ABSTRACT:
An information processing apparatus comprises: a protocol pass-preventing device provided between a data transmission side and a data reception side, for causing only a predetermined protocol to pass through the protocol pass-preventing device; description means provided on the data transmission side, for describing a protocol which cannot pass through the protocol pass-preventing device in a data area of a protocol which can pass through the protocol pass-preventing device; and extraction means provided on the data reception side, for extracting the protocol which cannot pass through the protocol pass-preventing device from the data area of the protocol data which can pass through the protocol pass-preventing device. As a consequence, such an information processing apparatus capable of performing communication by using the impermissible protocol can be provided even in such a case that the information processing apparatus are isolated from each other by the protocol pass-preventing device such as the firewall.
