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.
