Abstract: Methods and systems for updating a virtual terminal associated with a secure network are disclosed. One method includes validating at a service enclave an identity of a user of a virtual terminal. The service enclave includes an authorization server, and the virtual terminal is generated from a trusted set of processing modules executing from a secure boot device at a client computing device. The method further includes authorizing the user of the virtual terminal to access a customer enclave and an update enclave based on security credentials received from the virtual terminal. The method also includes, while the user of the virtual terminal establishes a secure connection between the client computing device and the customer enclave, transmitting updates from the update enclave to the client computing device, thereby updating the trusted set of processing modules.
