Securing of internet of things devices based on monitoring of information concerning device purchases
Purchasing related activity that is executed on computing devices on a LAN is monitored. Information is identified concerning purchases of IoT devices on the LAN, based on the monitoring of the purchasing related activity. For example, a specific purchase of a specific device (or specific device type) can be identified, or identifying information concerning a purchased device can be inferred, based on monitored purchasing related activity. IoT devices are discovered on the LAN and identified. Identifying a discovered device can further comprise interrogating the discovered device, monitoring activities of the discovered device, and/or analyzing information concerning purchases of IoT devices on the LAN. Gleaned identifying information concerning a discovered device can be used to determine or disambiguate the device's identity. Identifying information concerning discovered devices can be transmitted to a backend component, which provides constraint profiles concerning discovered devices, which can be enforced on the LAN.
