Title (EN) UNAUTHORIZED PACKET COUNTERMEASURE DEVICE, SYSTEM, METHOD, AND PROGRAM
(FR) DISPOSITIF, SYSTÈME, PROCÉDÉ ET PROGRAMME DE CONTREMESURE CONTRE DES PAQUETS NON AUTORISÉS
(JA) 不正パケット対策装置、システム、方法及びプログラム
Abstract:
(EN) In order to take countermeasures against unauthorized communications without stopping a communications system, this unauthorized packet countermeasure device has: a transmitter/receiver that receives, as a received packet, a packet sent from a first communications device via a relay device and sends a response packet to the first communications device; a determination unit that determines whether or not the received packet is a packet asking for a MAC address corresponding to the IP address for a second communications device; and a packet generator that, when the received packet is that kind of packet, generates, as a response packet, a packet including a MAC address other than said MAC address, as a MAC address corresponding to the IP address, and outputs the response packet to the transmitter/receiver.
(FR) Afin de prendre des contremesures contre des communications non autorisées sans arrêter un système de communication, le dispositif de contremesure contre des paquets non autorisés a : un émetteur/récepteur qui reçoit, en tant que paquet reçu, un paquet envoyé d’un premier dispositif de communication via un dispositif relais et envoie un paquet de réponse au premier dispositif de communication ; une unité de détermination qui détermine si le paquet reçu est ou non un paquet demandant une adresse MAC correspondant à l’adresse IP pour un second dispositif de communication ; et un générateur de paquet qui, lorsque le paquet reçu est cette sorte de paquet, génère, en tant que paquet de réponse, un paquet incluant une adresse MAC autre que ladite adresse MAC, en tant qu’adresse MAC correspondant à l’adresse IP, et délivre le paquet de réponse à l’émetteur/récepteur.
(JA) 通信システムを停止させずに、不正な通信に対して対策をとる。不正パケット対策装置は、第1通信装置から送信されたパケットを、中継装置を介して受信パケットとして受信し、応答パケットを第1通信装置に送信する送受信機と、受信パケットが、第2通信装置のIPアドレスに対応するMACアドレスを問い合わせるパケットであるか否かを判定する判定器と、受信パケットがそのようなパケットである場合に、前記MACアドレス以外のMACアドレスを前記IPアドレスに対応するMACアドレスとして含むパケットを、応答パケットとして生成し、送受信機に出力するパケット生成器とを有する。
