Abstract
A collection unit (22) collects traffic information generated when data is transmitted from an IoT device connected to the network. When the traffic information collected by the collection unit (22) satisfies the determination condition preset based on a traffic pattern of each IoT device, a determination unit (23) determines that an abnormality occurs in the IoT device that generates the traffic.
Claims6
A determination apparatus comprising:
- a collection unit configured to collect information of traffic generated when based on data being transmitted from a device connected to a network;
- and
- a determination unit configured to determine that an abnormality occurs in the device that generated the traffic based on the information of the traffic collected by the collection unit satisfying a determination condition preset based on a traffic pattern of each of a plurality of the devices.
A gateway that accommodates a device, the gateway comprising:
- an accumulation unit configured to, in response to an instruction from a determination apparatus determining that an abnormality occurs in the device based on information of traffic generated when data is transmitted from the device, stop transferring the data transmitted from the device to the determination apparatus, and to accumulate the data.
A determination method comprising:
- collecting information of traffic generated when data is transmitted from a device connected to a network;
- and
- determining that an abnormality occurs in the device that generated the traffic based on the information of the traffic collected satisfying a determination condition preset based on a traffic pattern of each of a plurality of the devices.
