ABSTRACT:
A packet filtering apparatus includes a first network interface which receives a first packet from a communication device located in a first network, and a sender information acquiring unit which acquires sender information including at least one of security information about the communication device and authentication information about a user of the communication device. The packet filtering apparatus also includes an evaluation information creator which creates evaluation information indicating security evaluation of the communication device based on an evaluation criterion for the sender information, an evaluation information adder which adds the evaluation information to the first packet to generate a second packet, and a second network interface which transmits the second packet to a second network.
