AWS CloudFormation Misconfiguration: FSx Missing Customer-Managed Encryption Key

YAML

Abstract

Una configuración no especifica una clave de cifrado administrada por el cliente para los datos en reposo.

Explanation

Las claves administradas por el cliente no se utilizan para cifrar datos en reposo.

De forma predeterminada, AWS utiliza claves administradas por AWS para cifrar datos en reposo si el cifrado está habilitado. Las claves administradas por el cliente permiten a las organizaciones usar claves criptográficas de su elección para cifrar datos. Esto brinda a las organizaciones un mejor control y registro de los procesos de cifrado.

De este modo, las claves administradas por el cliente suelen ser parte de la solución para satisfacer requisitos que incluyen, entre otros:
- Registros de auditoría para el acceso a datos confidenciales
- Residencia de datos
- Reemplazo, deshabilitación o destrucción de claves

Tenga en cuenta que las claves con el formato aws/service-name están reservadas para las claves administradas por AWS.
