To provide the approval device of a command operation for reducing risk of unauthorized operation of an information communication device.

When receiving a command to operate the information communication device 110A from an operator input/output terminal 1101 after user authentication, the approval device of a command operation collates the command with command information stored in a command storage part 1006 to decide whether or not the approval of the command is necessary, and when deciding that approval is necessary by a command approval control part 1010, transmits a signal to inquire for whether or not the approval of the command is necessary to approval terminal equipment 1102 and 1103, and only when receiving an approval response signal from all the approval terminal equipment 1102 and 1103, transmits the command to the information communication device 110A.
