is complete
- Review current holdings and change history periodically for drift or missing work
Where Permission Report fits
Permission Report is not an identity provider and does not replace RBAC, ABAC, SSO, or application-level authorization. It provides a system of record for permissions and equipment, a workflow for approved changes, named responsibility for fulfillment, and retained sign-offs for later review.
That makes it useful precisely where access management crosses organizational boundaries: HR knows someone is leaving, IT controls the central identity, individual managers own specialized systems, and facilities or operations owns physical assets. Permission Report keeps the approved work and its sign-offs in one place.
