Abstract: A method, apparatus and computer-readable medium for testing a target device. A fuzzer and a monitor are connected to the target device via a tactical bus. The fuzzer records messages sent from a source device to the target device over the tactical bus, creates a first fuzzed message having a data structure of the recorded message, and sends the first fuzzed message to the target device over the tactical bus. A fuzzer monitor monitors the target device for an anomalous response to the first fuzzed message, and determines a vulnerability of the target device from the response to the first fuzzed message.

Abstract: A separation kernel isolating memory domains within a shared system memory is executed on the cores of a multicore processor having hardware security enforcement for static virtual address mappings, to implement an efficient embedded multi-level security system. Shared caches are either disabled or constrained by the same static virtual address mappings using the hardware security enforcement available, to isolate domains accessible to select cores and reduce security risks from data co-mingling.
