A method, system and apparatus are described for avoiding the use of a web-server or generic security when providing network administration services remotely to managed entities using wireless technology. Instead a true Proxy device, not operating as a web-server, is used to pre-process all command traffic from wireless input devices (WID). The intervention between the WID and the managed entities of the Proxy isolating the managed entities from the WID, enhanced by encoding using a novel messaging protocol, further enhanced by a novel security model based on multiple pre-shared keys and algorithms together with identifiers and passwords that are not transmitted, achieves several bandwidth and security advantages including the ability to deliver TELNET services across the Internet and behind a firewall.
