Abstract

A method executed by a router that establishes a connection between a network and an another network that includes an information processing device and an information storage device, the method includes: detecting an access status of the information processing device to the information storage device; and prohibiting transfer of the information from the information processing device to the another network depending on the access status managed in the detecting.

Claims

1. A method executed by an information storage device that is connected to an information processing device via a network, the method comprising:

generating a characteristic pattern corresponding to a file held in the information storage device;

storing the characteristic pattern;

searching for a file corresponding to the characteristic pattern;

detecting a file access from the information processing device to the information storage device; and

when a file corresponding to the characteristic pattern has been newly detected in the searching, adding the detected file as a monitoring target in the detecting.
