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.

Insecure Storage: Insufficient Cache Leak Protection

Abstract
O aplicativo tenta desabilitar o cache HTTP(S) definindo a capacidade do cache do disco ou da memória como 0. No entanto, não há garantia de que essa configuração será aplicada.
Explanation
As respostas HTTP(S) podem conter dados confidenciais, como cookies da sessão e tokens de API. O sistema de carregamento de URL armazenará em cache todas as respostas HTTP(S) para fins de desempenho, armazenando-as de forma descriptografada nos arquivos {app ID}/Library/Caches/com.mycompany.myapp/Cache.db*.
Os desenvolvedores podem pensar que ao definir as propriedades diskCapacity ou memoryCapacity da classe URLCache como 0, eles podem estar desabilitando efetivamente o sistema de cache de respostas HTTP(S). No entanto, a documentação de NSURLCache indica que os caches no disco e na memória serão truncados para os tamanhos configurados somente se o dispositivo estiver sendo executado com pouca memória ou pouco espaço em disco. Ambas as configurações são usadas pelo sistema para liberar recursos do sistema e melhorar o desempenho, não como um controle de segurança.
