The following server permissions were added in SQL Server 2014:
CONNECT ANY DATABASE Permission
Grant CONNECT ANY DATABASE to a login that must connect to all databases that currently exist and to any new databases that might be created in future. Does not grant any permission in any database beyond connect. Combine with SELECT ALL USER SECURABLES or VIEW SERVER STATE to allow an auditing process to view all data or all database states on the instance of SQL Server.
SELECT ALL USER SECURABLES Permission
When granted, a login such as an auditor can view data in all databases that the user can connect to. When denied, prevents access to objects unless they are in the sys schema.
