Step-by-Step Creation Process

1. Prerequisites

• Verify check doesn't exist: Search prowler/providers/{provider}/services/{service}/
• Ensure provider and service exist - create them first if not
• Confirm service has required methods - may need to add/modify service methods to get data

2. Create Check Files

mkdir -p prowler/providers/{provider}/services/{service}/{check_name}
touch prowler/providers/{provider}/services/{service}/{check_name}/__init__.py
touch prowler/providers/{provider}/services/{service}/{check_name}/{check_name}.py
touch prowler/providers/{provider}/services/{service}/{check_name}/{check_name}.metadata.json

3. Implement Check Logic

from prowler.lib.check.models import Check, Check_Report_{Provider}
from prowler.providers.{provider}.services.{service}.{service}_client import {service}_client

class {check_name}(Check):
    """Ensure that {resource} meets {security_requirement}."""
    def execute(self) -> list[Check_Report_{Provider}]:
        """Execute the check logic.

        Returns:
            A list of reports containing the result of the check.
        """
        findings = []
        for resource in {service}_client.{resources}:
            report = Check_Report_{Provider}(metadata=self.metadata(), resource=resource)
            report.status = "PASS" if resource.is_compliant else "FAIL"
            report.status_extended = f"Resource {resource.name} compliance status."
            findings.append(report)
        return findings

4. Create Metadata File

See complete schema below and assets/ folder for complete templates. For detailed field documentation, see references/metadata-docs.md.

5. Verify Check Detection

uv run python prowler-cli.py {provider} --list-checks | grep {check_name}
