New attacks are emerging that target the Internet infrastructure. Modern routers use programmable network processors that may be exploited by merely sending suitably crafted data packets into a network. Hardware monitors that are co-located with processor cores can detect attacks that change processor behavior with high probability. In this paper, we present a solution to the problem of secure, dynamic installation of hardware monitoring graphs on these devices. We also address the problem of… CONTINUE READING
