An information processing apparatus for connection to a first network and to a second network is disclosed. The information processing apparatus includes a storage unit storing device information in which a device connected to the first network is registered; an authentication unit authenticating an information terminal connected to the second network and registering identification information about the information terminal in registration information responsive to successful authentication of the information terminal; a transition request receiving unit receiving, from the second network, a request for transition to a communication controlled state; and a communication controller restricting information transmission from the second network to the first network in an event of the transition to the communication controlled state made upon receipt of the request, while the communication controller allows, in that event, the information terminal registered in the registration information to transmit information to the device registered in the device information.
