Reino: Encapsulation

Encapsulamento consiste em traçar limites fortes. Em um navegador web, isso pode significar que seu código para dispositivos móveis não pode ser abusado por outros códigos para dispositivos móveis. No servidor, pode significar a diferenciação entre dados validados e não validados, entre os dados de dois usuários ou entre os dados que os usuários podem ou não acessar.

AWS CloudFormation Misconfiguration: Improper API Gateway Access Control

JSON
YAML

Abstract

O modelo define métodos de Gateway da API AWS acessíveis publicamente.

Explanation

Os métodos de Gateway da API AWS que são publicamente acessíveis podem expor a organização a ataques.

Exemplo 1: O modelo de exemplo a seguir define os métodos de Gateway da API AWS acessíveis publicamente.
