# Configuration File
Several Prowler's checks have user configurable variables that can be modified in a common **configuration file**. This file can be found in the following [path](https://github.com/prowler-cloud/prowler/blob/master/prowler/config/config.yaml):
```
prowler/config/config.yaml
```

Also you can input a custom configuration file using the `--config-file` argument.

### Configurable Checks
The following list includes all the AWS checks with configurable variables that can be changed in the configuration yaml file:
