AWS Image Builder Distribution Configuration is not encrypting AMI by Key Management Service (KMS) u

Rule Details

Cortex AppSec Rule ID	APPSEC_AWS_199
Category - Subcategory	Storage - Encryption
Provider	AWS
Severity	LOW
Framework	Terraform

Impact

This rule identifies Elastic File Systems (EFSs) which are encrypted with default KMS keys and not with Keys managed by Customer. It is a best practice to use customer managed KMS Keys to encrypt your EFS data. It gives you full control over the encrypted data.
