The protection of critical infrastructure systems is a hotly debated topic. The very label "critical infrastructure" implies that these systems are important, and they are: they support our everyday lives, from the water and food in our homes to our physical and financial welfare. They also support industry and government operation. In an effort to scope the issue, the US National Strategy for Homeland Security has identified 14 areas for critical infrastructure protection, most of which are privately owned. At the heart and soul of nearly every one of these critical infrastructures is a process control system. This article will explore the recent evolution of PCSs and their environments, explain the need for improved security in these systems, and describe some of the emerging research areas that offer promise in PCS security.
