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 a router that establishes a connection between a first network and a second network different from the first network, the first network including an information processing device and an information storage device, the method comprising:

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 second network for a period including a first period of time for which the information processing device accesses a specified folder in the information storage device, on a basis of the access status.

2. The method according to claim 1, wherein

the detecting includes acquiring the access status from the information storage device.

3. The method according to claim 2, wherein

the detecting includes managing a period of time during which transfer of the information from the information processing device to the second network is prohibited in the prohibiting.

4. The method according to claim 3, further comprising:

detecting a connection between the information processing device and the second network.

5. The method according to claim 4, wherein

the detecting includes managing a connection status between the information processing device and the second network.

6. The method according to claim 5, wherein

the detecting includes managing a period of time, during which an access from the information processing device to the information storage device is prohibited, depending on a connection status between the information processing device and the second network.

7. The method according to claim 1, wherein

the period includes a second period of time before or after the first period of time.
