Lightweight Intrusion Detection for Resource-Constrained Embedded Control Systems

Securing embedded control systems presents a unique challenge. In addition to the resource restrictions inherent to embedded devices, embedded control systems must accommodate strict, non-negotiable timing requirements, and their massive scale greatly increases other costs such as power consumption. These constraints render conventional host-based intrusion detection – using a hypervisor to create a safe environment under which a monitoring entity can operate – costly and impractical.
