Abstract: front page image
(EN)With one embodiment of the present invention, the improper operation of files in a computer that is being monitored is detected in a computer system that includes multiple computers which are connected via a network. The computer being monitored receives a file. The computer receives information about the source of the file, transmitted from another computer. The computer references information about improper operation conditions, and determines whether the transmission of the file satisfies the improper operation conditions on the basis of a combination of the source indicated by the source information for the file and the destination of the file. When these conditions are satisfied, the transmission of the file is determined to be an improper operation.
(FR)Un mode de réalisation de la présente invention permet de détecter, dans un système informatique comprenant de multiples ordinateurs en réseau, l'utilisation incorrecte de fichiers dans un ordinateur contrôlé. L'ordinateur contrôlé reçoit un fichier. L'ordinateur reçoit des informations relatives à la source du fichier, transmises à partir d'un autre ordinateur. L'ordinateur référence les informations relatives aux conditions d'utilisation incorrecte et détermine si la transmission du fichier correspond aux conditions d'utilisation incorrecte sur la base d'une combinaison de la source indiquée par les informations de source relatives au fichier et de la destination du fichier. Lorsque ces conditions correspondent, la transmission du fichier est déterminée comme étant une utilisation incorrecte.
(JA) 本発明の一実施形態は、ネットワークにより接続された複数の計算機を含む計算機システムにおいて、監視対象の計算機におけるファイルの不正操作を検知する。監視対象の計算機はファイルを受信する。前記計算機は、他の計算機から送信された、前記ファイルの入手元情報を受信する。前記計算機は、不正操作条件の情報を参照して、前記ファイルの前記入手元情報が示す入手元と前記ファイルの送信先との組み合わせに基づき、前記ファイルの前記送信が不正操作条件を満たしているか否かを判定し、その条件が満たされている場合に、前記ファイルの前記送信を不正操作と判定する。
