Prowler ThreatScore

Framework ID format: prowler_threatscore_{provider} (e.g., prowler_threatscore_aws)

Prowler ThreatScore is a custom security scoring framework developed by Prowler that evaluates AWS account security based on four main pillars:

Scoring System:

• LevelOfRisk (1-5): Severity of the security issue
  • 5 = Critical (e.g., root MFA, public S3 buckets)
  • 4 = High (e.g., user MFA, public EC2)
  • 3 = Medium (e.g., password policies, encryption)
  • 2 = Low
  • 1 = Informational
• Weight: Impact multiplier for score calculation
  • 1000 = Critical controls (root security, public exposure)
  • 100 = High-impact controls (user authentication, monitoring)
  • 10 = Standard controls (password policies, encryption)
  • 1 = Low-impact controls (best practices)

{
  "Id": "1.1.1",
  "Description": "Ensure MFA is enabled for the 'root' user account",
  "Checks": ["iam_root_mfa_enabled"],
  "Attributes": [
    {
      "Title": "MFA enabled for 'root'",
      "Section": "1. IAM",
      "SubSection": "1.1 Authentication",
      "AttributeDescription": "The root user account holds the highest level of privileges within an AWS account. Enabling MFA enhances security by adding an additional layer of protection.",
      "AdditionalInformation": "Enabling MFA enhances console security by requiring the authenticating user to both possess a time-sensitive key-generating device and have knowledge of their credentials.",
      "LevelOfRisk": 5,
      "Weight": 1000
    }
  ]
}

Available for providers: AWS, Kubernetes, M365

Available Compliance Frameworks

AWS (41 frameworks)

Azure (15+ frameworks)

GCP (15+ frameworks)

Kubernetes (6 frameworks)

Other Providers

• GitHub: cis_1.0_github.json
• M365: cis_4.0_m365.json, iso27001_2022_m365.json
• NHN: iso27001_2022_nhn.json

Best Practices

1. Requirement IDs: Follow the original framework numbering exactly (e.g., "1.1", "A.5.1", "T1190", "ac_2_1")
2. Check Mapping: Map to existing checks when possible. Use Checks: [] for manual-only requirements
3. Completeness: Include all framework requirements, even those without automated checks
4. Version Control: Include framework version in Name and Version fields
5. File Naming: Use format {framework}_{version}_{provider}.json
6. Validation: Prowler validates JSON against Pydantic models at startup - invalid JSON will cause errors

Commands

# List available frameworks for a provider
