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 SNS Topic Storage

JSON
YAML

Abstract

La plantilla define un tema de SNS sin cifrar.

Explanation

De forma predeterminada, los temas de SNS no están cifrados en reposo. Esto potencialmente expone los datos a espectadores no autorizados.

Ejemplo 1: La siguiente plantilla de ejemplo no puede cifrar el tema de SNS al no definir un identificador de clave de AWS KMS.


{
    "AWSTemplateFormatVersion": "2010-09-09",

                        "Protocol": "sqs"
                    }
