From Prey to Hunter

The authors' global communication infrastructures are powered by large numbers of legacy embedded devices. Recent advances in offensive technologies targeting embedded systems have shown that the stealthy exploitation of high-value embedded devices such as router and firewalls is indeed feasible. However, little to no host-based defensive technology is available to monitor and protect these devices, leaving large numbers of critical devices defenseless against exploitation. They devised a method of augmenting legacy embedded devices, like Cisco routers, with host-based defenses in order to create a stealthy, embedded sensor-grid capable of monitoring and capturing real-world attacks against the devices which constitute the bulk of the Internet substrate.
