# Process

Valtimo is built on top of Camunda, it uses Camunda to create BPMN processes.

This section contains information on how to configure and use BPMN processes in Valtimo.

* [System processes](https://docs.valtimo.nl/v12/features/process/systemprocesses)
* [Correlating messages](https://docs.valtimo.nl/v12/features/process/correlation-service)
* [Manipulating jobs](https://docs.valtimo.nl/v12/features/process/job-service)

## Access control

Access to the processes can be configured through access control. More information about access control can be found [here](https://docs.valtimo.nl/features/access-control).

### Resources and actions

<table><thead><tr><th width="329">Resource type</th><th width="143">Action</th><th>Effect</th></tr></thead><tbody><tr><td><code>com.ritense.valtimo.camunda.domain.CamundaExecution</code></td><td><code>create</code></td><td>Allows creating an execution for a process definition.</td></tr><tr><td><code>com.ritense.valtimo.camunda.domain.CamundaProcessDefinition</code></td><td>-</td><td>-</td></tr></tbody></table>

Process definitions have no actions currently. As a result, they can only be used as part of container conditions. See the example [here](#permission-to-start-a-process-for-one-specific-process-definition) on how to use this.
