A communication device has memory for storing a client application module, a server application module, and an operating system module which are executable by one or more processors. The client application module submits a request and, in response, the server application module causes the request to be processed with use of the operating system module. One or more client process handles of a client stack of the client application module are provided in a current process base of the operating system module. For the request, one or more permission settings associated with the one or more client process handles as well as one or more permission settings associated with the one or more server process handles are checked.
