Abstract

System and method generally relate to protection of a bussed network. In such a system, an access controller is configured for bussed communication via a communication bus to obtain a current transaction. An interface firewall is coupled for bussed communication with the access controller and configured to check for a fault associated with a transfer. A data processing device is coupled for communication with the interface firewall and configured to execute the current transaction to provide the transfer for the interface firewall. The interface firewall is configured to detect the fault associated with the transfer, to block access to the data processing device associated with the fault, and to communicate a blocked status for the data processing device.
