Yesterday the idea that computer security issues could lead to a life or death situation was hyperbole. Today the breadth and depth of devices that are or are becoming computerized ("Internet of Things"), our increasing intimacy with technology (wearables and soon implants), the ubiquity of Internet access, and our increasing dependence on all of the above means that yesterday's fear-mongering is today's reality.

We are not newcomers to this problem. We have experience building and evaluating the security of a wide range of non-commodity IT devices and systems, hardening them against attack, and developing solutions to the seemingly intractable problems associated with keeping high-reliability systems both up and secure.
