3.1.2 Security Model

For methods that accept a context handle, the security model is a handle-based security model. A client obtains a handle with a client-specified access for that handle. The handle can then be used for operations that require the granted access. The access is encoded in a 32-bit value (an access mask). Note that some methods MUST enforce additional security requirements based on the input.

The security model assumes that whenever a context handle is presented to a method, the identity of the client is the same as the identity of the client that originally opened the handle.<35>
