The present disclosure relates to systems, methods, and computer-readable media for establishing and managing a trusted connection between a peripheral device and a client device. For example, systems discussed herein include determining whether a peripheral device poses a security risk based on a combination of peripheral device data and a client profile including environmental data and historical usage data for the client device. Systems described herein may further grant a level of trust based on the determine security risk. The systems disclosed herein facilitate implementation of intelligent policies that are user friendly without exposing the client device to a variety of security threats.

Establishing a trusted connection with a peripheral device

The present disclosure relates to devices and methods for creating one or more proxy devices in a guest device mirroring the devices hosted by a host device. The proxy devices may provide full device access functionality to applications running in the guest device. The devices and methods may load a proxy driver inside the guest device, which communicates with the host device. When applications running on the guest device interact with the proxy devices, the proxy driver communicates the interaction to the host device, which communicates with the device driver managing the device. The devices and methods allow applications running on the host and applications running on the guest to shares access to the same device.

Providing device abstractions to applications inside a virtual machine

In one aspect, a request is sent to a device for a device descriptor that describes custom interfaces. The custom interfaces may be expressed according to a defined data structure. The device descriptor that describes the custom interfaces is received at a gateway. An interface agnostic application is executed to translate the device descriptor to the custom interfaces for consumption of the data described by the custom interfaces.

Self-describing interfaces for communication with gateways

The disclosed techniques enable a software program to communicate with a peripheral device (e.g., a sensor), via a low-level communication protocol such as the IC protocol, even though the software program does not include lower-level code configured to implement a sequence of operations defined for the low-level communication protocol. The techniques determine that the software program includes a high-level operation that instructs for communications to be conducted with the peripheral device. The high-level operation is associated with a separately stored configuration file that includes the lower-level code configured to implement the sequence of operations enabling the communications to be conducted with the peripheral device via the low-level communication protocol. The techniques then execute the lower-level code included in the configuration file and return information, to the software program, indicating that the communications with the peripheral device have been conducted via the low-level communication protocol.
