Abstract
A network quarantine management system eliminates registration or updating work of a quarantine-exempted device and prevents a fraudulent device from abusing authorized network information registered as a quarantine-exempted device and from impersonation. When a quarantine management system detects network connection of a new device, the system judges the type (printer, NAS, etc.) of the device by port scanning. The system enables the device to communicate with another device coupled to a business network without an inspection for connecting the device to the business network, if the newly coupled device is judged to be of an authorized type. The device type judgment is conducted whenever a connection is made and is repeatedly conducted after establishment of the connection to check that the type is of an authorized type and, if the type is found to be an unauthorized type, the device is isolated for inspection.
