  • Execute specific check(s): 
    prowler <provider> -c/--checks s3_bucket_public_access
  • Exclude specific check(s): 
    prowler <provider> -e/--excluded-checks ec2 rds
  • Execute checks that appears in a json file: 
    <checks_list>.json

{
    "<provider>": [
        "<check_name_1",
        "<check_name_2",
        "<check_name_3",
        ...
    ],
    ...
}

    prowler <provider> -C/--checks-file <checks_list>.json

Custom Checks

Prowler allows you to include your custom checks with the flag: 

prowler <provider> -x/--checks-folder <custom_checks_folder>

Note

S3 URIs are also supported as folders for custom checks, e.g. s3://bucket/prefix/checks_folder/. Make sure that the used credentials have s3:GetObject permissions in the S3 path where the custom checks are located.

The custom checks folder must contain one subfolder per check, each subfolder must be named as the check and must contain:

  • An empty __init__.py: to make Python treat this check folder as a package.
  • A check_name.py containing the check's logic.
  • A check_name.metadata.json containing the check's metadata.
Note

The check name must start with the service name followed by an underscore (e.g., ec2_instance_public_ip).

To see more information about how to write checks see the Developer Guide.

Note

If you want to run ONLY your custom check(s), import it with -x (--checks-folder) and then run it with -c (--checks), e.g.: 

prowler aws -x s3://bucket/prowler/providers/aws/services/s3/s3_bucket_policy/ -c s3_bucket_policy

Each of Prowler's checks has a severity, which can be: - informational - low - medium - high - critical

To execute specific severity(s): 

prowler <provider> --severity critical high
