# Security

<span id="atoti.security.Security" />

Manage the parts of the security config that can be changed without restarting the [`Session`](./atoti.Session#atoti.Session).

<Note>
  This feature is not part of the community edition: it needs to be [unlocked](../guides/unlocking_all_features).
</Note>

* Users with the **ROLE\_ADMIN** are administrators: they have full access to the application.
* Non-administrator users without the **ROLE\_USER** will not be able to access the application.
  See [`individual_roles`](./atoti.security.Security.individual_roles#atoti.security.Security.individual_roles) for an example.
* Users with the **ROLE\_MEASURE\_LINEAGE** can access the [measure lineage](https://docs.activeviam.com/products/atoti/server/6.2/docs/rest-api/diagnostics_rest_api/) REST API, which provides dependency graphs showing parent/child relationships between measures.
