  description: |
    Ensure Amazon RDS database snapshots are encrypted for data-at-rest compliance within AWS environments.
  impact: |
    Unencrypted RDS snapshots can expose sensitive data to unauthorized access, risking data breach and non-compliance penalties.
  remediation: |
    Enable encryption for RDS snapshots by using AWS KMS Customer Master Keys (CMKs) for enhanced data security and compliance.
