aws-cis-controls-assessment 1.0.10

Production-ready AWS CIS Controls compliance assessment framework with 145 comprehensive rules

AWS CIS Controls Compliance Assessment Framework

A production-ready, enterprise-grade framework for evaluating AWS account configurations against CIS Controls Implementation Groups (IG1, IG2, IG3) using AWS Config rule specifications. 100% CIS Controls coverage achieved with 133 implemented rules plus 5 bonus security enhancements.

Production Status: This framework is production-ready and actively deployed in enterprise environments. It provides comprehensive point-in-time compliance assessments while we recommend AWS Config for ongoing continuous compliance monitoring and automated remediation.

🆕 What's New in Version 1.0.10

AWS Backup Service Controls

Six new controls added to assess AWS Backup infrastructure:

IG1 Controls (3):

1. backup-plan-min-frequency-and-min-retention-check - Validates backup plans have appropriate frequency and retention policies

   • Ensures backup plans have at least one rule defined
   • Validates schedule expressions (cron or rate)
   • Checks retention periods meet minimum requirements (default: 7 days)
   • Validates lifecycle policies for cold storage transitions

2. backup-vault-access-policy-check - Ensures backup vaults have secure access policies

   • Detects publicly accessible backup vaults
   • Identifies overly permissive access policies
   • Warns about dangerous permissions (DeleteBackupVault, DeleteRecoveryPoint)
   • Validates principle of least privilege

3. backup-selection-resource-coverage-check - Validates backup plans cover critical resources

   • Ensures backup plans have at least one selection
   • Validates selections target specific resources or use tags
   • Checks that selections are not empty

IG2 Controls (3): 4. backup-vault-lock-check - Verifies vault lock for ransomware protection

• Ensures critical vaults have Vault Lock enabled
• Validates immutable backup configuration (WORM)
• Checks minimum and maximum retention periods

5. backup-report-plan-exists-check - Validates backup compliance reporting

   • Ensures at least one report plan exists
   • Validates report delivery configuration
   • Checks for active report generation

6. backup-restore-testing-plan-exists-check - Ensures backups are recoverable

   • Validates restore testing plans exist
   • Checks testing schedules are configured
   • Ensures backups are actually tested for recoverability

These controls complement the existing 12 resource-specific backup controls by assessing the centralized AWS Backup service infrastructure itself. Total backup controls: 17 (12 resource-specific + 5 service-level). See AWS Backup Controls Guide for detailed documentation.
