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.

System Information Leak: SignalR Exposed JavaScript Proxy

C#/VB.NET/ASP.NET

Abstract

Los archivos de proxy en JavaScript generados de forma automática pueden tener pérdidas de información del sistema, ya que enumeran todos los métodos expuestos en los concentradores.

Explanation

Si no desea incluir todos los concentradores y métodos en el archivo de proxy en JavaScript de cada usuario, puede desactivar la generación automática del archivo. Puede decidirse por esta opción si tiene múltiples concentradores y métodos, pero no desea que cada usuario esté al tanto de todos los métodos.
