Object-Oriented Security is the practice of using common object-oriented design patterns as a mechanism for access control. Examples of object-oriented security practices include everything EXCEPT for:
Preventing an object from accessing another object by never giving the first object a reference to the second
Granting permanent access to an object by wrapping it in a revocable forwarder
Restricting the usage of an object by wrapping it in a narrower interface
Preventing misuse by designing an interface so that it is difficult or impossible to use incorrectly
When wrapping an object in a revocable forwarder, never grant permanent access. One should only grant temporary access.
