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.

Flash Misconfiguration: Unauthorized Data Access

Abstract
O programa permite que aplicativos SWF HTTP e HTTPS se comuniquem.
Explanation
A partir do Flash Player 7, aplicativos SWF carregados via HTTP não podem acessar dados de aplicativos SWF carregados via HTTPS por padrão. O Adobe Flash permite que os desenvolvedores alterem essa restrição programaticamente ou por meio das configurações apropriadas no arquivo de configuração crossdomain.xml. No entanto, é necessário tomar precauções ao definir essas configurações, pois aplicativos SWF carregados via HTTP estão sujeitos a ataques do tipo MITM (man-in-the-middle) e, portanto, não devem ser confiáveis.

Exemplo: O código a seguir chama allowInsecureDomain(), que desativa a restrição que impede aplicativos SWF carregados via HTTP de acessar os dados de aplicativos SWF carregados via HTTPS.
