AWS Key Management Service
Checks whether the default version of IAM customer managed policies allow principals to use the AWS Key Management Service (KMS) decryption actions on all resources. This control fails if kms:Decrypt or kms:ReEncryptFrom actions are allowed on all KMS keys. The control evaluates both attached and unattached customer managed policies. It does not check inline policies or AWS managed policies.
