Described herein is a technique to update an edge device deployed in a secure computing network. A repository connected to a public network stores build contents configured to update software installed on the edge device; the public network is inaccessible to devices within the secure computing environment. A second device connected to the public network acquires the build contents in a signed lockbox file. An edge device management service generates a lockbox file containing the build contents and a trusted signer outside the secure computing network signs the lockbox file. The second device connects to secure computing network and establishes communications with the edge device. The edge device verifies the signed lockbox file provided by the second device. Upon verification, the edge device extracts the contents of the signed lockbox file and updates the software installed on the edge device. Both offline and online updating approaches are described.

Described herein are techniques for integrating external sensors to an edge device, such as for ingesting data into a data intake and query system. The edge device has an internal message broker for communicating with internal (e.g., preconfigured, recognized) sensors, and an external message broker for communicating with external (e.g., customer-configured, otherwise unrecognized) sensors. The external message broker provides access to customer configuration of external sensors, but is logically quarantined from the internal message broker to prevent unwanted customer access to internal configurations. The internal and external message brokers interface only via a bridging service that transforms external sensor data into data based on customer-configurable transformations. The transformed data can be handled by the edge device and/or downstream components (e.g., a data intake and query system) in the same manner as internal sensor data.

External sensor integration at edge device for delivery of data to intake system

A wrapper layer over a target interface receives requests from client devices over a different interface, converts the requests into a format that is compatible with the target interface, and transmits each converted request over the target interface for processing by a service. The wrapper layer also processes a request by a client device to subscribe to a certain type of update made via the target interface by verifying that the client device is authorized to access a resource associated with that type of update and creating a subscription that identifies the client device and the type of update. When the wrapper layer subsequently receives a request corresponding to that type of update, the wrapper layer matches attributes of the request to the subscription by the client device and transmits a message notifying the client device of the request.
