1. A method for the secure use of a network service using a blackboard on which all usable services are entered, the method comprising the steps of:
detecting a service which has not yet been entered on the blackboard;
executing a first check to determine whether use of the service is allowed;
entering the service in the blackboard only if it is determined that use of the service is allowed;
loading an interface driver related to the service on the blackboard;
extending the loaded interface driver on the blackboard with at least one security function to form a secured interface driver;
loading the secured interface driver related to the service prior to the first use of the service; and
executing a second check by a second security function prior to the use of the service to determine if use of the service is allowed by a user.
