Abstract: Various embodiments of the present disclosure include a scalable distributed computing and network system that is configured to update multitude of passive devices in many isolated networks. The system may include a centralized update service (CUS) computing device that receives a firmware file, generates a firmware profile, identifies passive devices that include outdated firmware, select one of the identified passive devices as a test device, and send the firmware file to the test device through intermediates and proxy agents. The CUS computing device receives feedback from the test device, generates a trust score for the firmware file based on the received feedback, and determine whether to send the firmware file to the other identified passive devices based on the generated trust score.

Abstract: Various embodiments of the present disclosure include a scalable distributed computing and network system that is configured to install, update or revoke certificates in a multitude of passive devices in many isolated networks. Various embodiments may include a processor in a computing device associating a certificate profile with one or more passive devices in a plurality of passive devices in one or more isolated networks, generating a certificate signing request (CSR) message for each of the associated passive devices, sending the generated CSR messages to a certificate authority, receiving digital certificates from the certificate authority, and sending the received digital certificates to their respective associated passive devices.

Abstract: A system and method for managing multiple instances of a software application running on a single operating system is described. The system may be a server which hosts multiple copies of the same software application running in real time within a framework. The framework prevents the multiple copies of the application from interfering with one another.
