Abstract: 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.

Abstract: Systems of the present disclosure can detect user activities on endpoint devices based on the interference patterns those actions produce in wireless transmissions between those endpoint devices and another device (e.g., an edge device operating as a web security gateway). A web security gateway sends time-series data describing interference on wireless transmissions sent from, or received by, an agentless endpoint device to a network security service. In response, the network security service uses a machine-learning model to infer a type of an action that occurred on the agentless endpoint device concurrently with the wireless transmissions. The network security service sends an indication of the action type to the web security gateway. The web security gateway applies a network security policy to the action or a network communication associated therewith.

Abstract: The present disclosure includes a method for maintaining a dynamic geofence. The method receives a set of digital IDs and data pairs from a monitored user credential. Each digital ID was received by the monitored user credential as part of a wireless transmission from a node device, and each digital ID includes one or more attributes. The method retrieves a user policy that includes a required attribute and a threshold distance. The method determines whether at least one of the digital IDs includes an attribute matching the required attribute, and verifies any digital id containing the attribute matching the required attribute. The method determines the distance between the monitored user credential and the node device using the data paired with the digital ID, and determines whether the distance between the monitored user credential and the node device is less than the threshold distance.
