Measuring Cyber

How do we quantify safety and security? That fundamental question underlies almost all modern national security questions (and, naturally, most commercial questions about risk as well). The cost-benefit analysis inherent in measuring safety and security drives decisions on, to cite just a few examples, new car safety devices, airplane maintenance schedules and the deployment of border security systems. In a world where resources are not infinite, some assessment of risk and risk mitigation necessarily attends any decision—whether it is implicit in the consideration or explicit.
