The Internet represents an essential communication infrastructure that needs to be protected from malicious attacks. Modern network routers are typically implemented using embedded multi-core network processors that are inherently vulnerable to attack. Hardware monitor subsystems, which can verify the behavior of a router's packet processing system at runtime, can be used to identify and respond to an ever-changing range of attacks. While hardware monitors have primarily been described in the context of general-purpose computing, the authors' focuses on two important aspects that are relevant to the embedded networking domain.
