A method for isolating a computer platform includes receiving a service request from an external requestor via a network at processing circuitry associated with a hardware barrier between the computer platform and the network, causing the service request to be loaded into a first buffer having a dual port connection to a corresponding second buffer of the computer platform, providing an indication to the computer platform to indicate the service request is loaded into the first buffer to be pulled into the second buffer of the computer platform, responsive to processing of the service request by the computer platform, receiving a message indicating a response loaded in the second buffer has been pushed to the first buffer, and communicating the response to the external requestor. The buffers form the only access point to the computer platform. The indication is the only communication initiated from the external requestor that crosses the hardware barrier without control by the computer platform.
