Cyber attacks are becoming more common and brazen. You may already have been a victim of one of these attacks and only find out when your credit card company calls to asks about suspicious activity. Many of the attacks that are in the news are focused on obtaining “personal identifiable information” such as credit card numbers, bank accounts, and social security numbers. But there is a whole other target for these cyber criminals, and that is the area of cyber-physical systems including industrial control systems, infrastructure controls such as the electrical grid, and even controls for building systems. While not as well publicized as financial and personal information attacks, both are a very real risk and a clear and present danger.
