Abstract: A method for communication management includes detecting addresses of peer nodes (34) belonging to a service layer (30) of a distributed application running on a computer network (22). Responsively to the detected addresses, filtering of communication traffic transmitted by client computers (26) is actuated so as to limit access by the client computers to the distributed application.
