Abstract: A relay apparatus log analysis apparatus 132 periodically receives log data from a relay apparatus 112, when detecting a traffic abnormality, an abnormality detection apparatus 131 notifies the IP address of a terminal device that has caused the abnormality to the relay apparatus log analysis apparatus 132, the relay apparatus log analysis apparatus 132 analyzes traffic information generated by a router apparatus 121 to identify a time when the traffic abnormality has occurred, the relay apparatus log analysis apparatus 132 analyzes the log data, based on the occurrence time of the traffic abnormality and the IP address of the terminal device that has caused the abnormality, identifies an address accessed by the terminal device, regards the identified address as the destination from the malware, and sets the relay apparatus 112 so as to block a packet to the address.

Abstract: When detecting a traffic abnormality, an abnormality detection apparatus 131 notifies a malware infected terminal that has caused the traffic abnormality to a terminal whitelist generation apparatus 133, the terminal whitelist generation unit 133 generates a whitelist indicating software allowed to be installed to the malware infected terminal and setting of a reference terminal device 134 managed not to be infected with the malware, and loads a inspection object extraction program into the malware infected terminal, the inspection object extraction program detects software and setting in the malware infected terminal, and inspects whether or not the detected software and setting coincide with the software and the setting in the whitelist, it is highly likely that software or a setting not coinciding with the whitelist is associated with the malware, by analyzing the software or the setting, the malware may be promptly identified.

Abstract: A magnetic recording medium wind-up method for winding up a long strip-like magnetic recording medium into a coil around a core comprises the steps of pressing the wound-up portion of the magnetic recording medium toward the core with a predetermined pressure while the magnetic recording medium is being wound up around the core. A predetermined length of the magnetic recording medium is wetted, which length will be wound up around the core immediately before the core is fully loaded with the magnetic recording medium, immediately before the predetermined length of the magnetic recording medium is wound up.
