In order to provide for efficient security of a remote presentation (such as a remote display) on a client which presents user interface data from a remote server, all requests for action to be performed on the client are examined to determine if they are requests for user interface (UI) presentation. If the request is for UI presentation, it is verified to ensure that the request is valid-e.g., that it comes from an approved source. If the request is a valid UI request, then the request is served. If a UI request cannot be verified, the request is served, if possible, without presenting the user interface data from the request-e.g., by hiding visual data, or playing audio data at zero or minimal volume. Otherwise, the request is not serviced and the connection from the client to the server may be terminated.
