Abstract: There is disclosed in one example a computing apparatus, including: a hardware platform including at least a processor and a memory; and a security agent including instructions encoded in the memory to instruct the processor to: monitor a user's operation of the computing apparatus over time, including determining whether a selected behavior is a security risk; provide a risk analysis of the user's operation based at least in part on the monitoring; select a scan sensitivity based at least in part on the risk analysis; and scan, with the selected sensitivity, one or more objects on the computing apparatus to determine if the one or more objects are a threat.

Abstract: Managing authentication of a child device includes receiving, by a host device, sensor data from a child device, deriving simplified authentication data from the sensor data based on a capability of the child device, storing the simplified authentication data in an authentication profile for the child device, and transmitting the simplified authentication data to the child device, wherein the simplified authentication data is sufficient to allow the child device to authenticate a user without the host device.

Abstract: Pairing two devices includes detecting, by a first device, a trigger event that indicates that a second device is within a predetermined proximity, obtaining a first time stamp indicating a time of the trigger event as recorded by the first device, determining whether a difference between the first time stamp and a second time stamp satisfy a predetermine threshold, where the second time stamp indicates a time of the trigger event as recorded by the second device, and in response to determining that the difference between the first time stamp and the second time stamp satisfies the predetermined threshold, allowing the first device to pair with the second device.
