摘要： A server receives a certificate signing request and onboarding information for an applicant device, and identifies a customer associated with the applicant device based on an applicant device identifier and a database identifiers associated with customers. The device determines a registered device associated with the customer is a trusted device, a location trust value for the applicant device based on a geolocation proximity between the applicant device and the trusted device, and an environment trust value for the applicant device based on a proximity in a network topology between the applicant device and the trusted device. The device further determines a trust score for the applicant device based on the location trust value and the environment trust value, and sends a signed certificate to the applicant device over the network when the trust score for the applicant device exceeds a threshold.

摘要： The disclosed technology relates to systems and methods for automatically scaling down network resources, such as servers or gateway instances, based on predetermined thresholds. A system is configured to detect a reduction in one or more network metrics related to a first server, and instruct the first server to issue a rekey request to a plurality of devices connected to the first server. The system is further configured to instruct a load balancer to route to at least one other server responses from the plurality of devices to the rekey request, and determine a number of connections remaining between the first server and the plurality of devices. The system may be further configured to instruct the load balancer to terminate the first server based on the detected number of connections remaining between the first server and the plurality of devices.
