Recording medium recording a network shutdown control program, and network shutdown device

摘要

A recording medium recording a network shutdown control program permitting suitable preventive measures to be taken. A detector monitors each network segment to be managed, and on detecting a communication fulfilling a predetermined condition, the detector generates a detection notification and sends the notification to a quarantine manager. On acquiring the detection notification generated by the detector of the local device or a detection notification generated by a remote network shutdown device, the quarantine manager generates a shutdown operation request in accordance with quarantine policy stored in a quarantine policy storage, and sends the request to a communication shutdown unit. In accordance with the shutdown operation request, the communication shutdown unit sets shutdown data identifying a target of shutdown and controls packets to be input to and output from the network segment so that the packets may be shut off or passed.
