Abstract: A system and method for securely exchanging information between a server and an endpoint. A firewall and switch may administer connections between the endpoint and the server. The network interface of the server may send and receive information through the firewall and switch. A program task in the sever may set the network interface to be in an “on state” for a predetermined amount of time on a specific date thereby creating an active time transfer window that the network interface can receive communications from the endpoint.
