Abstract: When an attack is detected, a controller samples an attack-target addressed DNS reply, received by a border router, from each of the border routers. Then, the controller adds the transmission-source IP address of the sampled DNS reply to the black list of the border router. Furthermore, upon reception of any of a target-addressed DNS reply and a target-addressed UDP subsequent fragment from the IP address that is described in the black list, the controller gives a command to the border router to discard the packet. Furthermore, the controller specifies the setting, for each of the border routers, that DNS replies to a DNS request from the target are excluded from discarding.

Abstract: A control apparatus performs analysis by using partial information and determines whether or not communication is abnormal. If the communication is determined to be abnormal, the control apparatus controls a communication route for a communication control device such that the communication is transmitted from a communication apparatus to the control apparatus. Further, the control apparatus determines whether or not the communication transmitted by the control of the communication route is malicious communication. As a result, if the communication is determined to be malicious communication, the control apparatus controls the communication control device to restrict the malicious communication.

Abstract: The stream data processing system has an input server which accumulates input stream data to be migrated, instructs a migration source and a migration destination to perform data migration, transfers accumulated data to the migration destination in response to an accumulated data transfer instruction, then stops transferring data to the migration source, and transfers subsequent data to the migration destination subsequently to the transfer of the accumulated data. The migration source migrates both a query and an intermediate value that has been produced as a result of completion of execution of the query on input data. A migration destination server reads the accumulated data and the subsequent data that are transferred from the input server, skips reading the portions of these transferred data corresponding to and preceding the migrated intermediate value, and discards the output that is transferred from the migration source and precedes the query execution results.
