Kingdom: Encapsulation
Encapsulation is about drawing strong boundaries. In a web browser that might mean ensuring that your mobile code cannot be abused by other mobile code. On the server it might mean differentiation between validated data and unvalidated data, between one user's data and another's, or between data users are allowed to see and data that they are not.
System Information Leak: SignalR Exposed JavaScript Proxy
Abstract
Automatically generated JavaScript proxy files can leak system information as they list all the exposed methods in the Hubs.
Explanation
If you do not want to include all of the hubs and methods in the JavaScript proxy file for each user, you can disable the automatic generation of the file. You might choose this option if you have multiple hubs and methods, but do not want every user to be aware of all of the methods.
