A communication system includes a server that matches a packet against a definition pattern, provided for determining whether the packet is an invalid packet, and discards the packet if the packet is an invalid packet and, for other packets, notifies processing content, which is applied to the packets, to a sending source; and a communication device that forwards an unknown packet to the server and, based on processing content notified from the server, processes a received packet. |
