Reino: Encapsulation

La encapsulación consiste en crear límites fuertes. En un explorador web esto puede suponer la seguridad de que tu codificación móvil no se vea comprometido por otro código móvil. En el servidor puede significar la diferenciación entre los datos validados y los que no lo están, entre los datos de un usuario y los de otro, o entre los diferentes usuarios, los datos que pueden ver y los que no.

AWS CloudFormation Misconfiguration: Insecure ElastiCache Storage

JSON
YAML

Abstract

La plantilla define un grupo de replicación de Amazon ElastiCache sin cifrado.

Explanation

De forma predeterminada, los grupos de replicación de Amazon ElastiCache no están cifrados. Esto expone los datos al acceso no autorizado y posible robo.

Ejemplo 1: La siguiente plantilla de ejemplo define un grupo de replicación de Amazon ElastiCache con el cifrado deshabilitado.
